by my name, but by my nickname am I best known.” “And wilt thou tell us what thy nickname is?” “I will tell you; it is Iddawc Cordd Prydain.” “Ha, chieftain,” said Rhonabwy, “why art thou called thus?” “I will tell thee. I was one of the messengers between Arthur and Medrawd his nephew, at the battle of Camlan; and I was then a reckless youth, and through my desire for battle, I kindled strife between them, and stirred up wrath, when I was sent by Arthur the Emperor to reason with Medrawd, and to show him, that he was his foster-father and his uncle, and to seek for peace, lest the sons of the Kings of the Island of Britain, and of the nobles, should be slain. And whereas Arthur charged me with the fairest sayings he could think of, I uttered unto Medrawd the harshest I could devise. And therefore am I called Iddawc Cordd Prydain, for from this did the battle of Camlan ensue. And three nights before the end of the battle of Camlan I left them, and went to the Llech Las in North Britain to do penance. And there I remained doing penance seven years, and after that I gained pardon.” Then lo! they heard a mighty sound which was much louder than that which they had heard before, and when they looked round towards the sound, they beheld a ruddy youth, without beard or whiskers, noble of mien, and mounted on a stately courser. And from the shoulders and the front of the knees downwards the horse was bay. And upon the man was a dress of red satin wrought with yellow silk, and yellow were the borders of his scarf. And such parts of his apparel and of the trappings of his horse as were yellow, as yellow were they as the blossom of the broom, and such as were red, were as ruddy as the ruddiest blood in the world. Then, behold the horseman overtook them, and he asked of Iddawc a share of the little men that were with him. “That which is fitting for me to grant I will grant, and thou shalt be a companion to them as I have been.” And the horseman went away. “Iddawc,” inquired Rhonabwy, “who was that horseman?” “Rhuvawn Pebyr the son of Prince Deorthach.” And they journeyed over the plain of Argyngroeg as far as the ford of Rhyd y Groes on the Severn. And for a mile around the ford on both sides of the road, they saw tents and encampments, and there was the clamour of a mighty host. And they came to the edge of the ford, and there they beheld Arthur sitting on a flat island below the ford, having Bedwini the Bishop on one side of him, and Gwarthegyd the son of Kaw on the other. And a tall, auburn-haired youth stood before him, with his sheathed sword in his hand, and clad in a coat and cap of jet-black satin. And his face was white as ivory, and his eyebrows black as jet, and such part of his wrist as could be seen between his glove and his sleeve, was whiter than the lily, and thicker than a warrior’s ankle.
