who sets forth the beauties of that virtue for which the original Celtic paradise, with its unfailing ale and rivers of mead and wine, would hardly seem to have been the best possible school. Save for Spenser, all authorities agree in making Gwyn the determined opponent of things Christian. A curious and picturesque legend[550] is told of him in connection with St. Collen, who was himself the great-grandson of Brân’s son, Caradawc. The saint, desirous of still further retirement from the world, had made himself a cell beneath a rock near Glastonbury Tor, in Gwyn’s own “island of Avilion”. It was close to a road, and one day he heard two men pass by talking about Gwyn son of Nudd, and declaring him to be King of Annwn and the fairies. St. Collen put his head out of the cell, and told them to hold their tongues, and that Gwyn and his fairies were only demons. The two men retorted by warning the saint that he would soon have to meet the dark ruler face to face. They passed on, and not long afterwards St. Collen heard someone knocking at his door. On asking who was there, he got the answer: “I am here, the messenger of Gwyn ap Nudd, King of Hades, to bid thee come by the middle of the day to speak with him on the top of the hill.” The saint did not go; and the messenger came a second time with the same message. On the third visit, he added a threat that, if St. Collen did not come now, it would be the worse for him. So, a little disquieted, he went, but not unarmed. He consecrated some water, and took it with him. On other days the top of Glastonbury Tor had always been bare, but on this occasion the saint found it crowned by a splendid castle. Men and maidens, beautifully dressed, were going in and out. A page received him and told him that the king was waiting for him to be his guest at dinner. St. Collen found Gwyn sitting on a golden chair in front of a table covered with the rarest dainties and wines. He invited him to share them, adding that if there was anything he especially liked, it should be brought to him with all honour. “I do not eat the leaves of trees,” replied the saint, who knew what fairy meats and drinks were made of. Not taken aback by this discourteous answer, the King of Annwn genially asked the saint if he did not admire his servants’ livery, which was a motley costume, red on one side and blue on the other. “Their dress is good enough for its kind,” said St. Collen. “What kind is that?” asked Gwyn. “The red shows which side is being scorched, and the blue shows which side is being frozen,” replied the saint, and, splashing his holy water all round him, he saw castle, serving-men, and king vanish, leaving him alone on the bare, windy hill-top.
