Here the story says that when Merlin saw that Gawainet and his companions had gone to Bredigan, he was very glad, for he was well aware that the two brothers Yvonet the Bastard and Yvonet the Great had left the castle of Arundel, and he knew that they were in grave danger of being killed or taken prisoner. Then he took on the likeness of a young man who was running, and he bore sealed letters in a shield painted with the arms of King Urien. He kept running until he got to Bredigan, and he was weary from the race. He had a garland of flowers on his head and held a long staff in his hand. He wore low buckled shoes and black silk hose and was dressed in a cotton robe, black with gold threads and gold bindings that were on the hood and sleeves, too, and at his waist was a white belt worked with iron and brass. He was tall and swarthy and had no beard, and between his shoulders a felt hat was hanging from his neck.
