Nudd already discussed under his title Nodons, is less prominent than his son Gwyn, whose fight with Gwthur we have explained as a mythic explanation of ritual combats for the increase of fertility. He also appears as a hunter and as a great warrior,[415] "the hope of armies," and thus he may be a god of fertility who became a god of war and the chase. But legend associated him with Annwfn, and regarded him, like the Tuatha Déa, as a king of fairyland.[416] In the legend of S. Collen, the saint tells two men, whom he overhears speaking of Gwyn and the fairies, that these are demons. "Thou shalt receive a reproof from Gwyn," said one of them, and soon after Collen was summoned to meet the king of Annwfn on Glastonbury Tor. He climbed the hill with a flask of holy water, and saw on its top a splendid castle, with crowds of beautiful and youthful folk, while the air resounded with music. He was brought to Gwyn, who politely offered him food, but "I will not eat of the leaves of the tree," cried the saint; and when he was asked to admire the dresses of the crowd, all he would say was that the red signified burning, the blue coldness. Then he threw the holy water over them, and nothing was left but the bare hillside.[417] Though Gwyn's court on Glastonbury is a local Celtic Elysium, which was actually located there, the story marks the hostility of the Church to the cult of Gwyn, perhaps practised on hilltops, and this is further seen in the belief that he hunts souls of the wicked and is connected with Annwfn in its later sense of hell. But a mediant view is found in _Kulhwych_, where it is said of him that he restrains the demons of hell lest they should destroy the people of this world. In the _Triads_ he is, like other gods, a great magician and astrologer.[418]
