Brian, Ur, and Urcar, the three sons of Turenn, were Dedanaan chiefs. They slew Kian, the father of Luga of the 149 Long Arms, who was grandson of Balor of the Evil Eye. Luga imposed an extraordinary eric fine on the sons of Turenn, part of which was “the cooking-spit of the women of Fincara.” For a quarter of a year Brian and his brothers sailed hither and thither over the wide ocean, landing on many shores, seeking tidings of the Island of Fincara. At last they met a very old man, who told them that the island lay deep down in the waters, having been sunk beneath the waves by a spell in times long past.

Then Brian put on his water-dress, with his helmet of transparent crystal on his head, telling his brothers to wait his return. He leaped over the side of the ship, and sank at once out of sight. He walked about for a fortnight down in the green salt sea, seeking for the Island of Fincara, and at last he found it.

His brothers waited for him in the same spot the whole time, and when he came not they began to fear he would return no more. At last they were about to leave the place, when they saw the glitter of his crystal helmet deep down in the water, and immediately after he came to the surface with the cooking-spit in his hand.––“Old Celtic Romances” (Joyce), p. 87.
