So leave we Sir Gareth there with Sir Gringamore and his sisters, and turn we unto King Arthur, that at the next feast of Pentecost held his feast; and there came the Green Knight with fifty knights, and yielded them all unto King Arthur. And so there came the Red Knight his brother, and yielded him to King Arthur, and three score knights with him. Also there came the Blue Knight, brother to them, with an hundred knights, and yielded them unto King Arthur; and the Green Knight’s name was Pertolepe, and the Red Knight’s name was Perimones, and the Blue Knight’s name was Sir Persant of Inde. These three brethren told King Arthur how they were overcome by a knight that a damosel had with her, and called him Beaumains. Jesu, said the king, I marvel what knight he is, and of what lineage he is come. He was with me a twelvemonth, and poorly and shamefully he was fostered, and Sir Kay in scorn named him Beaumains. So right as the king stood so talking with these three brethren, there came Sir Launcelot du Lake, and told the king that there was come a goodly lord with six hundred knights with him.
