The legend of the Lady of the Wood is contained in the Iolo MSS., and is of considerable antiquity. It is a most fascinating tale: Einion, the son of Gwalchmai, 'was one fine summer morning walking in the woods of Treveilir,' when 'he beheld a graceful slender lady of elegant growth, and delicate feature, and her complexion surpassing every white and red in the morning dawn and the mountain snow, and every beautiful colour in the blossoms of wood, field, and hill. And then he felt in his heart an inconceivable commotion of affection, and he approached her in a courteous manner, and she also approached him in the same manner; and he saluted her, and she returned his salutation; and by these mutual salutations he perceived that his society was not disagreeable to her. He then chanced to cast his eye upon her foot, and he saw that she had hoofs instead of feet, and he became exceedingly dissatisfied,' as well he might. But the lady gave him to understand that he must pay no attention to this trifling freak of nature. 'Thou must,' she said, 'follow me wheresoever I go, as long as I continue in my beauty.'

And after being a long time, he knew not how long, with the goblin, the Lady of the Wood, he looked one morning as the sun was rising upon the half of the ring, and he bethought him to place it in the most precious place he could, and he resolved to put it under his eyelid; and as he was endeavouring to do so, he could see a man in white apparel, and mounted on a snow-white horse, coming towards him, and that person asked him what he did there; and he told him that he was cherishing an afflicting remembrance of his wife Angharad. "Dost thou desire to see her?" said the man in white. "I do," said Einion, "above all things, and all happiness of the world." "If so," said the man in white, "get upon this horse, behind me;" and that Einion did, and looking around he could not see any appearance of the Lady of the Wood, the goblin, excepting the track of hoofs of
