Gilli
Hebridean earl
About Gilli
Gilli was an eleventh-century Hebridean chieftain whose career coincided with an era of Orcadian overlordship in the Kingdom of the Isles. According to mediaeval saga-tradition, Gilli was a brother-in-law of Sigurðr Hlǫðvisson, Earl of Orkney, having married the latter's sister Hvarflǫð. Traditionally regarded as one of the most powerful Orcadian earls, Sigurðr appears to have extended his authority into the Isles in the late tenth century. Gilli apparently acted as Sigurðr's viceroy or tributary earl in the region. The time frame of Gilli's apparent authority in the Isles is uncertain, and may date as early as the reign of GuðrÞðr Haraldsson, King of the Isles, or as late as the period following the death of this man's eventual successor, RÇ«gnvaldr GuðrÞðarson, King of the Isles. Gilli's name is probably Gaelic in origin, and he seems to have seated himself on either Coll or Colonsay, islands in the Inner Hebrides. It is possible that Gilli is identical to Gilla CiarĂĄin mac GlĂșn Iairn, an UĂ Ămair dynast who was slain at the Battle of Clontarf in 1014. If not, another possibility is that he was the father of a certain Conamal/ConmĂĄel who was killed in 980.
Earl in the Hebrides
There is evidence to suggest that Sigurðr Hlǫðvisson, Earl of Orkney extended his authority from Orkney into the Isles in the late tenth- and early eleventh century. For instance, the thirteenth-century NjĂĄls sagaâthe only source that specifically refers to Gilli âstates that one of Sigurðr's followers, KĂĄri SÇ«lmundarson, extracted taxes from the northern Hebrides, then controlled by Gilli himself. Whether these taxes were due to Norwegian overlords of Sigurðr, as the saga states, is uncertain. The saga further declares that Sigurðr and his men defeated GuðrÞðr Haraldsson, King of the Isles, after which they plundered the Isles. Also noted are additional assaults conducted by accomplices of Sigurðr throughout the Hebrides, Kintyre, Mann (against GuðrÞðr), and Anglesey. The thirteenth-century Orkneyinga saga also reports Sigurðr's raids into the Isles, as does Eyrbyggja saga, a thirteenth-century source which further notes his taxation of the kingdom. Contemporary Orcadian expansion may be perceptible in the evidence of the land-assessment system of ouncelands in the Hebrides and along the western coast of Scotland. If Sigurðr's authority indeed stretched over the Isles in the last decades of the tenth century, such an intrusion could account for the numbers of silver hoards dating to this time.
The name of GuðrÞðr Haraldsson as it appears on folio 15r of Oxford Bodleian Library Rawlinson B 488 (the Annals of Tigernach): "".
Various Irish annals also reveal that this was a period of strife in the Isles, as (literally "Danes") are recorded active in the region throughout 986 and 987. Although it is not impossible that the (perhaps merely meaning "pirates") refer to Sigurðr's forces, it is more likely that they are instead identical to the Vikings who are otherwise attested attacking England in the 990s. In fact, it seems that the were active in the region against opponents of GuðrÞðr. This could indicate that either the kin of the recently deceased AmlaĂb CuarĂĄn, King of Northumbria and Dublin, or perhaps an Orcadian-aligned Islesman like Gilli himself, may have fallen target to an alliance between the and GuðrÞðr. This could in turn reveal that the aforesaid claims of continuous Orcadian conquests in the Islesâotherwise unrecorded outwith saga-traditionâgive a less than unbiased account of events. Whatever the case, GuðrÞðr was slain in 989, after which the political cohesion of Kingdom of the Isles âperhaps shaken by Orcadian encroachment in the 980s âseems to have diminished. a population of mixed Scandinavian and Gaelic ethnicity located in the Hebrides and parts of the former kingdom of DĂĄl Riata. |group=note
Rocky moorland near Gallanach, Coll. A rocky hillside near Gallanach, known as Cnoc Ghillebhreide , has been associated with fairies, Colum Cille, and Gilli himself, since the early twentieth century. In 1972, the site was visited by the Ordnance Survey, with no evidence of antiquity being observed.
The extent of GuðrÞðr's authority in the Hebrides is unknown due to his apparent coexistence with Gilli, and to the uncertainty of Orcadian encroachment. GuðrÞðr's successor is likewise uncertain. On one hand, he may have been succeeded by his son, Rǫgnvaldr. Although it is conceivable that either Gilli or Sigurðr capitalised on GuðrÞðr's death, and extended their overlordship as far south as Mann, possible after-effects such as these are uncorroborated. Nothing else is certain of Rǫgnvaldr. |group=note Although it is possible that Gilli controlled the Hebrides whilst GuðrÞðr ruled Mann, the title accorded to the latter on his death could indicate otherwise. If so, the chronology of Gilli's subordination to Sigurðr may actually date to the period after Rǫgnvaldr's death in 1004/1005.
According to NjĂĄls saga, Gilli was seated on or , an island that appears to refer to Coll or perhaps Colonsay. The saga also states that Gilli was married to Sigurðr's sister, Hvarflǫð. This marital alliance appears to further evince the southward extension of Sigurðr's influence. This union, along with the record of apparent amiable dealings with Sigurðr's associates, suggests that Gilli and Sigurðr indeed enjoyed close relations. The earl's family was clearly not averse to marrying into native dynasties, as Sigurðr's own mother was the daughter of an Irish king, whilst his wife was the daughter of a Scottish king. In fact, the aforesaid sources appear to indicate that Gilli operated in the Hebrides as a tributary earl to his brother-in-law. Certainly, Eyrbyggja saga states that Sigurðr left menn ("agents") in the Hebrides to collect tax from Mann, whilst Orkneyinga saga reveals that, at a later period in time, Sigurðr's son and successor, ĂĂłrfinnr Sigurðarson, Earl of Orkney, tasked a member of his own wife's family, KĂĄlfr Ărnason, to impose Orcadian authority in the Isles.
Clontarf, Gilla CiarĂĄin, and Conamal/ConmĂĄel
The name of Sitriuc mac AmlaĂb as it appears on folio 16v of Oxford Bodleian Library Rawlinson B 488: "".
By the end of the first decade of the eleventh century, the principal ruler in Ireland was Brian BĂłruma mac CennĂ©tig, High King of Ireland. Brian's daughter, SlĂĄine, was married to Sitriuc mac AmlaĂb, King of Dublin, whilst the latter's mother, Gormlaith ingen Murchada was a former wife of Brian. In 1013, Sitriuc allied himself to Brian's enemies, and revolted against Brian's overlordship. Although Brian proceeded to lay siege to Dublinâthe only Viking town that participated in the revolt against his supremacyâSitriuc retained possession of the settlement, and Brian retired to Munster for Christmas.
The name of Sigurðr Hlǫðvisson as it appears on folio 36v of Oxford Bodleian Library Rawlinson B 489 (the Annals of Ulster).
According to NjĂĄls saga, Gilli and Sitriuc spent Yule with Sigurðr in Orkney, where Sitriuc convinced Sigurðr to ally himself against Brian on the condition that Sigurðr would gain Gormlaith in marriage. In April 1014, the opposing forces met and clashed at the remarkably bloody Battle of Clontarf. Although Brian's forces ultimately won the day, and Sigurðr himself was amongst the slain, Brian lost his life as well. As for Gilli, he appears in a chapter of NjĂĄls saga that presents a series of supernatural events connected with the conflict. In one instance, a Caithnessman is said to have witnessed valkyrie-like apparitions singing songs for the slain, whilst a similar event is said to have occurred in the Faroe Islands. Priests in Iceland are stated to have encountered paranormal phenomena, whilst an Orcadian is said to have encountered the spectre of Sigurðr before disappearing off the face of the earth. Regarding Gilli, the saga asserts that he dreamt of a song that foretold the outcome of the battle and the fall of Brian and Sigurðr. There is reason to suspect that the aforesaid supernatural manifestationsâarguably somewhat detached from the saga's general narrativeâare actually interpolations of separate material. Elsewhere in the narrative, however, there are examples of paranormal phenomena intervening into human affairs. For example, the episode concerning Gilli's dream seems to directly parallel an earlier episode in which another man, the Icelander Flosi ĂĂłrðarson, is depicted dreaming of the burning of the saga's eponym, NjĂĄll Ăorgeirsson.
The name of Hvarflǫð as it appears on folio 59r of AM 132 fol (Möðruvallabók).
Gilla CiarĂĄin's father bore a Gaelic name meaning "iron knee". It may or may not be a Gaelicisation of , an identical-meaning Old Norse name. Gilla CiarĂĄin's own name is Gaelic, meaning "the servant of Saint CiarĂĄn". Gaelic names beginning with the initial name-element - first appear on record in last half of the tenth century. Such names were shortened to by Scandinavian settlers in Britain and Ireland. In fact, such a phenomenon may account for the name accorded to Gilli himself. Gilli's name suggests that he was at least partly of Gaelic descent, perhaps either Irish or Hebridean. This name appears to be an Old Norse form of , a relatively rare Gaelic name.
The name of a certain Conamal as it appears on folio 33v of Oxford Bodleian Library Rawlinson B 489. The man's patronym in this source seems to refer to a royal title, whilst other sources seem to refer to a similar-looking personal name.
There may be further evidence concerning familial relations. In 980, MĂĄel Sechnaill mac Domnaill, High King of Ireland utterly defeated AmlaĂb CuarĂĄn's forces at the Battle of Tara. One of the casualties of this remarkable conflict was a man identified as "" by the Annals of Ulster, and "" by the Annals of Tigernach. It is possible that these annal-entries refer to a man named Conamal or ConmĂĄel, who was in turn the son of a man named Gilli, and that either the father or the son bore the title airrĂ Gall ("royal deputy of the Foreigners"). If correct, it is conceivable that this father is identical to Gilli himself. Against this identification, however, is the fact that the aforesaid saga-tradition depicts Gilli active at about the time of the Battle of Clontarf. The considerable span of time between the death of Conamal/ConmĂĄel and this conflict may well be evidence that a paternal relationship between Conamal/ConmĂĄel and Gilli is unlikely. Whatever the case, the sources appear to be confused as to whether the patronym refers to a personal name or a title. One possibility is that this confusion could indicate that the sources refer to both the personal name and the epithet .
