Harald Gillichrist, illegitimate son of King Magnus Barelegs, was of Celtic extraction, his mother being a native of the Hebrides. He and his mother were brought over to Norway from the Southern Hebrides in a ship belonging to a Norwegian merchant named Halkel Húk. When the story of Harald’s parentage was told to King Sigurd, he consented to allow Harald to prove his paternity by the ordeal of hot iron, but on condition, that if he succeeded in proving his descent according to his claim, he should not desire the kingdom in the lifetime either of King Sigurd or of his son, King Magnus, and to this Harald bound himself by oath. This seems to be the oath referred to as given under compulsion. “The ordeal,” it is added in the Saga of King Sigurd, “was the greatest ever made in Norway, for nine glowing ploughshares were laid down, and Harald walked over them with bare feet, attended by two bishops, and invoking the holy St. Columba”—another testimony to his Celtic birth. His feet were then bound up, and he was laid in bed. After the customary three days had elapsed, his feet were examined, or, as the Saga has it, “the ordeal was taken to proof, and his feet were found unburnt.” His claims were therefore held to have been proven, and made good. It is curious to find that among the privileges granted by the Scottish King David to the monks of Holyrood, they were specially empowered to make trials by the ordeal of hot iron.

Footnote 322: Vík meant properly the bay of Oslo, the upper part of which is now called the Christiania Fiord, but it was also applied to the district bordering on the bay. Footnote 323: Harald and Eric, Kings of Denmark, had sworn mutual brotherhood. Footnote 324: Alasund is now Yell Sound, the ancient name for the island of Yell being Jala. In the latest known Hjaltland document, written in Norse, and dated in 1586, the name of the island appears as “Yella.” Footnote 325: Outsittings, a peculiar kind of sorcery resorted to in order to obtain foreknowledge of the future, in which the person sat out at night under the open sky, and by certain magical rites or incantations summoned the dead from their graves to consult them. A curious instance is given in the 40th chapter of the Færeyinga Saga, in which Sigmund Brestisson is brought from the dead, with his head in his hand, to show who was his murderer.
