Thorfinn Hausacliuf died _c._ 963; and the rule of his five sons, Havard, Hlodver, Ljot, Skuli, and Arnfinn is noticeable for the first of those family feuds which form so marked a feature of the history of the Jarls. Skuli took the title of Earl of Caithness from the King of Scots, and fared against Ljot with a host provided by the King and the Scots Earl Macbeth. Ljot defeated him in the Dales of Caithness, Skuli being slain. Earl Macbeth with a second host, was in turn defeated by Ljot at Skidmoor (Skitton) in Caithness, and here Ljot fell. His other brothers having already disappeared in domestic strife, Hlodver was now left sole. He married Edna, an Irish princess, and their only son Sigurd Hlodverson, the Stout, is one of the most famous characters of the _Saga_. Succeeding his father in 980, Sigurd held Caithness by main force against the Scots. A Scots maormor, Finnleik, the father of the celebrated Macbeth, having challenged him to a pitched battle at Skidmoor by a fixed day, Sigurd took counsel of his mother, for she, as the _Saga_ says, “knew many things,” that is, by witchcraft. Edna made her son a banner “woven with mighty spells,” which would bring victory to those before whom it was borne, but death to the bearer. Armed with this uncanny device, Sigurd defeated his challenger at Skidmoor, with the loss of three standard-bearers. An incident of wider consequence, however, befell Sigurd in the year 995. Olaf Tryggvi’s son, King of Norway, came on the Jarl aboard ship in a small bay in the South Isles. The King had the superior force, and, a recent convert himself, he there and then forced christianity upon the reluctant Jarl, and laid him under an obligation to impose the faith upon the people of Orkney. The _Saga_ adds, “then all the Orkneys became christian,” and so indeed the Islands henceforth remained. Sigurd himself, however, reverted to the old gods, and in the year 1014, he joined the great Norse expedition against Brian, King of Ireland, which led to the battle of Clontarf. In that famous fight the Skidmoor banner again did service, but the spell was broken. “Hrafn the Red,” called out the Jarl after two standard-bearers had fallen, and an Icelander who knew its fatal secret had declined to touch it, “bear thou the banner.” “Bear thine own devil thyself,” rejoined Hrafn. Then the Earl said, “’Tis fittest that the beggar should bear the bag,” at the same time taking the banner from the staff and placing it under his cloak. A little after, the Earl was pierced through with a spear.
