It sounds straightforward, but it is surprisingly difficult to answer. We know the end of the story much better than the beginning. By the central Middle Ages, Orkney and Shetland were overwhelmingly Norse-speaking societies, closely connected politically, culturally and linguistically with Norway and the wider Scandinavian North Atlantic. Their place-names are overwhelmingly Norse. Before the Viking Age, however, the islands belonged to a Pictish and Insular Christian world. Somewhere between those two points something very profound happened.

For a long time, discussions, or perhaps arguments, has tended to swing between two extremes. One sees Scandinavian settlement as violent conquest and demographic replacement: newcomers displaced, overwhelmed or perhaps largely eliminated the indigenous population. I used to be a fairly card-carrying member of this team! The other explanation emphasises continuity, intermarriage and integration, with Scandinavians settling among existing inhabitants and a new society gradually emerging. This has sometimes been described as the Peace School.

I am increasingly wondering whether this is the wrong choice. Violence and integration need not have been opposites. More importantly, both interpretations can quietly share the same assumption: that the people doing the Viking activity were Scandinavians, while the islanders were the people to whom Viking activity happened. Two rather different bodies of scholarship have made me question that assumption. The first is the history of pirate communities, which shows how maritime raiding systems depended upon, recruited from and became entangled with shore populations. The second is Island Studies, which warns us against assuming that small island communities are inherently passive or vulnerable. Add to that the awkward medieval fact that non-Scandinavians such as Wends could themselves be called vikings, and another possibility begins to appear. Perhaps Orcadians and Shetlanders became Vikings before their islands became Norse. Hold that thought!

What pirates can tell us about Vikings

I am not suggesting that ninth-century Vikings were early copies of Jack Sparrow, simply Caribbean pirates with different ships. The worlds of Port Royal, Nassau and the Barbary corsairs belonged to very different political, technological and economic circumstances. But the comparison is useful because pirates are comparatively well documented. Their records help us to see the social world behind maritime raiding in much greater detail than we usually can for the early Viking Age.

What emerges is much messier and more interesting than the popular picture of outlaw crews living independently at sea. Successful pirate communities needed land. They needed harbours, food, markets, ship repair, intelligence, merchants prepared to buy stolen goods, and officials willing to turn a blind eye. Hanna’s study of early-modern ‘pirate nests’ shows how closely piracy could become embedded within ordinary shore-based economies (Hanna, 2015). McDonald similarly demonstrates how pirates, merchants, settlers and enslaved people formed overlapping networks across the Atlantic world (McDonald, 2015).

A pirate, in other words, was not necessarily a member of a separate pirate population. A sailor could be a merchant on one voyage, a privateer on another and a pirate on the next. A pirate settlement might contain respectable traders who profited handsomely from piracy without ever boarding a pirate ship. Ports did not merely suffer piracy; some helped sustain it, profited from it, supplied it and recruited into it.

Presumably, medieval Scandinavian pirates needed the same kinds of things that later pirate communities needed: shelter, food, fresh water, local intelligence, repairs, pilots, markets and people who knew the coast. A maritime predatory system cannot exist offshore from society. It has to touch land repeatedly, and every landing creates possibilities for exchange, coercion, collaboration and recruitment.

Because the Vikings were pirates! Medieval writers themselves sometimes used precisely that language. Frankish annalists called Scandinavian raiders piratae: the Annales Bertiniani could describe attackers as piratae Danorum, ‘Danish pirates’, or piratae Nordmannorum, ‘pirates of the Northmen’. The Annales regni Francorum similarly refers to Scandinavian piraticae naves, ‘pirate ships’. Most strikingly, Adam of Bremen later wrote of pyratae, quos illi Wichingos appellant — ‘pirates, whom they call Vikings’. Modern English has turned Viking into something close to an ethnic label. We speak easily of Viking farmers, Viking women, even Viking children, but the Medieval usage was narrower. Of course, that’s not suprising as most of these pirates were of Scandinavian origin. However, in Old Norse víkingr referred to any person engaged in Viking activity, and that activity was víking ‘piracy’, and John Lind reminds us that Medieval Icelandic writers could apply víkingr to raiders who were not Scandinavian at all.

In Hákonar saga góða, Snorri describes Hákon killing víkingar wherever he found them and identifies them as ‘both Danes and Wends’. The Wends were a Slavic people. Elsewhere Wends, Curonians, Estonians and other eastern raiders could also be described as vikings when engaged in piratical predation (Lind, 2012). Viking described what somebody was doing rather than where their ancestors came from. If a Wend could be a víkingr without becoming Scandinavian, why couldn’t a Pict from Orkney or Shetland also participate in the same kind of behaviour?

This is where I am going to present two ungainly neologisms, Vikingisation and Norseisation. By Vikingisation I mean participation in raiding, trading, slaving and armed voyaging networks. By Norseisation I mean the much deeper adoption of Norse language, names, political structures, law, landholding and cultural identity. The first could begin before the second. I am becoming more and more convinced we see this process in the Northern Isles.

The pirate comparison also helps us to visualise the latter concept. Pirate frontiers are rarely permanent. States attempt to suppress them, co-opt them or regularise them. This is strikingly similar to the process described in the saga tradition about Harald Finehair King of Norway, and the vikings who were based in Shetland and Orkney, who were using the islands as winter refuges, from which to raid Norway in the summer. Of course, this Harald could not thole, so he eventually responded by sailing his fleet west conquering Shetland and Orkney, and placing them under royal control, and granting them to Jarl Rögnvaldr of Møre, ancestor of the Jarls of Orkney (Orkneyinga saga, ch. 4; Pálsson and Edwards, 1978). The saga makes no comment about the ethnicity of the offending vikings. Harald roots them out because their activities threatened his authority in Norway.

We can’t treat the expedition itself as straightforward ninth-century history. Orkneyinga saga was written centuries later, and the Harald narrative has long been suspected of projecting later Norwegian claims to lordship over the islands back into a previous century. However, that is not a problem. What matters is the kind of past the saga writer was imagining. He envisages a stage before stable Norwegian lordship when the Northern Isles functioned as bases for autonomous maritime raiders, a Viking Orkney and Shetland, before the creation of a Norwegian Orkney and Shetland.

Could a Pict become a Viking?

Pirate literature tells us that predatory pirate communities could be porous. People on shore could provision raiders, trade with them, collude with them in their nefarious activities, marry into their networks, serve as brokers, or just join them. If we apply this perspective to the Viking Age, we could ask how did existing island communities respond to an expanding maritime economy of violence, exchange and mobility? Did they collude?

This is an important question, because invasion narratives usually make local people passive recipients of whatever was thrown at them. We tend to ask what did the newcomers do to them? But people living around maritime frontiers could make choices, even when those choices were constrained by violence and unequal power. Some would resist, some negotiate, some trade, some supply ships, and some would collaborate with raiders against their rivals.

The ninth-century Life of St Findan provides us with an interesting example from the Insular world. Unfortunately for the young Findan, his Irish enemies deliberately arranged for Scandinavian raiders to have him seized. The situation wasn’t simply Irish people on one side and Vikings on the other. Viking violence could be used by locals for their own purposes. Findan was sold between various Scandinavian owners before finding himself being carried north by ship. The vessel reached ‘the Orkney Islands, close to the land of the Picts’. When the crew went ashore to rest, explore and wait for a favourable wind, Findan managed to make his escape.

This is exactly the kind of encounter that pirate history makes easier to imagine. There doesn’t need to have been a Viking farm, nor a permanent Scandinavian colony, nor any conquest as such, for Orkney to have become part of the Viking operational world. The islands could have functioned as stopping places, provisioning points and nodes in a wider network before their landscape looked recognisably Norse.

Now imagine the same process from the island side. Two local families compete for influence. One resists Scandinavian crews. Another supplies food and navigational knowledge. That second family gains silver, prestige or military assistance. A son learns Norse and joins a voyage; he returns with wealth. Success! A daughter marries into a Scandinavian-connected household. Another success! Within two or three generations the second family might look thoroughly Norse to an archaeologist. The first family disappears into obscurity.

No one has simply ‘assimilated’ them. They have participated in a changing maritime system. That’s why I think participation might be a better word than assimilation. Why can we not envision some Picts participating in the very Viking world in which their descendants later lived?

Vulnerable islands or resilient islanders?

There is another reason, I think, why the possibility of active indigenous participation has been easy to overlook: the way islands themselves are imagined. From the mainland perspective islands are often described through the language of smallness, isolation, exposure and vulnerability. If that is your starting point, and lets face it most academics are mainlanders, it is easy to picture Viking ships arriving from outside and overwhelming a fragile island society. Islanders become the people to whom history happens.

However, the discipline of Island Studies has spent a good deal of time questioning this stereotype. Islands and islanders can be vulnerable, of course, but they are often very resilient. Smallness, boundedness and isolation don’t automatically produce weakness, they can produce resilience and innovation, and an openness for outside contact. However, vulnerability and resilience do depend on circumstances.

The same maritime geography that made the Northern Isles accessible to raiders also provided the islanders with the knowledge and skills that the newcomers needed. Islanders knew the anchorages, tides, weather, routes and the neighbouring coasts. They understood where livestock could be obtained, where boats could land safely, which sounds or channels were dangerous, and how to move between islands in poor conditions. Strategic location could make an island a target, but it could also give its inhabitants leverage. The same conditions that produced vulnerability could therefore generate opportunities for negotiation, brokerage, collaboration and entry into the new, exciting maritime networks.

This does not mean that Shetlanders and Orcadians were somehow immune to Viking violence. I have no doubt that raiding, enslavement, killing, displacement and political conquest still remain central to the story. Nor should the idea of ‘islanders are resilient’ simply replace that of the ‘islands are vulnerable’ as another stereotype. I think we are dealing with a methodological point. If we begin by assuming islands host inherently fragile communities, demographic replacement feels completely natural. Instead, if we allow islanders agency and the capacity to adapt, then recruitment, collaboration, selective borrowing and even ethnogenesis become easier to imagine.

I would suggest that the Northern Isles were not simply small pieces of territory onto which a continental model of conquest can be transferred. They were, and are, maritime societies, and their islandness helped shape the encounter.

Can we see this maritime frontier?

If islanders were entering Viking networks before the islands became territorially Norse, and this is not merely a misapplication of Island Studies to Viking Studies, what would we expect to see? Probably not, at first, the things archaeologists are best at seeing. A Scandinavian farmstead is visible. A furnished burial is visible. A house built in a recognisably Scandinavian tradition is visible. But a ship sheltering in a bay for four days leaves nothing tangible. A handful of Scandinavian sailors staying with an indigenous household may leave very little distinctive material behind. A local farmer selling livestock to passing crews remains archaeologically a local farmer. A young Orcadian who joins a Viking crew leaves the islands altogether.

Perhaps some of the apparent archaeological gap in the ninth century exists because we have been looking for the archaeological signature of the tenth.

Simon Buteux’s work at Skaill in Deerness is particularly useful here. He proposed a ‘pioneer stage’ characterised by contact, raiding and trade, perhaps accompanied by winter bases or limited settlement, while Orkney remained predominantly Pictish (Buteux, 1997). This was followed by consolidation, with increasing permanent Scandinavian settlement, and then by a stage in which Norse culture became predominant. Graham-Campbell later regarded the model as having considerable interpretative value (Graham-Campbell, 2003). That’s a relief, because it maps very well on my Vikingisation and Norseisation dichotomy!

The pirate and Island Studies perspectives help fill out what that pioneer stage might actually have involved. I believe it would have required provisioning, exchange, local knowledge, captive movement and relationships with indigenous communities. It may have involved recruitment into Viking crews as well as the beginning of Scandinavian settlement. In that sense, the pioneer stage was not just a chronological waiting room before the ‘real’ Norse settlement began. It may have been a social system in its own right.

Findan fits that model extremely well. His Viking slavers’ ship uses Orkney as maritime infrastructure without telling us anything certain about farms or territorial control. Nearby, after his escape, he eventually encounters a Christian ecclesiastical world connected with Ireland. The precise location of the bishop he meets is uncertain and may have been in neighbouring Pictland rather than Orkney itself, but the broader point remains: Scandinavian maritime activity and an Insular Christian world could exist in close proximity. The sea could change before the land.

Ancient DNA adds another kind of evidence. Margaryan and colleagues analysed Viking-age burials in Orkney, including individuals from Buckquoy and Brough Road, Birsay. Some people buried in recognisably Scandinavian or pagan-style funerary contexts had predominantly British-like rather than Scandinavian ancestry (Margaryan et al., 2020). We cannot simply call them Picts: ancestry is not identity, and they might have come from elsewhere in Britain or Ireland. But the finding does show that Scandinavian cultural affiliation could cross ancestry lines.

That is exactly what the Vikingisation hypothesis, if we can call it that, predicts. A person did not have to possess Scandinavian ancestry to participate in a social world expressed through Scandinavian burial, dress, household affiliation or status practices.

The same point is increasingly visible elsewhere in early medieval Europe. In Anglo-Saxon England, individuals with substantially local British ancestry could be buried in ways conventionally classified as Anglo-Saxon (Gretzinger et al., 2022). Comparable studies of Longobard, Baiuvarian and Avar communities likewise show that culturally or politically named groups could contain people of markedly different ancestry (Amorim et al., 2018; Veeramah et al., 2018; Gnecchi-Ruscone et al., 2025). The details differ, but the lesson is the same: cultural identity and biological ancestry did not map neatly onto one another. Ancestry was not destiny, at least not in all cases.

Slavery provides a more coercive mechanism for the same kind of population mixing. Findan was not simply captured; he was sold and resold. Brink’s work on thraldom underlines how important unfree status was in Viking-age society (Brink, 2021). The later Norman satire Moriuht imagines the same world of capture, transport and sale (McDonough, 1995; Omont, 1894). Captives could be moved through one region into another and eventually become part of new households and communities.

Som new fascinating genetic work shows that movement did not simply run westward from Scandinavia. British- and Irish-related ancestry entered Scandinavian populations during the Viking Age, including individuals in Norway, with a proportionally strong contribution in the north (Rodríguez-Varela et al., 2023; Speidel et al., 2025). Maybe we should not just assume they were slaves. DNA can’t tell us whether these people were captives, spouses, traders or even migrants who had found a new home, but it confirms that the Viking world was circulatory rather than simply colonial.

That is particularly relevant to Orkney and Shetland. Instead of imagining a one-way movement from Norway to the Northern Isles and then onwards to the Hebrides and Ireland, perhaps we should picture a network in which people, goods, information and cultural practices moved in several directions. Instead of just seeing the Northern Isles as mere endpoints of Norwegian colonisation, perhaps they were nodes in a wider seascape.

From Vikingisation to Norseisation

I don’t think we should assume that this means that Scandinavian migration was small or unimportant. Modern genetic work on Orkney and Shetland points to substantial Scandinavian ancestry and to female as well as male migration (Goodacre et al., 2005). Family migration from Scandinavia must remain part of any plausible explanation.

The point is rather that migration entered a world that was already changing. Different islands, and different families within the same island, could have experienced the process in very different ways. One community might suffer violent seizure of land; another might receive substantial Scandinavian settlement; another might initially matter because of a useful harbour; one local elite might resist while another collaborated. However, by the tenth century, however, these different histories could begin to look archaeologically similar.

I think the distinction between Vikingisation and Norseisation is useful. Maritime Vikingisation might begin with the Northern islanders exercising their resilient islander character, overtime participating in raiding, trading, slaving and voyaging networks. Social Vikingisation might involve them adopting Scandinavian burial customs, dress, household affiliation and status practices. Territorial Norseisation came later and went deeper: Norse language, law, landholding, place-naming and political structures became dominant as more Scandinavians moved into the islands. These processes could overlap, but they did not have to happen simultaneously.

We don’t have to see the transition therefore as Picts on one side and Norwegian settlers on the other, followed by a single moment when one population replaced or absorbed the other. It was a changing maritime frontier in which violence, enslavement, migration, collaboration, recruitment, intermarriage and cultural borrowing could all operate at once. A person could be violently enslaved and later incorporated into another community. One local elite might be defeated while another collaborated. Settlers could seize land and subsequently intermarry. Raiders could attack one community and trade with the next. Integration could sometimes be an outcome of violence rather than its alternative.

Seen this way, the transition might move from Pictish island societies through increasing Scandinavian contact, raiding and exchange, seasonal maritime use, slaving and provisioning networks, local participation, Vikingisation, substantial Scandinavian family migration, territorial consolidation, Norseisation and finally ethnogenesis. Different communities would have followed different routes through that process. Complicated! And I think that is the point. Applying Occam’s razor to the interacion of two societies in contact, is too simple, and leads to simple conclusions - peace or war, integration or extermination…

Before the Northern Isles were Norse

So when did the insular Picts disappear? Perhaps there was no single moment, and no one actually noticed until the time Picts or Pettar had become folklore figures. Perhaps the name gradually ceased to describe the social world their descendants inhabited.

Let’s retreat again into the imagination. We have a Norse Viking man marrying, not necessarily just taking, an Orcadian woman. An Irish captive is gven as bride-price, and becomes part of the household. Their neighbours, an indigenous family, enters into the new world-spanning Scandinavian trading and political networks. Their children grow up speaking Norse; their grandchildren have Norse names; they might participate in their family’s Christian communities, or they might not, but they commemorate their dead within an increasingly Norse cultural world. At what point do we stop calling them Picts? Or more to the point, when do they stop calling themselves Picts?

This is what ethnogenesis means. A population can become increasingly culturally homogeneous without ever having possessed homogeneous ancestry. Norse cultural homogeneity may therefore not have existed at the starting point of Viking expansion in the Northern Isles, in sense of an overwhelming early settlement and takeover, but rather it was one of its outcomes.

Let’s return to the two perspectives which I have been discussing. The history of pirate societies shows that maritime raiding depended on shore communities and could recruit people who were not originally part of the raiding population. Island Studies reminds us that islanders are not simply the passive inhabitants of exposed places: their maritime knowledge, networks and adaptive capacities give them agency within new systems.

Of course, the archaeology, texts and genetics do not prove that large numbers of Picts became vikings and then Norse. But I think together they do make the possibility historically serious. Buteux’s pioneer stage gives us a period in which maritime contact could precede territorial Norse settlement. Findan places a slave-carrying Scandinavian ship in ninth-century Orkney. Orcadian aDNA shows people of British-like ancestry participating in Scandinavian cultural traditions. British- and Irish-related ancestry moved back into Scandinavia as well as Scandinavians moving west.

Perhaps, then, the old question - did the Vikings kill the Picts or integrate with them? - has reached the end of its usefulness. We might instead ask when the Northern Isles entered Viking maritime networks; which islanders participated in those networks; who resisted; who collaborated; who was enslaved; who migrated; and how a heterogeneous maritime world eventually became culturally Norse.

The answer was probably different from island to island and family to family. Some people were victims, some migrants, some enslaved, some collaborators, some may have joined Viking crews, some married newcomers, and Scandinavian families arrived in substantial numbers. Out of that mixture emerged a society that none of those groups had brought ready-made with them. However, it was one in whose creation the islanders had exercised agency.

Perhaps the most useful way to approach the early Viking Age, then, is to stop reading it backwards from the Norse world that came afterwards. Before the Northern Islanders became Norse, they may first have become Viking.

This posting traces that story in four movements: what the island’s names tell us about who lived there and how; what archaeologists have recovered; how Bute fits into the wider, hybrid world of the Gall-Gaidheil, the “foreigner-Gaels” of the Irish Sea; and how, when Norway made its last two serious bids for the island in the thirteenth century, the family who held Rothesay Castle rode that crisis all the way to the Scottish throne — and, remarkably, still owns most of Bute today.

Rothesay Castle

Movement 1 - what do the place-names tell us?

The island’s own name – Bute - is a puzzle. Watson and Mac an Tàilleir favour an Old Irish root, bót, meaning “fire,” perhaps recalling beacon or signal fires visible across the Clyde. However, I find this unconvincing. To me it seems like one of the old island names like Skye and Mull, both of which were recorded by Ptolemy in the 2^nd century. Although Bute does not occur in his Geographica, the Ravenna Cosmography (a 7th-century Latin geographical compilation drawing on older, likely Roman-era, source material) records an island called Botis, generally identified by place-name scholars as Bute. This has been analysed by Rivet and Smith, in their The Place-Names of Roman Britain (1979). They suggest that it is root-identical with the Brittonic/Celtic “dwelling” word (the same root that gives Welsh bod, “dwelling, abode,” and is familiar from place-names like Cornish Bodmin or Welsh Bodedern). On this reading, Bute’s name would mean something like “dwelling(s) island” — either describing the whole island as a settled territory or naming it after one particularly prominent settlement on it. Whatever its origins, the Norse who sailed past evidently borrowed the name and called the island Bót. For example, the name turns up in Grettir’s Saga, which relates a story of one group of Norsemen getting into a fight with some others ‘who lay up in winter in the Barra Isles’ and the sea battle took place in narrow straits off Bute.

Two Vikings-Vigbiod and Vestmar were raiding in the Hebrides and plundering in Scotland’s firths. Thrond and Onund went to oppose them and learned that they had sailed in to the island which is called Bute. They took five ships and Onund put them between two cliffs; there was a great channel there which was deep, and ships could sail one way only, and not more than five at a time. Onund made the five ships go forward into the strait in such a manner that they could immediately let themselves drift, with hanging oars, when they wished, because there was much sea-room behind them. There was also a certain island on one side, under it he made one ship lie and they carried many stones to the edge of the cliff, where they could not be seen from the ships. (Grettir’s Saga chap 4).

The chief town, by contrast, is unambiguously Norse. Rothesay derives, on Gilbert Márkus’s reading, from a personal name — Ruðri, later Gaelicised as Ruairidh — attached to Old Norse ey, “island”: Rothri’s isle. Márkus suggests the name was probably coined for the whole island before it narrowed, by the thirteenth century, to describe the castle and the town beneath it, which in Gaelic retained the older and more transparent name Baile Bhòid, “the town of Bute” (Márkus, 2012). It is one of the more striking coincidences in this whole story that Hákonar saga names a ship-captain called Ruðri as the man who, in 1263, pressed a hereditary claim to Bute on Norway’s behalf (see below). Whether that saga Rudri has any connection to the personal name embedded in “Rothesay” two centuries earlier is impossible to prove, but it is a genuinely tantalising echo.

Beyond Rothesay, the map yields a modest but telling scatter of Norse coinages: Ascog, from askr (”ash tree”) and vík (”bay”); Shalunt, from sjár (”sea”) and lundr (”wood” or “grove”); Roseland, from hrossa (”horses”) and land; Birgidale and Dumburgadale, both carrying Old Norse dalr, “valley”; and Corval, containing fjall, “hill.” Even the Gaelic name for the fortified promontory at the island’s south-west tip, Dunagoil — dùn nan gall, “fort of the foreigners” — is itself a memory of the Norse presence, preserved not in a Norse word but in the Gaelic label the newcomers were given.

Dunagoil

What is striking, and what has occupied place-name scholars for half a century, is less what is present than what is absent. In the classic Norse-settled zones — the Northern Isles, the Hebrides, the Isle of Man — the landscape is dense with habitative elements: bólstaðr (”farmstead”), setr (”shieling” or dwelling), staðir (”homestead”). These are the names of places that Norse-speaking communities founded, subdivided, and lived in generation after generation. On Bute, as on neighbouring Arran and Kintyre, such names are entirely absent. What survives instead is almost exclusively topographical — dalr, vík, fjall — the vocabulary of people describing a landscape rather than founding a lineage of farms within it.

W. F. H. Nicolaisen, writing in the 1970s, took this absence at face value: for him it meant that Norse speakers on the Argyll coast were essentially passing through, leaving what he memorably called “onomastic graffiti” rather than settling in numbers (Nicolaisen, 1976). Gilbert Márkus, building on the work of myself and Arne Kruse on the wider Gall-Gaidheil zone, has offered a more interesting reading. Rather than reading the absence of habitative names as evidence of thin, transient contact, Márkus argues it is evidence of settlement that was both real and remarkably short-lived in linguistic terms — Norse-speaking families did arrive and did settle Bute in the primary phase of colonisation (hence the topographical layer), but they, or their children, had shifted to speaking Gaelic so quickly that by the time farms were being subdivided and new settlements named — the stage at which habitative names normally proliferate — the naming was already being done in Gaelic (Márkus, 2012; Jennings and Kruse, 2009). Ascog is the textbook case: a primary Norse-named farm (askr-vík) later split into Kerrycroy, Kerrycrusach, and Over, Nether and Mid Ascog — Gaelic and Scots names layered onto a Norse core, exactly the pattern the theory predicts. In addition, Crawford makes the case that the name Langal at the south end of the island near Kingarth — a name she identifies as cognate with Langal/Langwell names found across northern Scotland, deriving from Old Norse lang-völlr, “long field or level plain,” a description that, she notes, “appears to describe the area very well” (Crawford, 2012, p.36). Crucially, Langal was not a passing description: it was originally a substantial estate of twelve merks, later divided into two farms that carry Gaelic suffixes today. Crawford’s argument is that völlr names of this kind were doing the job that bólstaðr, setr and staðir normally do elsewhere — functioning as genuine farm-names.

The comparison with the Hebrides and Man sharpens the point. Where those island groups retained Norse speech and dense Norse toponymy for centuries, Bute — sitting in the inner, more sheltered waters of the Firth of Clyde, closer to the political gravity of Gaelic Argyll and Strathclyde — shows a thinner Norse layer that was rapidly overwritten. Even so, Crawford is emphatic that what survives on Bute is not negligible: “there is a still-surviving stratum of Old Norse topographical names in Bute which can be used to provide evidence of the establishment of Norse speakers and land-owners” (Crawford, 2012, p.36).

Movement 2 – what does the archaeology tell us?

Place-names describe a linguistic event. Archaeology, when it survives, can describe a material one — and on Bute it does, unevenly but suggestively, add to the picture that Norse-speaking people were not just passing offshore but living, dying, and worshipping on the island.

As yet, unlike Arran, no Viking grave has been securely identified. However, the Drumachloy sword-hilt, recovered near Ettrick Bay and now in Bute Museum, might have come from a grave. It has a Norwegian-type hilt, damaged and corroded, its pommel lost, with 1977 X-rays revealing a probable chequerboard inlay of copper or silver alloy. Crawford treats this as “probably from a Norse grave,” noting that “it is unusual for a sword hilt of that quality to be found in a context other than in association with a pagan grave,” and cites F.T. Wainwright’s observation that “warriors do not leave their swords casually in barns or byres, nor do they throw them on middens” (Crawford, 2012, p.36, n.5, citing Wainwright, 1955, p.152). No grave has actually been excavated around the find, so this remains an inference rather than a confirmed burial — but it is the strongest inferential case on the island.

Drumachloy Sword Hilt

At the impressive site of Little Dunagoil, on the same promontory as the early church site of St Blane’s, whose Gaelic name records “the fort of the foreigners,” excavations in the 1960s uncovered two large rectangular buildings interpreted at the time as Norse longhouses, together with a probable Norse comb fragment and a weight of Scandinavian character (Marshall, 1964). However, a later settlement survey has urged caution: the “longhouses” are structurally ambiguous and their Norse attribution not securely established (Isle of Bute Settlement Survey, 1999). Nonetheless, the comb and weight do suggest the site was inhabited in the Norse period. More recently, at Cnoc an Rath, in the Borgadale valley, archaeologist Paul Duffy has obtained radiocarbon dates from a buried surface falling in the late seventh to late ninth centuries — squarely within the period of Viking activity in Argyll — and has proposed, more speculatively, that the mound may be a Norse assembly or thing site, conceivably even connected to the historically attested Gall-Gaidheil leader Ketill Flatnose (Duffy, in Ancient Origins, 2015). This remains a hypothesis rather than a settled finding: the radiocarbon evidence is consistent with a Norse date, but it does not by itself demonstrate an assembly function.

The Hostage Stone

Finally, there is the small island of Inchmarnock, off Bute’s western shore. It was an early monastic site, and has produced what is probably the most evocative single artefact in the whole story: the so-called Hostage Stone, an incised slate apparently depicting a bound figure, apparently a monk, being led towards a boat by a figure in chainmail — widely, though not universally, read as a depiction of a Viking raid on the monastery (Lowe, 2008). I am unable to see the chain that supposedly binds the monk to the warrior, so perhaps I need the eye of faith! Personally, I prefer, the other important stone from Inchmarnock, a rune-inscribed cross, which commemorates someone called Guðleif or Guðleik. Who was he and why was he commemorated at this monastic site? Was he a native of Bute, or might he have been a member of King Hakon’s invasion fleet?

Archaeologically, Bute’s Norse remains are modest: a probable but unproven sword-grave, an ambiguous longhouse site with one certainly Viking curated object, the Hostage Stone, and a rune-stone. Crawford’s own verdict is the fair one: “this evidence may be thin and scattered and unimpressive on its own but when all is added up — the archaeology, the place-names, the runestone and the saga reference — it suggests that Bute was very much part of the Viking world, even if that world became rapidly Gaelicised in the tenth century” (Crawford, 2012, p.37).

Movement 3 - Bute among the Gall-Gaidheil

The archaeology and the place-names describe a local, material reality. But Bute’s significance in the Viking Age is best understood at a wider, regional scale: as part of the world of the Gall-Gaidheil, literally “foreigner-Gaels,” the hybrid Norse-Gaelic population and political culture that came to dominate western Scotland and the# Clyde estuary from the ninth century onward. The Gall-Gaidheil were the product of exactly the process the place-names imply — Scandinavian settlers intermarrying with, and assimilating the language and Christianity of, the Gaelic-speaking populations of the Inner Hebrides, and the western coasts. Their name survives directly in Galloway (Gall-Ghaidhealaibh, “among the Gall-Gaidheil”).

Bute’s place within this world is not a matter of inference alone; it is directly attested. The early Irish Martyrology of Tallaght, compiled around AD 900, records St Blane, bishop of Kingarth on Bute, as belonging “in Gall-Ghàidheil” — an explicit ninth- or tenth-century statement locating Bute within Gall-Gaidheil territory (Márkus, 2012). The Félire Óengusso makes a similar association. This is a rare thing in the Viking Age documentary record of the west of Scotland: a specific, named, dateable text placing a specific island inside the political-cultural geography of the Gall-Gaidheil, rather than leaving historians to reconstruct that geography from silence and topography alone. Bute, given its fertility and strategic geographical position, might in fact have been the heartland of Gall-Gaidheil territory.

Bute’s ecclesiastical history in the twelfth century reinforces this sense of the island’s regional importance long after any “Viking Age” proper had ended. When the archdiocese of Nidaros (Trondheim) was created in 1152–3, the diocese of the Hebrides — Suðreyjar, or Sodor — was placed under it, formalising a Norwegian ecclesiastical claim over the Hebridean church (Crawford, 2012, pp.41–42, citing Beuermann, 2002). Within that diocese, distinct regions appear to have clustered around their own principal churches, to which a bishop based at Peel in Man would pay occasional visitations: Snizort in Skye and Rodel in Harris for the northern Hebrides, Iona as the diocese’s most important spiritual centre overall, and — in the Clyde estuary — Kingarth in Bute (Crawford, 2012, p.41, citing Woolf, 2003, pp.180). Bute, in other words, was still functioning as one of only four recognised regional ecclesiastical centres of the entire Hebridean diocese in the mid-twelfth century, three centuries after the first Norse settlers are likely to have arrived.

Political control of the hybrid world of which Bute was part, kept changing hands. In the twelfth century the Kings of Man, were in competition with Somerled. After the Battle of Epiphany in 1156, the Kingdom of the Isles was split between Somerled and King Godred of Man — an event the Manx chronicler blamed for the kingdom’s ruin — with Somerled and his sons controlling the southern Hebrides south of Ardnamurchan, “possibly including Arran and Bute” (Crawford, 2012, p.42, citing McDonald, 1997, p.56). Crawford is honest that the sources do not settle Bute’s exact allegiance in this period. However, what is not in doubt is that the island’s strategic value meant the both the Kings of Man and Somerled and his heirs would have wanted to possess it. At the same time, we must not forget though that both competing forces owed allegiance to the Kings of Norway, who since the 1090s had been overlords of the Hebrides. Bute was about to fall out of the Norwegian king’s orbit and into the hands of the Stewarts.

Movement 4 – Stewart encroachment and Norwegian campaigns

The Stewart claim to Bute did not arrive out of nowhere in 1200; it can be dated with unusual precision to a specific documentary act. Crawford points to Alan fitz Walter’s grant, made before 1204, of Kingarth with its lands and chapels to Paisley Abbey — the Stewart family’s own monastic foundation on the Clyde — as clear evidence of “the Stewart family’s attempted extension of power over the Clyde from Renfrewshire to the island of Bute” (Crawford, 2012, p.44). The grant, tellingly, “seems never to have been implemented” (Crawford, 2012, p.44, n.8) — a sign that Stewart ambition on Bute in 1200 was running ahead of Stewart control on the ground. Alexander II mounted a royal campaign in the area in 1222 which was “possibly aimed at royal control of Arran and Bute” (McDonald, 1997, p.84, cited in Crawford, 2012, p.44), and by 1230 Scottish . Stewart position had solidified enough that a Scottish garrison held Rothesay Castle (Crawford, 2012, p.44) — the target that year of the Norwegian-backed assault traditionally associated with Uspak (Óspak-Hákon), recorded in Hákonar saga as the earliest known account of an assault on a Scottish castle, in which the Norse are said to have hewn through the castle’s soft stone wall with axes before withdrawing, Uspak dying of his wounds soon after.

There was a much larger Norwegian assault in 1263.While King Haakon’s fleet lay at Gigha — the saga’s Guðey — he detached ships to Bute “to meet those who had been sent thither.” Among the Norwegians was a ship-captain named Ruðri (see above), who believed he had a hereditary claim to the island; his name suggests, that he may have belonged to the MacSorleys, the descendants of Somerled (Crawford, 2012, pp.44–45, n.10). Having failed to win the island back from the Scots by his own means, Ruðri and his two brothers swore allegiance to King Hákon. What followed was a skirmish at “the castle” — presumably Rothesay — in which Rudri killed nine men, after which the island passed under Norwegian control; the Norwegian court poet Sturla Þórðarson later commemorated the reconquest of “broad Bute” from its Scottish holders in verse (Crawford, 2012, p.45).

Bute then became briefly a Norwegian forward base, from which Ruðri’s men harried the nearby Scottish coast, prompting the Scots to open negotiations, met by a Norwegian embassy sent to King Alexander at Ayr. Those talks collapsed over one specific, named sticking point: Hákon’s claim to all the isles, which Alexander refused to concede where it touched the Clyde islands by name — recorded in the saga as Bot ok Herrey ok Kumreyjar, “Bute and Arran and the Cumbraes.” Neither king would yield these three islands, and it was this deadlock, probably more than any other single issue, that broke the negotiations down (Crawford, 2012, p.45). Hákon then sailed his fleet directly into the Clyde and anchored under the Cumbraes in open defiance of Alexander’s authority. While anchored there, he detached sixty ships under King Magnus of Man and the MacSorley brothers Dougal and Alan to raid up Loch Long and across the Tarbert portage into Loch Lomond, “and wrought there great damage” — a raid that inflicted real destruction but did nothing to resolve the deteriorating position of the main fleet in the Clyde, which autumn storms had already begun to batter before the skirmishing at Largs on 2 October (Crawford, 2012, p.45). After the inconclusive encounter there, Hákon’s fleet withdrew north, reached Orkney by 29 October, and settled in to overwinter — a decision cut short by the king’s death that December, which effectively ended Norwegian political ambitions in the west.

Norse attacking Rothesay Castle

The Treaty of Perth, concluded on 2 July 1266 between Hákon’s peaceable successor Magnus “the Law-mender” and the Scottish crown, formalised what the Largs campaign had already made practically inevitable. Framed almost as a sale — the Hebrides and Man ceded to Scotland in exchange for four thousand merks and a perpetual annual payment of one hundred merks — the treaty also protected Hákon’s former supporters from reprisal, allowing them to stay or leave “with their goods, lawfully, freely, and in full peace” (Donaldson, 1970, p.35, cited in Crawford, 2012, p.46). Rothesay Castle’s unique circular curtain wall, still stands as a mute witness of this warlike clash between the Kings of Norway and Scotland.

The Stewarts: from frontier keepers to kings, to landlords still

It would be easy, telling this story, to treat 1266 as the natural endpoint in Bute’s interesting history — Norway defeated, the frontier closed, the Gall-Gaidheil chapter of Bute’s history over. Indeed, it was the endpoint for the Norse era of Bute’s history. However, even someone like me with a particular interest in the Viking period, the later History of Bute is also fascinating. The Stewart (later Stuart) era was just beginning, and in a sense, it continues to this day.

The Stewarts descended from Walter fitz Alan, a Breton-Norman adventurer who arrived in Scotland under David I and was made hereditary Steward — dapifer — of the Scottish crown around 1150; the office title eventually hardened into the family surname. His son Alan, second High Steward, acquired Bute around 1200, as we have said, and either he or his son Walter, the third High Steward, built the circular stone castle at Rothesay that would twice withstand — and twice briefly fall to — Norwegian assault. The family’s fortunes rose sharply during the Wars of Independence: Walter, sixth High Steward, married Marjorie Bruce, daughter of Robert the Bruce, an alliance commemorated in the Bute Mazer, a maple communal drinking bowl made around 1314–1327, its silver-gilt central boss showing a recumbent lion representing Robert I encircled by the shields of six of his chief supporters, with the Stewart arms set between the lion’s paws.

When David II died childless in 1371, the crown passed to Marjorie and Walter’s son, who became King Robert II, the first monarch of the House of Stewart. Rothesay Castle, the frontier fortress that had absorbed two Norwegian sieges, became a royal residence; Robert III would die there in 1406. Robert III gave his heir the title Duke of Rothesay — the first dukedom created in Scotland — and that title, remarkably, is still borne by the heir to the British throne today, a six-hundred-year-old survival that ties the modern monarchy directly back to the Norse wars fought for possession of this one small Clyde island.

The family that still owns much of Bute today descends not from the royal line itself but from a collateral branch: Sir John Stewart, known as “the Black Stewart,” an illegitimate son of Robert II, who by a charter of 1400 was made hereditary Sheriff of Bute, with his descendants later confirmed as hereditary keepers of Rothesay Castle. Ennobled steadily over the following three centuries — Nova Scotia baronets from 1627, Earls of Bute from 1703 — the family reached its greatest prominence with John Stuart, third Earl of Bute, tutor and confidant of George III, who served as Prime Minister of Great Britain from 1762 to 1763. His son became the first Marquess of Bute in 1796, and through a marriage to the Crichton heiress of the Earls of Dumfries the family took the compound surname Crichton-Stuart still in use today. The second Marquess built his fortune on the Cardiff docks and the coal seams of Glamorgan; the third Marquess, one of the wealthiest men in Victorian Britain, used part of that fortune to rebuild Mount Stuart House on Bute as a lavish Gothic Revival palace — reputedly the first house in Scotland fitted with purpose-built electric lighting and an indoor heated pool — and to restore both Rothesay Castle and Cardiff Castle.

Mount Stuart

That wealth, channelled through the modern Mount Stuart Trust, a charitable trust established in 1985, is the mechanism by which the family’s landholding on Bute persists into the present. By the Trust’s own account it remains custodian of some eighty-seven per cent of the Isle of Bute, of which it directly manages around sixteen per cent, the remainder held through long-term tenancies and partnerships — including, since 2020, new agricultural leases bringing six farming families to the island. The Gazetteer for Scotland records the wider Bute Estate as extending to roughly 10,900 hectares, comprising, per Scottish Land & Estates, some thirty-six farms, around a hundred residential properties and substantial woodland. Mount Stuart House itself, opened to visitors since the 1990s, remains the island’s principal tourist draw, and the current head of the family, John Bryson Crichton-Stuart, eighth Marquess of Bute (succeeded 2021), holds — in an unbroken line running back to the Black Stewart’s 1400 charter — the hereditary keepership of the castle that once withstood the Norwegian fleets, though the castle itself has been in state care, now under Historic Environment Scotland, since 1961.

Coda

There is something fitting, if largely accidental, about the fact that the family now most associated with Bute is itself descended from the very Stewarts who were granted the island precisely because it was a contested frontier. The family whose ancestors held Rothesay castle against Haakon’s fleet. Bute is a small island. But as a case study in what happens when Norse and Gaelic worlds meet, fuse, and are fought over, it is very hard to improve upon.

My name is Andrew Jennings, and my paper today is called Hebrideans... Weirdos! — which I hope gives you a sense of both the subject matter and the tone I’m aiming for. It’s a title that comes directly from the sagas themselves, in a way, because the Hebrideans in Old Norse literature really are treated as a rather suspicious and peculiar bunch.

What I want to do over the next forty minutes is explore why that is — what it tells us about how medieval Icelanders thought about cultural mixing, proximity, and the boundaries of their own world. We’ll be looking at sorcerers, revenants, people with catastrophically destructive eyes, and some seals. So I hope you’ll find it an enjoyable journey.

Right — let’s begin.

I. Introduction: The Liminality of the Suðreyjar

In this paper I will examine the representation of Hebridean figures in the Icelandic saga corpus, focusing on how these characters embody deep-seated anxieties concerning cultural hybridity and the boundaries of the Norse world.

Drawing on the “gradations of familiarity” framework established by Catriona Ellis, in her 2020 paper ‘Degrees of separation: Icelandic perceptions of other Scandinavian settlements’, I argue that by the thirteenth century the Hebridean (suðreyskr maðr) had evolved into a distinct and dangerous literary type, characterised by associations with aggressive magic, unregulated violence, and uncanny transformations — specifically the recurring motif of the seal-human hybrid.

The medieval Icelandic worldview was not a simple binary of “Self” and “Other,” but rather a sophisticated spectrum of cultural proximity. As Catriona Ellis (2020) has demonstrated, Icelandic perceptions of the Norse diaspora were structured through what she terms “gradations of familiarity.” In this mental geography, Norway and the Northern Isles (Orkney and Shetland) occupied a “lateral axis” of relative continuity — regions that were culturally, linguistically, and legally intelligible to the Icelandic mind. These were the lands of ancestors, the sources of law, and the targets of legitimate trade. The Shetlanders (Hjaltlendingar), for instance, are never portrayed as “Other,” despite one bearing the nickname bakrauf, “arsehole.”

The Hebrides — the Suðreyjar or “Southern Isles” — occupied the far more ambiguous position of a “vertical axis,” connecting Iceland with the Hebrides and Ireland. Situated at the confluence of the Scandinavian and Gaelic worlds, the Hebrides were neither wholly external nor comfortably internal to the Norse cultural sphere. They existed within a liminal zone of hybridity, where Norse identity was perpetually entangled with, and transformed by, Gaelic influences.

I would like to argue that the saga corpus reflects a growing anxiety regarding this cultural hybridity. As direct contact declined in the later medieval period, the Hebridean emerged as a powerful literary trope: the “Near Other.” Unlike the “Distant Other” of the Sami (Finnar) or the Native Americans (Skrælingar), whose difference was geographically and culturally remote (Athanasiou 2024), the Hebridean was a figure of unsettling proximity. They bore Norse names, shared settlement histories, and moved within the same maritime networks, yet they carried with them what can be termed the “contagion” of the foreign — specifically in the form of Gaelic magic and antisocial behaviour.

II. The Hebrides and the Norse Diaspora

In the early phases of the Viking Age, the Hebrides were integral to the Norse Atlantic network. Archaeological, historical, and literary evidence all point to sustained contact between Norway, the Northern Isles, the Hebrides, and Ireland. The settlement of Iceland itself was closely connected to these movements, with Landnámabók preserving numerous references to settlers with Hebridean associations.

Among the most prominent figures is Auðr the Deep-Minded, daughter of Ketill Flatnose, who is associated with the Hebrides and plays a central role in Icelandic settlement traditions. Her story is significant because it highlights the Hebrides as a site of cultural transmission. According to Landnámabók, Auðr had adopted Christianity in the Hebrides prior to her arrival in Iceland, raising crosses and practising private devotion — a detail that frames the Hebrides not as peripheral but as a conduit for religious and cultural exchange within the North Atlantic world. In her train were several Hebridean figures: her brother Helgi bjólan, her nephew and foster-son Örlyggr Hrappson, who founded and dedicated a church to Columba, her great-nephew Ketill inn fíflski “the Foolish” (so named for his Christian belief), and her grandson Óláfr feilan. All must have been conspicuous as Christians in a pagan milieu; Helgi and Óláfr apparently bore Gaelic saints’ names as nicknames.

Further evidence of Hebridean participation in Norse expansion is found in the figure of Grímr Kamban, whose Gaelic nickname means “shinty stick” or “little bent one,” and in the anonymous poet of Hafgerðingadrápa, described explicitly as a suðreyskr maðr. Composed during a voyage to Greenland, the poem invokes divine protection and is notable not only for its Christian content but for its geographical context, situating a Hebridean within the wider movement of Norse Atlantic expansion.

The anonymous poet was not the only Hebridean to visit Greenland. According to Eiríks saga rauða, when Leifr is driven off course to the Hebrides, he has an affair with a noblewoman of unusual gifts, called Þórgunna, which results in the birth of a son, Þorgils. Leifr refuses to elope with her, and she warns that he is unlikely to enjoy having his son — but that the boy will eventually follow his father to Greenland, which in due course he does. The saga’s comment on Þorgils is pointed: “there seemed to be something uncanny [or weird] about him all his life.” This remark anticipates the wider literary pattern in which the Hebridean ceases to be a noble ancestor, like Auðr the Deep-Minded, and becomes instead something weird, aggressive, and antisocial.

To understand why this literary stereotype crystallises in the thirteenth century, it is necessary to consider what was actually happening to the political relationship between the Norse world and the Hebrides during the period in which the sagas were being composed.

In the ninth and tenth centuries, the Hebrides had been thoroughly integrated into the Norse Atlantic network. Norse settlement was substantial, Norse lordship was exercised, and the movement of people, goods, and ideas between Iceland, the Northern Isles, the Hebrides, and Ireland was continuous and largely unremarkable. However, there was also an extensive period of cultural mixing and Gaelicisation of the Norse Hebridean community.

From the eleventh century onwards, however, the political situation in the Hebrides became increasingly unstable and contested. The islands passed in and out of effective Norse control, subject to the competing pressures of the Kingdom of Norway, the Scottish crown, and local Hebridean lordships. The Battle of Largs in 1263, in which a Norwegian expedition under King Hákon Hákonarson failed to reassert Norse authority in the western isles, proved the decisive turning point. The subsequent Treaty of Perth in 1266 formally transferred sovereignty over the Hebrides — and the Isle of Man — from Norway to Scotland. After 1266, the Hebrides were, in political terms, no longer part of the Norse world at all.

The significance of this chronology for the saga corpus is considerable. The major sagas dealing with Hebridean figures — Laxdæla saga, Brennu-Njáls saga, Eyrbyggja saga, and Vatnsdæla saga — were all composed in the thirteenth century, precisely during the period in which Norwegian sovereignty over the Hebrides was being challenged and ultimately lost. The Hebrides were slipping away from the Norse imaginative world even as the sagas were being written. This context helps to explain both the intensity of the literary stereotype and its particular character. The Hebridean in the sagas is not simply a foreign figure but a formerly familiar one — a part of the Norse world that was in the process of becoming irrecoverably other. The literary construction of the dangerous, hybrid Hebridean may therefore be understood in part as a response to a real historical process of estrangement: the sagas were, among other things, working through the cultural and imaginative consequences of a world that was contracting.

It is also worth noting that the sagas were composed in Iceland at a moment of acute internal political instability. The Sturlung Age — roughly 1220 to 1264 — was a period of violent civil conflict between powerful Icelandic chieftain families, culminating in Iceland’s submission to Norwegian sovereignty in 1262–64. Anxieties about identity, loyalty, social order, and the fragility of law were not merely abstract concerns for thirteenth-century Icelandic authors: they were lived political realities. The figure of the Hebridean — characterised, as we will see, by refusal to pay compensation, violation of social bonds, and resistance to the frameworks of order — may have carried particular resonance for audiences who were experiencing precisely those failures of social order at first hand.

III. Magic and the Hebridean Stereotype

The most consistent and defining feature of Hebridean representation in the Icelandic sagas is an association with the supernatural, and with magic — particularly seiðr. In Old Norse sources, this form of sorcery is framed as morally ambiguous, socially disruptive, and unmanly (ergi) when practised by men.

The most developed example of this supernatural connection is found in Laxdæla saga, in the account of the Hebridean family of Kotkell. The saga introduces them in explicitly marked terms: “These people had come from the Hebrides. They were all extremely skilled in witchcraft (mjök fjölkunnig) and were great sorcerers... their presence there was not well liked.” Their identity as Hebrideans is inseparable from their role as practitioners of dangerous, socially destabilising magic. Accused of both sorcery and theft, their presence is described as making life “unbearable” — a combination of criminality and supernatural power that reinforces their position as outsiders operating beyond accepted norms.

The most dramatic demonstration of their power is the storm episode. In response to legal action taken against them, Kotkell and his family construct a seiðhjallr — a ritual platform — and perform incantations against their enemy Þórðr Ingunnarson. As the saga says:

“Kotkel erected a large seiðhjallr, and they all climbed onto it; there they chanted potent incantations — these were magic spells. And presently a tempest arose.”

This storm is not a natural phenomenon. It is explicitly directed violence: Þórðr “realized that the storm was directed against him.” The result is catastrophic — a wave strikes the ship where no wave had ever struck before, and Þórðr and all his companions are drowned.

In a later episode, the family perform seiðr from the roof of a house, as the saga says:

“They climbed on to the roof of Hrút’s house and made great incantations there... sweet was the singing they heard.”

The apparent beauty of the sound is deceptive. The enchantment draws its victim, Hrút’s twelve-year-old son Kári to his death:

“He began to feel very restive, and eventually he got up and went to look outside; he walked into the seiðr and fell down dead at once.”

He is not attacked physically; he is drawn to his death through enchantment.

As well as practising seiðr, Kotkell’s sons possessed the evil eye. One of them, Hallbjörn, bore the epithet slikisteinsauga — “sleekstone eye,” referring to a tool used in flattening cloth, a traditionally female sphere of labour that reinforces the theme of unmanliness associated with male sorcerers. On being executed, he turns his gaze back towards the land and delivers a curse:

“It was not a lucky day for our family when we came to this Kambsness... And now I lay this curse, that Þorleikr will enjoy little happiness there from this day on, and that all his successors at Kambsness will inherit nothing but trouble there.”

This curse is noted by the saga to have been very effective.

His brother Stígandi possesses a gaze so malignant it is practically a biological weapon. When he was captured and a bag placed over his head, a tear in the bag allowed him to glimpse the hillside opposite and “suddenly it was as if a whirlwind came and turned the whole sward upside down, so that no grass has ever grown there since.” This trope resonates strongly with the Gaelic mythological tradition of Balor of the Fomorians, the malevolent cyclops whose gaze brought fire and destruction — a parallel to which I return in the postscript. Hallbjörn’s body was washed ashore but, once buried, he did not rest quietly in his grave. He became the first of this paper’s three Hebridean draugar — revenant, walking dead.

IV. Violence and the Breakdown of Social Order

Alongside magic, Hebrideans in the saga corpus are consistently associated with violence that is not merely frequent but structurally disruptive — violence that undermines the social and legal frameworks upon which Icelandic society depends.

The most developed example is the figure of Þjóstólfr in Brennu-Njáls saga. He is “a Hebridean by descent” and the foster-father of Hallgerðr “Long-legs.” He is introduced in terms that immediately emphasise both his physical power and his moral deviation: “He was a strong man and a great fighter; he had killed many men and paid compensation for none.” His very name is derived from þjóstr, meaning fury. The refusal to participate in the system of compensation (bætur) is critical. Within the saga world, violence is not in itself aberrant, but it is expected to be contained within a framework of law, negotiation, and restitution. Þjóstólfr’s conduct represents a structural rejection of this framework.

His violence is also marked by deliberateness and intensity. Acting as an enforcer on behalf of Hallgerðr, he murders her first two husbands not as part of a feud governed by escalating obligation, but as targeted acts of elimination. In one instance, he pursues Þórvaldr across a considerable distance by sea, rowing alone until he overtakes him:

“Þjóstólfr rowed after him until he came up with him, and then he struck him with his axe and split him down to the shoulders.”

When he kills again, the violence is once more direct and unrestrained:

“He dealt him his death-blow at once, and it is said that he laughed when he struck.”

The detail of laughter is particularly striking. It signals not merely violence but a detachment from the moral gravity of the act, emphasising his position outside the ethical norms of the Icelandic Commonwealth. Þjóstólfr’s role is therefore not that of a conventional feud participant but of a destabilising force — an individual whose actions accelerate conflict while bypassing the mechanisms designed to contain it.

This pattern finds a parallel in the figure of Svartr in Vatnsdæla saga, described as “big and strong, unpopular and contrary.” Svartr’s defining act — killing a man after residing with him over winter — constitutes a profound violation of hospitality, one of the foundational social bonds in the saga world. Here, as with Þjóstólfr, violence is not simply physical but structural, directed against the norms that sustain social order.

Taken together, these figures establish a clear pattern. Hebridean violence in the sagas is deliberate rather than reactive, unregulated rather than compensatory, and socially corrosive rather than contained. In this sense, these figures function as agents through which the sagas explore the limits of order — exposing the fragility of a system dependent upon restraint, negotiation, and mutual recognition.

V. Death, Haunting, and the Uncanny

Let’s return to the draugar, the revenant walking dead. The association of Hebrideans with violence and the supernatural reaches its fullest expression in the motif of the revenant. It is here that the concept of hybridity moves from the cultural to the ontological. The Hebridean figure becomes a being inhabiting the boundary between life and death, and between human and animal.

Laxdæla saga provides the chilling example of Víga-Hrappr (Killer-Hrapp), explicitly marked as culturally mixed: “Scottish on his father’s side... whereas all his mother’s family came from the Hebrides,” having himself been “born and brought up there.” This is not incidental detail. It situates Hrapp precisely within the hybrid Norse-Gaelic milieu that generates unease in Icelandic narrative tradition.

In life, Hrapp already embodies the traits associated with the Hebridean stereotype. He is “a big, strong man who would never yield to anyone... and refused to pay compensation for his misdeeds.”

His behaviour intensifies over time: “He became more and more brutal; he molested his neighbours so relentlessly that they could scarcely hold their own against him.”

Yet it is in death that Hrapp becomes truly significant. On his deathbed, he gives extraordinary instructions:

“When I am dead I want my grave to be dug under the living-room door, and I am to be placed upright in it under the threshold, so that I can keep an even better watch over my house.”

Burial in a liminal architectural space — neither fully inside nor outside — perfectly reflects Hrapp’s symbolic position. He is a threshold figure, and his refusal to remain “dead” or “buried” is a physical manifestation of his refusal to abide by social or natural boundaries.

The consequences are immediate:

“Difficult as he had been to deal with during his life, he was now very much worse after death, for his corpse would not rest in its grave; people say he murdered most of his servants in his hauntings after death, and caused grievous harm to most of his neighbours.”

His body is eventually exhumed and relocated, yet the consequences persist. His son, who attempts to inherit the property, “went mad, and died soon afterwards.” Further deaths follow, including the drowning of Þórsteinn the Black and his party as they approach Hrapp’s abandoned settlement. Significantly, this episode introduces another uncanny element:

“Throughout the day they saw an enormous seal swimming in the current; it circled the boat all day. It had huge flippers, and everyone thought its eyes were those of a human. Þórsteinn told his men to harpoon the seal, but all their attempts failed.”

The implication is that Hrapp’s agency persists in this altered form.

Alongside Víga-Hrappr, the figure of Þórgunna, in Eyrbyggja saga provides a complementary example of the Hebridean association with the uncanny and the restless dead. She arrives in the year 1000 on a ship from Dublin whose crew came from Ireland and the Hebrides, and is invited to stay at the farm at Fróðá. She is physically imposing — “a massive woman, tall, broad-built, and getting very stout... hard to get on with and wasted little time on conversation” — and, like Hrapp, socially marginal despite being physically present. She goes to Mass every morning but remains distant from her hosts. She is probably the same Þórgunna mentioned previously who wanted to elope with Leifr.

Before her death at Fróðá, a striking omen occurs during haymaking: a sudden storm brings a shower of blood that falls on the farm. Everything dries afterwards — except Þórgunna’s hay and rake. When Þóroddr, the farm’s owner, asks what the omen means, she replies: “Most likely it forebodes the death of someone here.” Indeed, it foretells her own.

On her deathbed, she gives detailed instructions regarding her burial and possessions, including a critical warning: “My bed and all its furnishings I want burnt to ashes... I wouldn’t like to be responsible for all the trouble people will bring on themselves if they don’t respect my wishes.” Her instructions are ignored, and terrible consequences rapidly unfold.

While her corpse is being transported by Þóroddr and his men to Skálholt for burial, the party stops at a farm whose stingy owner refuses them food. That night, her revenant corpse is seen in the larder: stark naked, preparing a meal. She carries the food into the living room, lays the table, and serves it. When the farmer then makes the party welcome, she walks out and does not reappear. She is eventually buried at Skálholt, but because her warnings about her bed-furnishings were not heeded, a series of supernatural events unfold at Fróðá — the most famous hauntings in saga literature. Among these is the appearance of a seal’s head rising through the floor of the living room, followed by its flippers, turning its eyes towards the canopy from Þórgunna’s bed. According to the saga:

“One of the farm-hands came up and started hitting the seal, but it kept rising further up with every blow, until its flippers emerged. At that the man fainted, and everyone was paralyzed with horror, except for young Kjartan, who rushed up with a sledge-hammer and struck the seal on the head. It was a powerful blow, but the seal only shook its head and gazed around. Kjartan went on hammering the head and driving it down like a nail into the floor till the seal disappeared, then he flattened out the floor above its head.”

The recurrence of the seal motif across two separate sagas demands closer attention than it has typically received. In both cases, the seal appears at a moment of transition: it follows the death of a Hebridean figure whose agency has persisted beyond the grave, and it manifests in a form that is simultaneously animal and uncannily human. In Laxdæla saga, the seal with human eyes circles the boat that will carry Þórsteinn the Black to his death near Hrapp’s farm. In Eyrbyggja saga, the seal’s head rises through the floor of the living room at Fróðá, turning its gaze towards the bed-canopy that Þórgunna had warned must be destroyed. In both instances, the seal does not act directly — it watches. Its function is to signal, to witness, and perhaps to preside. It is the presence of something that has crossed a boundary and cannot, or will not, cross back.

The choice of the seal is not arbitrary. The seal is, in biological and cultural terms, precisely a liminal creature — one that inhabits the boundary between land and sea, between the familiar and the unknown. In the Norse and Gaelic worlds alike, the sea was the realm of the unpredictable, the dangerous, and the supernatural. The seal, which moves between that realm and the human world of the shore, was a natural folkloristic metaphor for characters that similarly moved between categories: the living and the dead, the Norse and the Gael.

When the saga authors placed seals at the threshold moments of their Hebridean narratives, they were therefore not simply reaching for a convenient image of the uncanny. They were drawing on a living imaginative tradition in which the seal already carried precisely the symbolic freight the narrative required: liminality, transformation, the persistence of identity across categorical boundaries, and the specific hybridity of the Norse-Gaelic world. The Hebridean draugr who manifests as a seal is not becoming something alien. He or she is becoming something that was always already implicit in the cultural logic of Hebridean identity — a creature of two worlds, belonging fully to neither, watching from the threshold with eyes that everyone knew were human.

In Þórgunna and Víga-Hrappr we have two socially disruptive Hebrideans who become draugar after death and who appear, in some form, to become seals. Alongside the stories of Kotkell and his family, we also have three drowning events associated with Hebrideans — because after Þórgunna’s burial and the seal incident, Þóroddr and his men are all drowned and take to haunting Fróðá in turn.

VI. The Heroic Exceptions: Kári Sölmundarson, Álfgeir, and the Limits of the Hebridean Stereotype

Amid the recurring portrayal of Hebrideans as hybrid agents of magic, violence, and social disruption, the figure of Kári Sölmundarson in Brennu-Njáls saga stands as a striking and deliberate exception. Introduced explicitly as ór Suðreyjum — from the Hebrides — Kári might be expected to conform to the established pattern. Instead, he emerges as one of the most loyal, capable, and morally grounded figures in the saga corpus.

This apparent contradiction is not accidental. Kári’s character reveals the conditions under which Hebridean identity could be rendered acceptable — or even exemplary — within the Icelandic narrative imagination. His legitimacy is grounded in genealogy and affiliation. Although associated with the Hebrides, he is not presented as culturally unstable in the way Kotkell or Hrapp are. His lineage connects him to Þorbjörn “Jarl’s Champion” and through that line to the Orcadian court — situating him within the prestigious lateral axis linking Iceland, Orkney, and Norway, rather than the more ambiguous vertical axis of the Hebrides and Ireland. His service to Sigurðr the Stout, Earl of Orkney, reinforces this positioning, and in narrative terms he embodies the virtues most valued in the saga world: loyalty, endurance, and controlled violence.

A similar, if less fully developed, pattern appears in the figure of Álfgeir in Eyrbyggja saga. Explicitly identified as a Hebridean, he arrives as captain of a ship jointly owned by Norwegians and men of the Hebrides. He is not a sorcerer or outsider but a leader among his men, integrated into the social world of his Icelandic hosts. When conflict arises at Mávahlíð, he functions not as a destabilising force but as an ally — good in a fight and sound in counsel. He is contrasted directly with his Scottish companion Nagli, described as well-built and a swift runner, but given to flight. A skaldic verse celebrating Álfgeir captures the contrast:

The grovelling Nagli, little gave he to glut hungry ravens as he ran snivelling up the ridge: as for helmed Alfgeir, eager for the war-play was the warrior, wielding his steel-bright weapons.

Compared to a Scot, Álfgeir is reliably Norse. Taken together, Kári and Álfgeir suggest that Hebridean identity in the sagas is not uniformly negative but conditionally acceptable. Both figures demonstrate that Hebrideans could be integrated into Icelandic society and their martial abilities valued rather than feared. They represent the possibility of controlled hybridity — a form of identity that can be accommodated, provided it is aligned with Norse authority, social order, and narrative purpose.

Conclusion

The Hebridean in the Icelandic sagas is a figure of considerable complexity and narrative significance. Positioned at the intersection of familiarity and difference, the Hebridean serves as a vehicle through which Icelandic authors explored the boundaries of identity, order, and cultural belonging.

Through recurring associations with Christianity in the earlier pagan period, and with magic, violence, and the supernatural in the later Christian period, the Hebridean becomes a narrative embodiment of instability — set in opposition to societal norms and expressive of anxieties surrounding hybridity and the limits of the Norse world. Figures such as Kotkell, Hrapp, and Þórgunna demonstrate how this instability could manifest across multiple domains: social, environmental, domestic, and ontological. Yet the inclusion of figures such as Kári Sölmundarson and Álfgeir complicates this picture. They could function as Norsemen — and impressive ones at that. The Hebridean is therefore not simply an “other” but a conditional other — a figure whose meaning depends upon context, alignment, and control.

The comparison with the Sami suggests a final way of understanding the particular force of the Hebridean stereotype. Both groups are situated at the margins of the Norse world and associated with specialised knowledge, especially in relation to magic and the manipulation of natural forces. Yet their narrative roles diverge in a significant respect. The Sami remain, for the most part, external to Icelandic society — figures encountered at a distance, whose difference can be observed, categorised, and at times incorporated without destabilising the social order. The Hebrideans, by contrast, belong to the same migratory world as the Icelanders themselves. They appear in settlement traditions, enter into kinship networks, and continue to move within the same maritime sphere. Their difference is therefore not distant but proximate.

It is this proximity that gives the Hebridean figure its particular narrative charge. Because Hebrideans could be neighbours, ancestors, and participants in Icelandic society, their hybridity — understood as a blending of Norse and Gaelic elements — becomes a source of tension rather than simple distinction. If the Sami represent the distant edge of the Norse world, the Hebrideans mark its unstable interior boundary, where identity is no longer secure and must be actively negotiated. The Hebridean is not merely an “other” but a near other — a figure whose closeness makes difference more difficult to contain.

Postscript

Finally, what are we to make of the fact that the stories associated with Hebrideans in saga material have parallels in Gaelic and Old Irish tradition?

There is the destructive gaze of Stígandi, which closely recalls Balor of the Evil Eye in the Cath Maige Tuired, whose sight brings devastation and death. There is the blood-rain episode associated with Þórgunna, which finds a clear analogue in Irish annalistic tradition, where phenomena such as “blood falling over Ireland” are recorded in the Annals of Ulster as ominous portents of death and upheaval. The case of Víga-Hrappr introduces a further parallel: his burial upright beneath the threshold, so that he may continue to “watch over” his household, resonates with the Irish tradition concerning Lóegaire mac Néill, said to have been interred standing, armed, and facing his enemies at Tara. Where Lóegaire’s burial is framed in heroic and royal terms, Hrapp’s is antisocial and destructive — yet the shared emphasis on upright interment is clearly a shared motif.

Then of course, there is the seal imagery. Seals occupy a more prominent position in Hebridean and West Highland Gaelic folklore than in Icelandic tradition, appearing in stories of human-seal hybridity and interbreeding. The Gaelic conception of seals as Clann Righ Lochlainn fo gheasaibh — the children of the King of Norway under enchantment — and the tradition that the MacCodrums of North Uist descended from a seal woman, both point to a rich imaginative framework centred on these liminal, hybrid beings. The Gaelic word for seal, ròn, is even embedded in Gaelic personal names: Mugrón, Abbot of Iona (d. 980 AD), and St Rónain, Abbot of Kingarth (d. 737 AD). For an audience in the Faroe Islands, the resonance of this tradition will need no underlining: the seal lore of the Faroese, with its own rich traditions of human-seal encounter and transformation, belongs to the same broad cultural complex.

Taken together, it seems to me that these parallels suggest that the saga authors were drawing on a Gaelic imaginative framework to highlight the hybridity of the Hebrideans — and that this framework was available to them because it had been transmitted, through the Hebridean community itself, into the cultural milieu of the Norse Atlantic world.

John Shaw (2002) in his study of Gaelic Norse folklore contacts came to a similar conclusion. He suggested “Gaelic” elements in Icelandic sagas likely arrived via Hebridean migrants. One of his examples is particularly intriguing, he noted the striking parallel between the story of Glámr in Grettis saga and Scottish Gaelic oral tradition. Glámr is not described as a Hebridean, but he is a draugr and terrorizes the hero Grettir by straddling his roof and kicking the house with his heels. A nearly identical motif exists in the Lochaber region of Scotland, where a man named Dòmhnall Bàn is haunted by a bòcan (ghost) that similarly rides the rooftop and kicks the walls. Shaw argues the words used are almost identical, and suggests that this motif is a surviving vestige of a formerly widespread body of shared tale elements.

I hope this has given you something to think about — and perhaps made you look at the seals out there in the harbour with slightly more suspicion than before.

Thank you very much for listening. I’m very happy to take any questions.

And I will leave the last word to Jarl Rögnvaldr of Orkney, who warned that “Not many Hebrideans are to be trusted...”

There are some archaeological sites that lodge in the imagination and refuse to leave. For me, the Kame of Isbister has been one of those sites for years. A 38-metre high rocky headland of mica slate jutting into Yell Sound from the remote parish of Northmavine in northern Shetland, it is becoming, through coastal erosion, an increasingly isolated sea-stack. Access is now only possible by a hairy roped ascent with pitons, or a dodgy small boat experience. Swimming is also an option! The nearest settlement is a kilometre’s walk over rough grazing land. And yet, on its summit and sloping flanks, there are the remains of some 23 rectangular stone-and-turf structures, a possible rampart, and deposits that have produced a suite of radiocarbon dates placing human activity here from the late 9th through to the early 12th century. The ambition to understand this site has been with me for years, and the 2024 season—carried out in collaboration with Professor Gordon Noble of the University of Aberdeen, who was hoping to add the Kame to his list of Pictish sites explored in his Northern Picts project —finally made it possible to put trowel to turf.

What follows is a summary of that work, its results, and what we think it might mean—while being honest about how much remains to be resolved.

The Site and Its Setting

The Kame of Isbister (HU 3816 9150; Scheduled Monument SM3880) sits in the parish of Northmavine, North Roe, some 40 miles north of Lerwick. It is a site of genuinely striking presence. From the sea, despite the structures standing only around half a metre above the turf, they are clearly visible from the coast of Yell, 5.5km across the Sound. That seaward perspective matters enormously for how we interpret the place. Standing on the Kame, one does not feel hidden; one feels dominant. The headland commands the view in every direction.

The enclosed area measures approximately 95 x 55 m. On the summit are around 15 rectangular structures, with three more on the south-eastern edge and one or two near the bottom of the slope adjacent to an earthen bank or possible rampart. The larger summit buildings measure roughly 7 x 3 m internally; the isolated building lower down is approximately 8 x 4 m internally. On its western side the Kame is connected to the Shetland mainland by a knife-edge ridge, now impassable. A deep sea-cave penetrates the northern face. On the eastern side, bare rock faces directly onto Yell Sound.

The structures are small and rectangular, similar but generally smaller than the Viking houses on Brough of Deerness, Orkney, though one Deerness structure, Structure 23, is of similar dimensions and construction. However, the structures also resemble those of Brei Holm, Shetland, from which 5^th to 7^th century dates have been recovered from associated pottery. Thus, a Pictish and/or Viking Age date seemed likely based on morphology alone and the radiocarbon date from the Extreme Archaeology series suggested that late Pictish/early Viking Age phases of activity are definitely present on the stack.

Previous Research: From Pechts’ Houses to Eremitic Monks

The site’s investigative history reflects the changing fashions of archaeological interpretation rather well. In 1876, George Cockburn—a divinity student from Aberdeen, visiting at the behest of the Reverend Dr G. Gordon—recorded 23 buildings, which the local population called ‘Pechts’ Houses’, Pecht is the Shetland dialect word for Pict, used loosely to mean any old building of obscure origin. Cockburn noted two rows of 17 buildings above the bank, most with their entrances facing south-east. The structures appeared to be partly excavated into the ground and partly built up, the builders clearly making use of the natural lie of the land. He trenched two houses and found ‘ashes and stones marked by fire, and what appeared to be the remains of a nail or some instrument of iron’ (Gordon 1878, 206). He also thought the plan resembled haaf-fishermen’s lodges—but concluded that no one would have chosen the Kame for that purpose, and that it had all the appearance of a site chosen for defence or refuge.

By 1970, Arthur Clarke of the Ordnance Survey could no longer reach the site—the access path had been lost to cliff falls—and surveyed it from the air. He identified only 19 buildings and suggested a ‘Celtic’ monastic origin, though he also drew a parallel with the Brough of Deerness. Raymond Lamb, working in the same decade, made the monastic interpretation the dominant one, identifying the Kame as one of a class of eremitic monasteries across Orkney and Shetland (Lamb 1973, 76-83; 1980). This view proved influential for decades (Turner 1998; Dumville 2002; Fojut 2006), creating what Jennings (2016, 52) has called an impression of the pre-Norse Northern Isles as a hive of Christian activity for which there is actually very little unequivocal evidence.

The first modern intervention came in 2003, when Channel 4’s Extreme Archaeology, led by archaeologist Katie Hirst, excavated roughly 8 square metres across six trenches—in 70 mph winds and driving rain. The team confirmed the turf-and-stone wall construction and recovered no artefacts, but a silty deposit in Trench 3, interpreted as an episode of burning, produced a radiocarbon date of WK-14016: 1139 ± 44 BP—770 to 990 cal AD at 95.4% probability.

From 2014 onwards, sustained effort to understand the site gathered pace. I used drone photogrammetry to produce a 3D model of the headland. In September 2014, I accessed the site by swimming from a boat and climbing the rocks with colleagues Dr Simon Clarke and Dr Marc Chivers—spending 15 minutes on site exploring the buildings and embankment. A return visit in August 2018 saw an hour spent measuring buildings and assessing whether safe roped access was feasible; it was. Sub-centimetre accurate drone models, created with GPS data in 2019, provided the detailed baseline for the excavation that followed in 2024.

A Scheduled Monument in Trouble

Before discussing what we found in the ground, it is worth being direct about the condition of the site, because it shapes everything about how we think the archaeology should be approached.

Cockburn recorded 23 buildings in 1876. Clarke could only identify 19 in 1970. The drone survey suggests similar numbers to Clarke’s count, meaning at least four buildings Cockburn saw have been lost to the sea. Comparing the 1970 OS plan with the current elevation model makes the scale of change stark: an area of the stack on the southernmost side has been lost entirely, and land east of the landward bank recorded in the 1970s has now gone.

The 2024 season made the situation still clearer. The access ridge had degraded substantially since 2003. Where Hirst’s team in 2003 had a level walk to the foot of the first ascent, we had to descend 2-3m before beginning to climb. Fresh erosion scars were prominent near the most difficult section. The seaward bank or rampart had been removed entirely at the location where we had proposed Trench 5. The landward rampart section is now perched on overhanging bedrock—it cannot always have been in that position—indicating active undercutting from below. Extensive burrowing is now present across the landward rampart. The northern stretches of the rampart have been lost entirely, and the exposed sections show little stone component, suggesting this may always have been primarily an earthen bank.

There is no question that access will continue to deteriorate, and that elements of the monument itself will continue to be lost. This makes further work urgent, while also making it progressively harder to carry out.

The 2024 Excavations

Scheduled monument consent was obtained to excavate a series of evaluation trenches targeting the buildings, the ramparts, and the spaces between structures. Access constraints significantly limited what was achievable: it took 45 minutes to an hour to get two archaeologists safely onto site on each occasion. Four trenches were opened; Trenches 3 and 5 were not attempted—Trench 3’s location was riddled with otter burrows, and the rampart at Trench 5’s proposed location had been removed by erosion.

Trench 1

Trench 1 (2 x 2 m) targeted one of the eroding structures at the southern end of the stack. Below topsoil (1001) and an overburden of shattered stone (1002, c.0.15m), a very thin deposit of yellow-brown clayey silt (1003) was identified that might represent an ephemeral floor surface. On reflection, this area appears on the 3D model to be an erosion hollow rather than a standing structure; any building that was here has most likely already fallen into the sea.

Trench 2

Trench 2 was the productive heart of the season. L-shaped in plan, it measured approximately 1.8 x 5.5 m across Building 1 and around 3 x 4 m across Building 2, with a passageway (context 2026) of approximately 0.8m between the two structures.

In Building 1, a shallow floor or foundation layer (2025) of mid-greyish brown clayey silt was entirely sterile—no charcoal, no organics—which is in itself telling. Around 40% of the deposit was sampled, the rest left in situ. At the top of the deposit, an iron angle-backed knife (Find 201) was recovered. This is a form well known in both Pictish and Viking secular contexts, a straightforwardly domestic object. The two walls of Building 1 (2020 and 2022) were each built of single-faced local stones revetting an earth or turf core, surviving to around 0.4m.

Building 2 offered a more complete sequence. The southern wall (2005) was the best-built element in the trench, surviving to 0.4m in three coursing levels, using local metamorphosed sandstones and mudstones. The northern wall (2003) survived to similar height with up to four courses. Both walls shared an important feature: the upslope c.1.4m of each had no formal stone facing at all, simply cut into the natural soils of the stack. This end of each building was probably a storage area: the basal deposit (2013) was almost entirely sterile, with only a rough paving surface (2012)—including a reused pivot stone—as evidence of any formal floor treatment.

The downslope end told a different story. A floor deposit (2015) of mid-reddish brown clayey silt with occasional charcoal and ash flecks represented a beaten-earth living surface. At its top was a line sinker stone—a perforated pebble used for dorro fishing, specifically for catching saithe in the medium-depth waters of Yell Sound (Chivers 2019). The hearth (2009) abutting the southern wall was compact—about 0.5 x 0.4 m 0.1m deep—filled with dark, charcoal-rich silt containing burnt small twigs and fragments of burnt bone. A bulk sample (S201) was taken from the hearth and a further sample (S202) from the floor deposit for radiocarbon dating and environmental analysis.

Overlying both buildings’ floors was a stone collapse layer (2010) up to 0.3m deep, with the bulk of material concentrated at the upslope end—consistent with natural deposits pushing out the upper wall courses over time. Above the collapse sat approximately 0.2m of shattered stone (2002) from further degraded wall material, then topsoil.

Trench 4

Trench 4 (m) targeted the isolated building on the east side of the site—the ‘boat-shaped structure’ of the Extreme Archaeology report. Our trench extended from the uphill western side into the interior.

A wall (4005) was identified on the western side, around 0.3m wide and 0.1m high, in two main courses of local stone. Below the stone collapse (4002) inside was a floor or foundation deposit (4003) of occasional flat slabs in a matrix of gravel and yellow-brown clayey silt. A small charcoal concentration (4004, c.0.02m thick) was identified on the floor surface towards the upslope side, and a bulk sample (S402) was collected for dating. Like the other buildings, the interior showed remarkably little accumulated deposit.

A New Chronology: Results of the 2024 Dating

The most significant result from the 2024 season is the arrival of four new radiocarbon dates. These provide a much firmer chronological anchor than the single date obtained in 2003, and the results are later than previously expected. Activity at the Kame is now looking squarely like a later 10th- through to early 12th-century phenomenon.

Statistical modeling of these dates, alongside the 2003 sample, suggests a 68% likely start date of 880–990 cal AD and an end date of 1030–1130 AD. This refined chronology places the site not at the beginning of the Viking transition, but firmly within the period of consolidation.

A crucial interpretive detail is that the charcoal from the 2024 season (Building 2 hearth, floor, and Building 4) comes primarily from heather. In the Shetland context, this likely represents the burning of peat. Because peat can be significantly older than its time of use, these dates must be used as a terminus post quem (TPQ) for the individual structures. This reinforces the likelihood that the site’s primary use was in the 11th century or even later, potentially connecting it to the consolidation of the Norse Earldom.

What Does It Mean? The Interpretive Debate

The Case Against a Monastery

The monastic interpretation has never rested on particularly solid ground, and the 2024 results do nothing to support it. Genuine early medieval monastic sites in Scotland and Ireland consistently produce specific markers: carved stone sculpture, cross-slabs, shrine fragments, chapels with characteristic orientations, clochan ‘beehive’ cells, leachta altar stones. The Kame has none of these—not in the 2024 trenches, not in Cockburn’s account, not in the Extreme Archaeology investigation. Monastic sites associated with the papar are typically found on good agricultural land (MacDonald 1977); the Kame is a barren eroding stack.

The new dates further weaken the monastic argument by placing activity in a period long after the peak of the eremitic movement in the north. Furthermore, place-name evidence is instructive. While the name derives from Scots kame (’steep-sided ridge’), likely from Old Norse kambr, while Isbister reflects ON bolstadr (’farm settlement’)—suggesting the original name of the settlement has been lost, significantly, other stack sites in Shetland discussed by Lamb do carry relevant terminology: Burri Stacks, Strandibrough, Sumburgh, and Burgar all derive from Old Norse borg, meaning ‘fort’ (Jennings 2020).

Stronghold, Assembly Site, or Both?

The question of exactly what kind of secular site the Kame represents remains genuinely open. One compelling possibility is that it functioned as an early Norse assembly or thing-site. The building forms are strikingly similar to the seasonal booths (Búðir) documented at the medieval assembly site of Skuldaþingsey in Iceland, where structures range from 5.8 x 4.3 m to 11 x 5.3 m (Vesteinsson et al. 2004)—closely bracketing the Kame’s dimensions. Icelandic assembly booths typically had permanent stone and turf walls but temporary roofs, which aligns with the quickly-built character of the walls and the shallow floor deposits found in 2024. The 11th-century dates now place the site in the heart of the period of increased political organization in the Earldom.

A stronghold interpretation is equally plausible. The Orkneyinga Saga‘s account of the 12th-century chieftain Sveinn Asleifarson and his vigi at Lambaborg in Caithness—a sea-cliff fortress from which he raided—is suggestive of exactly the kind of use the Kame’s topography would have supported. The Kame may have been a high-status center connected to the consolidation of the Earldom, commanding Yell Sound during a period of intense regional power struggles.

The artefacts from 2024 are modest but consistent. The iron angle-backed knife is a domestic tool. The line sinker points to active exploitation of the fisheries. The hearth in Building 2, domestic and compact, implies seasonal or intermittent habitation. The consistently thin, largely sterile floor deposits across all sampled structures is perhaps the most significant overall finding: this is not a site of intensive, long-term occupation. Whether that reflects seasonal assembly use or periodic raiding activity, we cannot yet say with confidence.

What Comes Next

The 2024 season has confirmed both that there is more to find and that the urgency of finding it is real. Further excavation is desirable and, given the erosion situation, increasingly urgent. The better-preserved buildings in the site’s interior should be the priority for future seasons. The rampart areas and erosion margins are now largely unsuitable: too disturbed by burrowing, too undercut, and too dangerous to work safely. There is still much the Kame can tell us about the Norse period in Shetland, but the window for gathering that evidence is narrowing with every storm.

I. Introduction

The genetic history of the Orkney Islands presents a compelling narrative of paradoxes. Situated at the “edge of the world,” the archipelago has been a nexus of both profound, multi-millennial genetic isolation and successive, large-scale migration events. Recent genomic studies utilizing both ancient and modern DNA have illuminated this complex past, revealing a population history defined by three primary demographic phases.

The first major transformation occurred during the transition from the Neolithic to the Bronze Age. This period was not a simple population replacement, as seen in much of Britain, but a unique, sex-biased event. While genome-wide and maternal (mtDNA) ancestries were substantially replaced by incoming continental populations, the indigenous Neolithic paternal (Y-DNA) lineages astonishingly persisted. This event established a small, new founder population that subsequently entered a long period of insularity.

This insularity became the dominant evolutionary force shaping the Orcadian gene pool for millennia. This is evidenced by a powerful and continuous signature of intense genetic drift, detected in ancient Orcadians from the Bronze Age, through the Iron Age, and persisting in the modern population. By the Iron Age, this long-term isolation had forged a distinct Orcadian Pictish population, genetically differentiated from its mainland contemporaries.

The final major layer was added during the Norse-Viking period. This was not a replacement but an extensive admixture event, as Scandinavian populations integrated with the established, drifted Iron Age population. The modern Orcadian genome is a direct product of this layered history—a palimpsest demonstrating clear genetic continuity with its bottlenecked, drifted Iron Age ancestors, which was then permanently overprinted by a major Norse genetic influx.

II. Methodological Foundations: Analyzing Ancient and Modern Orcadian DNA

The nuanced understanding of Orkney’s population history is built upon sophisticated analysis of genomic data from both ancient human remains and modern inhabitants. Two key studies provide the evidentiary basis for this report, each focusing on different temporal periods and employing complementary methodologies.

The first study, focusing on the Neolithic-Bronze Age transition, generated new genomic evidence by comparing genome-wide single–nucleotide polymorphism (SNP) capture and shotgun data from 21 Early Neolithic Orcadians with 22 Bronze Age and 3 Iron Age individuals from Orkney. This analysis was granular, specifically examining patrilineal (Y-chromosome, or Y-DNA) and matrilineal (mitochondrial, or mtDNA) haplogroups to trace distinct lines of descent. The study employed a suite of bioinformatic tools, including smartPC A and ADMIXTURE to investigate population relationships, qpAdm to quantify admixture proportions, and hapROH to assess runs of homozygosity, a key indicator of effective population size and endogamy.

The second study, focusing on the Iron Age through to the modern day, presented new high-quality genomes from two Pictish individuals (5th–7th century) from mainland Scotland, which were then co-analyzed with a massive dataset of over 8,300 previously published ancient and modern genomes, including ancient data from Orkney. This study utilized powerful haplotype-based approaches, including Identity-By-Descent (IBD) analysis, to measure the segments of DNA shared between ancient and modern individuals, thereby quantifying recent common ancestry. It also analyzed Homozygosity-By-Descent (HBD) segments in ancient individuals as a direct proxy for small population sizes and historical isolation. For a modern baseline, these analyses were compared against contemporary populations, including data from the Orkney Complex Disease Study (ORCADES).

III. The First Transformation: Neolithic Origins and the Bronze Age Paradox

The peopling of Orkney began with a foundational Neolithic population, which was then dramatically, yet complexly, transformed during the Bronze Age. This transition set the stage for Orkney’s unique genetic trajectory over the next four millennia. The distinct genetic signatures of each epoch are summarized in Table 1.

A. The Neolithic Baseline: Orkney’s First Farmers

Analysis of 21 Neolithic individuals from Orkney confirms their genetic roots trace back to Early European Farmers, who were ultimately derived from Anatolian Neolithic farmers. This population established a distinct patrilineal signature in the islands. Of the 16 known Y-chromosome haplotypes from this period, 14 were well-resolved and all belonged to Haplogroup I2a. This includes specific sub-clades such as I2a1b – M423. This Ia2 lineage, which was common among Neolithic farmer groups, represents the “indigenous” paternal line of Orkney prior to the Bronze Age.

B. The Bronze Age Influx: A Genome-Wide Replacement

The arrival of the Bronze Age, associated with the Bell Beaker Complex, triggered a massive demographic shift across Britain. Analysis of 22 Bronze Age Orcadians reveals that the islands were no exception to this broad-scale event. The data indicates a “substantial replacement” of the Neolithic population at the genome-wide (autosomal) level. This new population carried significant ancestry derived from the Pontic-Caspian Steppe, the genetic marker of this vast continental migration.

This genomic replacement is mirrored in the maternal lineages. The study of mitochondrial DNA (mtDNA), which is passed from mother to child, showed that the majority of mtDNA lineages found in Bronze Age Orcadians “evidently arrived afresh”. This provides clear evidence for a large-scale influx of immigrant women from the continent, who largely replaced the existing Neolithic female gene pool.

However, this maternal replacement was not absolute. The same study also found clear evidence for continuity in some female lines of descent tracing back to Mesolithic Britain, which persisted through the Bronze Age and “even to the present day”. This continuity is demonstrated by specific findings within the ancient samples. For example, while a Neolithic individual from Scotland carried the mtDNA haplogroup U5b2c, two Middle Bronze Age individuals from the Links of Noltland in Orkney were found to carry the related U5b2a3b haplogroup , showing a clear line of persistence for this maternal lineage alongside the new, incoming lineages.

C. The “Extraordinary Pattern”: Persistence of Neolithic Paternal Lineages

Despite the overwhelming evidence for a genome-wide and maternal-line replacement, the paternal lineages in Bronze Age Orkney reveal an “extraordinary pattern” of continuity. Genetic analysis of nine Bronze Age males from Orkney found that all but one belonged to the Y-DNA Haplogroup I2a1b – M423. This is the exact same lineage that dominated the local Neolithic population.

This finding is remarkable because this I2a haplogroup was “largely replaced” by the incoming haplogroup (associated with Bell Beaker expansion) in nearly every other part of Britain. In Orkney, only a single Bronze Age individual was found to carry the incoming R1b – M239 haplogroup. This demonstrates that the indigenous Neolithic male lines not only survived the massive genomic replacement but continued to thrive, persisting for “at least a thousand years” after the end of the Neolithic period.

D. A Sex-Biased Admixture as the Origin of Orcadian Insularity

This apparent paradox—a ~95% genome-wide replacement occurring simultaneously with a near-total persistence of local male lines—can be resolved by modelling a complex, sex-biased social process. The data strongly suggests “ongoing patrilocal marriage patterns,” in which the small, indigenous Neolithic male population (carrying I2a) preferentially married incoming women from the new continental-ancestry population.

This process would have rapidly transformed the autosomal and maternal gene pool while preserving the local Y-DNA. Such a high level of continental genome-wide ancestry (approximately 95%) could have been achieved in as few as five generations (100 to 150 years). Crucially, the genetic model that explains this pattern suggests that this rapid, sex-biased admixture was “followed by a period of isolation and endogamy”.

This hypothesis is independently and powerfully confirmed by the findings of the second study. Analysis of Bronze Age Orcadian genomes shows they were already “differentiated from their counterparts on mainland Britain”. The reason for this differentiation was “strong genetic drift” resulting from a “small ancestral population size”. This small population size is evidenced by a “relatively high number of short runs of homozygosity” (ROH) in their genomes.

These two lines of evidence are not separate; they are cause and effect. The “period of isolation and endogamy” proposed by the PNAS study is the “small ancestral population size” and “strong genetic drift” detected by the PMC study. Therefore, the unique, sex-biased admixture event that occurred in the Early Bronze Age created a profound population bottleneck. This bottleneck marks the originating event of the long-term genetic insularity that would become the defining characteristic of Orkney’s genetic history for the next 4,000 years.

IV. The Enduring Signature of Insularity: Genetic Drift Across Millennia

The population bottleneck created during the Bronze Age admixture event set Orkney on a distinct genetic path. The primary evolutionary force acting on the Orcadian gene pool from that moment until the Viking Age was not migration, but the profound effects of genetic drift within a small, isolated population.

A. A Multi-Millennial Signature of Isolation

The genetic isolation that characterizes modern Orcadians is not a recent phenomenon. The genomic data provides an unbroken, 4,000-year timeline of this insularity.

• Bronze Age: As established, the population was already genetically differentiated from the mainland due to “strong genetic drift” and a “small ancestral population size”.

• Iron Age / Viking Age: This isolation continued unabated. Analysis of three ancient Orcadians from the Late Iron Age and Viking Age (pre-admixture) revealed they possessed the “highest number of small Homozygosity-By-Descent (HBD) segments” (< 1.5 cM) among all ancient individuals in the study. This pattern is “typical of individuals descending from a small population”.

• Modern Age: This genetic signature persists directly to the present day. Modern Orcadians exhibit a “high proportion of shared IBD segments” (ranging from > 1 cM to > 6 cM) relative to other modern European populations. This demonstrates that they share a high proportion of recent common ancestors, a feature “typical of small or genetically isolated populations”.

This continuous line of evidence confirms that insularity is the fundamental baseline upon which all later genetic events, including the Norse admixture, must be interpreted.

B. Quantifying Ancient Insularity: HBD and Consanguinity

The analysis of HBD segments provides a direct, quantifiable measure of this long-term small population size. The genomes of the Late Iron Age and Viking Age Orcadians clearly show the cumulative effects of endogamy. The case of one ancient individual from Orkney, designated VK201, is particularly illustrative. This individual possessed an HBD segment “over 9.5 cM,” which was the longest such segment observed among all ancient individuals sampled in the study. A segment of this length is a clear genomic signal of either a chronically small population size or recent parental consanguinity, providing a stark, individual-level example of the population-wide trend.

C. Visualizing Drift: The “Red Ancestry Component”

The profound effect of this 3,000-year period of drift is visually captured in population relationship analyses. An ADMIXTURE plot—a tool that models an individual’s genome as a mixture of different ancestral populations—identified a “red ancestry component”. This component was found at its highest degree in the Iron Age and unadmixed Viking Age Orcadians.

This “red component” should not be misinterpreted as a unique “Pictish” ancestry. Rather, it is the visible, statistical artifact of the 3,000-year-old genetic drift. The study authors hypothesize that this component reflects the “retention of a less diverse pre-Iron Age ancestry” and/or “strong genetic drift”. Connecting this to the Bronze Age transition, this “pre-Iron Age ancestry” is, in fact, the Bronze Age founder population. The “red component” is what happens to that founder population’s genome when it is isolated for millennia. Its allele frequencies drift so significantly from its parent population that the ADMIXTURE algorithm identifies it as a new, distinct ancestral group. This component is, in effect, a “ghost” of the Bronze Age bottleneck, amplified by 3,000 years of isolation.

V. The Iron Age and the Viking Admixture: Forging the Modern Orcadian

The genetic baseline established by the Bronze Age bottleneck and subsequent Iron Age drift was the population that encountered the next major demographic wave: the arrival of the Norse. This final phase completes the story of how the modern Orcadian population was forged.

A. The Genetic Profile of the Orcadian Picts

The population of Orkney during the Iron Age (contemporaneous with the Pictish period) was the direct descendant of the Bronze Age founder group. As a result of the long-term genetic drift detailed in Section IV, the PMC study demonstrates the presence of clear “population structure within Pictish groups”. Specifically, the “Orcadian Picts” were found to be “genetically distinct from their mainland contemporaries”.

This distinction is not evidence of a separate origin. As the study itself explains, this differentiation “could thus be partially explained by different degrees of genetic drift”. The Orcadian Picts were genetically different from mainland Picts precisely because their ancestors had been living in a small, insular gene pool since the Bronze Age. It was this highly drifted, genetically distinct population that provided the “substantial genetic continuity” linking ancient Orkney to the modern day.

B. The Fading of a Lineage: The Disappearance of Neolithic Y-DNA

This period also resolves the story of the anomalous Neolithic paternal line, Haplogroup I2a . While this lineage heroically persisted through the Bronze Age replacement event, the PNAS study notes that this unique signal of continuity “had dwindled by the Iron Age”. This indicates that the R1b haplogroups (such as R1b – M269), which had come to dominate mainland Britain during the Bronze Age, eventually did replace the I2a lineage in Orkney as well. This replacement, however, appears to have been a slow, gradual process of gene flow during the Iron Age, rather than the dramatic, sex-biased event of the Early Bronze Age.

C. The Second Great Transformation: The Norse-Viking Admixture

The arrival of Scandinavians in the Viking Age marks the second major migration event to fundamentally shape Orkney. The genetic data confirms this was a massive demographic event. Modern Orcadians are “differentiated from the rest of the British Isles” due in large part to “extensive admixture with Scandinavians”.

It is critical to differentiate this event from the Bronze Age transformation. The Bronze Age event was a replacement of ~95% of the genome, which created a new founder population. The Viking Age event was an admixture event, where a large new Scandinavian population mixed with the established, local, and highly-drifted Iron Age (Pictish) population.

VI. Synthesis: The Modern Orcadian Genetic Profile

The contemporary Orcadian genome is a multi-layered palimpsest, a direct record of the complex demographic history of replacement, isolation, and admixture that has unfolded on the islands over 5,000 years.

A. A Dual Legacy: Ancient Drift and Viking Admixture

The modern Orcadian genome is primarily the product of two powerful forces acting upon the Iron Age (Pictish) population baseline.

1. Force 1: Continuity and Genetic Drift. Modern Orcadians are the direct descendants of the Iron Age inhabitants of the islands. This is confirmed by analyses showing “substantial genetic continuity in Orkney for the last ~2,000 years”. The genetic signature of this long-term continuity is the drift that accumulated over millennia. This “genetic structure in Scotland during the Iron Age” (the highly drifted component) is “also detected in present-day Orcadians”. The high proportion of shared IBD segments in the modern population is the living legacy of this descent from a small, isolated ancestral pool.

2. Force 2: Admixture. This baseline of deep, drifted ancestry is overlaid by the second dominant force: the “extensive admixture with Scandinavians” during the Viking Age. This event contributed a massive new component to the Orcadian gene pool, differentiating Orcadians from populations in the rest of the British Isles.

B. Concluding Analysis

In conclusion, the genetic history of modern Orcadians can be understood as a three-layered process:

1. The Substrate (Neolithic): An initial population of Early European Farmers whose genome was almost completely erased autosomally. They left behind a fascinating “ghost” lineage—the paternal Haplogroup I2a —that uniquely defined the subsequent Bronze Age population.

2. The Foundation (Bronze/Iron Age): The true genetic foundation of modern Orcadians. This population was established in the Early Bronze Age from a ~95% Steppe-ancestry migration. However, this founding population was small and immediately entered a period of isolation, which led to 3,000 years of “extensive” and “strong” genetic drift. This isolation moulded this population, creating the genetically distinct Orcadian Picts.

3. The Overprint (Viking/Modern): This “substantial genetic continuity” from the Iron Age Picts was then met by a final, massive wave of “extensive admixture with Scandinavians”.

Genetically, Orkney represents a perfect natural laboratory. It demonstrates, in successive order, the profound impacts of population replacement (Bronze Age), the powerful and enduring effects of long-term isolation (drift), and, finally, the transformative signature of large-scale admixture (Viking Age).

Welcome to my new Substack exploring the Vikings in the North Atlantic Islands! You can receive the occasional free post if you want, or if you feel like subscribing, I’ll be adding longer, more detailed posts for members.

For my first post, I wanted to start with a place that isn't just a historical curiosity, but a part of my daily landscape. I’m incredibly lucky to live just a ten-minute drive from Jarlshof, one of the most remarkable archaeological sites in Europe, and it feels only right to begin our journey here.

To stand at Jarlshof is to stand in several worlds at once. Perched on the southern tip of Shetland's mainland, battered by the North Sea wind, this single headland holds over 4,000 years of human history. It's a place where you can literally walk from a Bronze Age smithy to an Iron Age broch, past Pictish wheelhouses, and straight into the heart of a Viking settlement.

What makes Jarlshof so special is not just the sheer span of time it represents, but the intimate glimpse it offers into the lives of the people who called this place home. The acidic soil of Shetland means that organic materials rarely survive, so the stories are told through stone, bone, and the faint traces of everyday life.

The excavations at Jarlshof have unearthed a treasure trove of artifacts that paint a vivid picture of the past. In the Bronze Age settlement, archaeologists found not only the remains of oval houses with thick stone walls but also a smithy, with broken molds for axes, knives, and swords, evidence of a skilled craftsman trained in what seems to be the Irish style. An extraordinary decorated bone plaque, its purpose still a mystery, was also discovered here.

The Iron Age is represented by the imposing remains of a broch, a defensive stone tower, and a complex of wheelhouses. It is in the later Pictish period that we find some of the most intriguing finds, including a painted pebble and a fragmented incised slab bearing a serpent, offering a tantalizing glimpse into their artistic and symbolic world. (See https://doi.org/10.9750/PSAS.148.1273)

But for me, it's the Viking settlement that truly captures the imagination. Jarlshof is the largest visible Viking site in Britain, with the remains of a longhouse that was home to generations of Norse settlers. Excavations have revealed a wealth of everyday objects: bone pins and awls, loom weights and spindle whorls, and even a slate with a incised Viking ship and another with a beautifully sketched dragon's head. (See https://www.nms.ac.uk/search-our-collections/collection-search-results?entry=161746) Both Picts and Vikings liked serpentine monsters! They had that in common! These are not the treasures of kings, but the humble possessions of a farming and fishing community, a tangible link to their daily lives.

The story of Jarlshof doesn't end with the Vikings. A medieval farmstead and a 16th-century laird's house, the "Jarlshof" of Sir Walter Scott's novel "The Pirate," complete this incredible historical timeline.

Living so close to Jarlshof is a constant reminder that the past is never truly gone. It's a place that invites you to wander, to imagine, and to connect with the thousands of years of human history that have unfolded on this dramatic and beautiful corner of Shetland.

I hope you'll join me as I explore more of the stories that these islands have to tell. Subscribe to stay updated on our journey through the Viking islands. I’ll post a more detailed account of Jarlshof for subscribers.
