Son of Nudd; called the Sparrowhawk. He ousted the Earl of Yniol from his earldom, and tried to win Enid, the earls daughter, but failing in this, became the evil genius of the gentle earl. Being overthrown in a tournament by Prince Geraint, he was sent to the court of King Arthur, where his whole nature was completely changed, and subdued to that gentleness which, when it weds with manhood, makes a man. (Idylls of the King; Enid.)
