The Earls Rögnvald and Harald visited King Ingi by invitation at Bergen, and there Earl Rögnvald met with Eindridi Ungi, a returned Crusader, and became possessed by a strong desire to visit the Holy Land. On his return voyage to Orkney, Earl Rögnvald was shipwrecked at Gulberwick in Shetland, and narrowly escaped with his life. Bishop William strongly approved of his project to go on a pilgrimage to the Holy Land, and agreed to accompany him. Accordingly he went back to Norway to organise the expedition, and returned to the Orkneys followed by a large number of Jorsala-farers—mostly adventurers of very indifferent character, if we are to judge by their turbulent and lawless behaviour during their stay in the Orkneys, where they spent the winter previous to their departure for the East. Early in the spring of the year 1152 Earl Rögnvald called a Thing-meeting of the inhabitants of the Islands, and told them of his purposed voyage, announcing that he was to leave the sole government in the hands of Harald during his absence, and asking them all to obey him and help him faithfully as their lawful lord. The summer was far advanced before he sailed, but he had a prosperous voyage, the adventures of which are detailed in the Saga; and after visiting Jerusalem and bathing in the Jordan, he returned by way of Constantinople, Durazzo, Apulia, and Rome, and so overland to Norway, the whole expedition occupying about three years. In the same summer that Earl Rögnvald left the Orkneys on his pilgrimage, King Eystein came from Norway with a large force, and seizing Earl Harald Maddadson as he lay at Thurso with a single ship, made him pay a ransom of three marks of gold, and swear fealty to him for Orkney and Shetland. Earl Maddad of Athole was now dead, and Margaret, the mother of Earl Harald, had come to the Orkneys. Erlend, the son of the Earl Harald (Slettmali), who was killed by the poisoned shirt, had set up his claim to half the earldom after Rögnvald’s departure. His cause was favoured by King Eystein, and espoused by Swein Asleifson, and Earl Harald was obliged to make peace by taking oath to allow Erlend to remain in possession of the Islands, an arrangement which was afterwards confirmed by a Thing-meeting of the Bœndr of the Orkneys, Earl Rögnvald’s claim to his share of the Islands being, however, reserved. Earl Harald (Maddadson) was thus denuded of all power in the Islands. He fled across to Caithness, but after a time he returned to the Orkneys with four ships and a hundred men, and after an unsuccessful attempt to surprise Erlend[38] he was obliged to abandon the enterprise for a time. Meanwhile, Erlend had carried off Harald’s mother Margaret (who seems to have been still a beautiful woman, though of very indifferent character), and fled with her to the island of Mousa in Shetland, where they fortified themselves in the old Pictish tower or borg of Mousa, which about two centuries before had given shelter during
