After the fatal battle of Gavra, in which most of the Feni were killed, Usheen and his father, the king, and some of the survivors of the battle were hunting the deer with their dogs, when they met a maiden riding on a slender white horse with hoofs of gold, and with a golden crescent between his ears. The maiden's hair was of the color of citron and was gathered in a silver band; and she was clad in a white garment embroidered with strange devices. She asked them why they rode slowly and seemed sad, and not like other hunters; and they replied that it was because of the death of their friends and the ruin of their race. When they asked her in turn whence she came, and why, and whether she was married, she replied that she had never had a lover or a husband, but that she had crossed the sea for the love of the great hero and bard Usheen, whom she had never seen. Then Usheen was overcome with love for her, but she said that to wed her he must follow her across the sea to the Island of Perpetual Youth. There he would have a hundred horses and a hundred sheep and a hundred silken robes, a hundred swords, a hundred bows, and a hundred youths to follow him; while she would have a hundred maidens to wait on her. But how, he asked, was he to reach this island? He was to mount her horse and ride behind her. So he did this, and the slender white horse, not feeling his weight, dashed across the waves of the ocean, which did not yield beneath his tread. They galloped across the very sea, and the maiden, whose name was Niam, sang to him as they rode, and this so enchantingly that he scarcely knew whether hours passed or days. Sometimes deer ran by them over the water, followed by red-eared hounds in full chase; sometimes a maiden holding up an apple of gold; sometimes a beautiful youth; but they themselves rode on always westward. At last they drew near an island which was not, Niam said, the island they were seeking; but it was one where a beautiful princess was kept under a spell until some defender should slay a cruel giant who held her under enchantment until she should either wed him or furnish a defender. The youth Usheen, being an Irishman and not easily frightened, naturally offered his services as defender, and they waited three days and nights to carry on the conflict. He had fought at home--so the legend says--with wild boars, with foreign invaders, and with enchanters, but he never had quite so severe a contest as with this giant; but after he had cut off his opponent's head and had been healed with precious balm by the beautiful princess, he buried the giant's body in a deep grave and placed above it a great stone engraved in the Ogham alphabet--in which all the letters are given in straight lines.
