Just before dawn, the hour when the peasants hear his ghostly voice crying out, his pride awoke and he called loudly:  ’Winny, daughter of Dermott of the Sheep, if you do not come to me I will go and never return to the island of the Holy Trinity,’ and before his voice had died away a cold and whirling wind had swept over the island and he saw many figures rushing past, women of the Sidhe with crowns of silver and dim floating drapery; and then Oona, but no longer smiling gently, for she passed him swiftly and angrily, and as she passed struck him upon the face crying:  ‘Then go and never return.’

He would have followed, and was calling out her name, when the whole glimmering company rose up into the air, and, rushing together in the shape of a great silvery rose, faded into the ashen dawn.

Costello got up from the grave, understanding nothing but that he had made his beloved angry and that she wished him to go, and wading out into the lake, began to swim.  He swam on and on, but his limbs were too weary to keep him afloat, and her anger was heavy about him, and when he had gone a little way he sank without a struggle, like a man passing into sleep and dreams.

The next day a poor fisherman found him among the reeds upon the lake shore, lying upon the white lake sand with his arms flung out as though he lay upon a rood, and carried him to his own house.  And the very poor lamented over him and sang the keen, and when the time had come, laid him in the Abbey on Insula Trinitatis with only the ruined altar between him and Dermott’s daughter, and planted above them two ash-trees that in after days wove their branches together and mingled their trembling leaves.
