the chessboard, and when thou didst slay the black man of Ysbidinongyl, and when thou didst slay the stag, and when thou didst go to fight the black man of the cromlech. And I came with the bloody head in the salver, and with the lance that streamed with blood from the point to the hand, all along the shaft; and the head was thy cousin's, and he was killed by the sorceresses of Gloucester, who also lamed thine uncle; and I am thy cousin. And there is a prediction that thou art to avenge these things." Then Peredur and Gwalchmai took counsel, and sent to Arthur and his household, to beseech them to come against the sorceresses. And they began to fight with them; and one of the sorceresses slew one of Arthur's men before Peredur's face, and Peredur bade her forbear. And the sorceress slew a man before Peredur's face a second time, and a second time he forbad her. And the third time the sorceress slew a man before the face of Peredur; and then Peredur drew his sword, and smote the sorceress on the helmet; and all her head-armour was split in two parts. And she set up a cry, and desired the other sorceresses to flee, and told them that this was Peredur, the man who had learnt Chivalry with them, and by whom they were destined to be slain. Then Arthur and his household fell upon the sorceresses, and slew the sorceresses of Gloucester every one. And thus is it related concerning the Castle of Wonders.
