About Olvir Rosta

Olvir Rosta was a mercenary, known for Orkneyinga saga.

Olvir Rosta (Old Norse: Ölvir Rósta, and Ölvir Þorljótsson), also known as Aulver Rosta, is a character within the mediaeval Orkneyinga saga, who is purported to have lived during the early 12th century. His Old Norse byname, rósta, means "brawl", "riot". His name, and byname, appear variously in English secondary sources.

Ölvir appears in the saga as the son of Þorljót, and Steinnvör 'the Stout'. The mother of Steinnvör is Frakökk, who has been described as one of the great villains of the entire saga. One of Frakökk's sisters, Helga, is the concubine of Earl Hákon Pálsson. Part of the saga relates of how the Earldom of Orkney is for a time jointly run by half-brothers—Haraldr Hákonsson and Páll Hákonsson, who are both sons of Earl Hákon. With the death of Earl Haraldr, son of Helga, Frakökk's family falls out of favour, and are forced to leave Orkney. In time, Frakökk conspire with the father of Earl Rögnvaldr, and agrees to a plan to take the Orkney by force and split it with Earl Rögnvaldr. She and Ölvir eventually make their way to the Suðreyjar, and may their return in a bid to win half of the earldom. However, their small fleet of ships are defeated in battle against Earl Páll. The saga also tells of how Ölvir kills an Orkney chieftain who fought against him during the sea-battle—by burning the man to death within his house. The chieftain's vengeful son later tracks down Ölvir and Frakökk, at their own home in Sutherland. After a short battle behind their homestead, Ölvir's men are routed and Frakökk is burned to death within her house; Ölvir flees from the scene, making for the Suðreyjar, and is not heard from again.

Ölvir has also been associated with several places in Sutherland, some of which may bear his name. It has been proposed that Ölvir Rosta may be an ancestor of either one of two Scottish clans from the Outer Hebridean Isle of Lewis. In 1962 a runestone was uncovered in the Inner Hebrides which bore the name Ölvir. It has been suggested that the men mentioned on this stone were family relations of Ölvir.

Background

Ölvir Rósta, is a character in the mediaeval Orkneyinga saga. His name in Old Norse is Ölvir rósta. The 17th-century Icelandic historian Þormóður Torfason, who wrote Latin histories which covered events the Northern Isles and north-east of Scotland, rendered Ölvir's name as Aulver Rosta. Ölvir's byname, rósta, means "brawl", "riot". Both his name and byname are represented various ways in English secondary sources.

Locations associated with Ölvir, Frakökk, and Sveinn

Several writers have noted a place which is said to be the location of the burning. The Historic Environment Scotland website states that a supposed castle in which Frakökk was burned may be located at , near Kinbrace, within the parish of Kildonan. In 1769, Thomas Pennant noted the episode of the burning, and stated that certain ruins at Kinbrace were called "Cairn Shuin"; and that these were the remnants of the homestead that Sveinn burnt. Rev. Sage, in his account of the parish in the (Old) Statistical Account of Scotland, noted the ruins mentioned by Pennant; he called them "Cairn-Suin", and translated this to "Old Cairns". Sage, however noted Þormóður Torfason's account of the burning, and suggested that a possibly more accurate etymology is "Suenes Field". Pennant stated that "though the ruins are great, yet no man can tell of what kind they were; that is, whether round like Pictish houses, or not". According to the Historic Environment Scotland website, Pennant may have been referring to any of the chambered cairns in the area.

Speculation of Scottish descendants

According to Williams, it is possible that after Sveinn defeated Ölvir and Frakökk, Ölvir may have fled to kinsmen of his in the Suðreyjar. Williams suggested that the blood feud between the families may be a reason for Sveinn's military activities in the Hebrides and the Isle of Mann, afterwards; although Sveinn had other interests in the area, since he is stated to have married the window of a Manx king. In the late 19th century, antiquary F.W.L. Thomas speculated that the memory of Ölvir may have been preserved in the Hebrides. Thomas stated that within the mythological history of the Outer Hebridean Isle of Lewis, the island clan of Macaulays were said to be the descendants of a man named Amhlaebh, who was one of the twelve sons, or near relations, of a man named Oliver, among whom Lewis was divided. This Oliver was said to have been the eldest son of the Norse king who was given the Isles and Highlands by a son of Kenneth MacAlpin, for his assistance in driving his own brother from Scotland. Thomas speculated that Oliver could represent Ölvir Rósta; meaning that he was the progenitor of the Macaulays.

Several Gaelic language pedigrees of the MacLeods contain names which may be forms of the Old Norse Ölvir.

It has also been suggested that Ölvir may be an ancestor of the MacLeods. Until quite recently, it was commonly believed by historians that the eponymous ancestor of the MacLeods, Leod, was the son of Olaf the Black, King of Mann and the Isles. In the late 20th century, William Matheson proposed that the MacLeods descended in the male line from Ölvir Rósta, rather than Olaf the Black. Matheson proposed that, within several Gaelic pedigrees which record ancestors of Leod, the great-grandfather of Leod has Gaelic names which very likely represent the Old Norse name Ölvir. These Gaelic names are considered to equate to other Gaelic names found within the early bardic poetry of the MacLeods. About a century before, Thomas had noted the similarity in these names, when discussing Ölvir, but he did not pursue a specific link between Ölvir and the MacLeods. Matheson's association of Ölvir to the Macleods was also attacked by clan historian Alick Morrison. Morrison commented that the name Ljotr was also not as rare as Matheson had proposed. Morrison noted that, in the previous century, Thomas had considered another saga character to be an eponymous ancestor of the MacLeods—this character was Ljótólfr (mentioned earlier in the article), who would have lived on Lewis about a century before Leod's time. In fact, Morrison did not consider Ölvir's name—and the singled-out Gaelic names—to be anything but other forms of Óláfr. —may be a nominative form of the genitive snaithe, and thus may equate to Ölvir's byname. The fragment is about half the size of the original stone, the runes are located on the side, along the border. At the end of the inscription there are a few runes missing, due to the corner having been broken off. The runic inscriptions, and artwork, suggests that the stone dates to the late 10th century, or 11th century.

Liestøl suggested that the three men were somehow related to Ölvir. Liestøl noted that three names were those of characters in the Orkneyinga saga, which all had connections with the Hebrides. Kali was the original name of Earl Rögnvaldr, whom Ölvir fought for. The earl was named after his grandfather, Kali Sæbjörnarson, who according to the saga, accompanied Magnús 'Barefoot' to the Hebrides, and died there of wounds he received on Anglesey. Concerning the name Ljótólfr, Liestøl also noted that the saga names Ölvir's father Þorljót, and his maternal-grandfather Ljótr. He concluded that the men mentioned on the stone likely lived around the year 1000, about four to six generations before their namesakes in the saga. In consequence, Liestøl suggested that Kali Sæbjörnarson would have been a contemporary of the children of the rune-stone's Kali Ölvisson.
