To illustrate the history of the island I select the following episode from _Barbaric Tales_. It deals with The Flight of the Culdees. The name culdee is somewhat loosely used both by mediæval and modern writers, for it does not appear to have been given to the Brotherhood of the Columban Church till two hundred years after Columba's death. The word may be taken to mean the Cleric of God; perhaps, later, it was the equivalent of anchorite. This episode is, in date, about A.D. 800 or soon after. On the wane of the moon, on the day following the ruin of Bail'-tiorail, sails were seen far east of Stromness. Olaus the White called his men together. The boats coming before the wind were doubtless his own galleys which he had lost when the south-gale had blown them against Skye; but no man can know when and how the gods may smile grimly, and let the swords that whirl be broken, or the spears that are flat become a hedge of death. An hour later, a startled word went from viking to viking. The galleys in the offing were the fleet of Sweno the Hammerer. Why had he come so far southward, and why were oars so swift and the stained sails distended before the wind? They were soon to know. Sweno himself was the first to land. A great man he was, broad and burly, with a sword-slash across his face that brought his brows in a perpetual frown above his savage blood-shot eyes. In few words he told how he had met a galley, with only half its crew, and of these many who were wounded. It was the last of the fleet of Haco the Laugher. A fleet of fifteen war-birlinns had set out from the Long Island, and had given battle. Haco had gone into the strife, laughing loud as was his wont, and he and all his men had the berserk rage, and fought with joy and foam at the mouth. Never had the Sword sung a sweeter song. "Well," said Olaus the White grimly, "well, how did the Raven fly?" "When Haco laughed for the last time, his sword waving out of the death-tide where he sank, there was only one galley left. No more than nine vikings lived thereafter to tell the tale. These nine we took out of their boat, which was below waves soon. Haco and his men are all fighting the sea-shadows by now." A loud snarling went from man to man. This became a cry of rage. Then savage shouts filled the air. Swords were lifted up against the sky; and the fierce glitter of blue eyes and the bristling of tawny beards were fair to see, thought the captive women, though their hearts beat in their breasts like eaglets behind the bars of a cage. Sweno the Hammerer frowned a deep frown when he heard that Olaus was there with only the _Svart-Alf_ out of the galleys which had gone the southward way. "If the islanders come upon us now with their birlinns we shall have to make a running fight," he said. Olaus laughed. "Ay, but the running shall be after the birlinns, Sweno." "I hear there are fifty and nine men of these Culdees yonder under the sword-priest, Maoliosa?"
