Perceval, as the history telleth, was much honoured at the castle of the Queen of the Maidens, that was right passing fair. The Queen loved him of a passing great love, but well she knew that she should never have her desire, nor any dame nor damsel that might set her intent thereon, for chaste was he and in chastity was fain to die. So long was he at the castle as that he heard tell his uncle was arrived at the island whither he wont to come. Perceval maketh arm him forthwith and entereth into a galley below the hall, and maketh him be rowed toward his uncle, that much marvelleth when he seeth him coming, for never aforetime durst no knight issue out alone from this castle to meet him, nor to come there where he was, body to body. But had he known that it was Perceval, he would not have marvelled. Thereupon the galley taketh the ground and Perceval is issued forth. The Queen and the knights and her maidens are come to the windows of the castle to behold the bearing of the nephew and the uncle. The Queen would have sent over some of her knights with him, but Perceval would not. The King of Castle Mortal was tall and strong and hardy. He seeth his nephew come all armed, but knoweth him not. But Perceval knew him well, and kept his sword drawn and his shield on his arm, and sought out his uncle with right passing wrathfulness, and dealeth him a heavy buffet above upon his helm that he maketh him stoop withal. Howbeit, the King spareth him not, but smiteth him so passing stoutly that he had his helm all dinted in thereby. But Perceval attacketh him again, thinking to strike him above on the head, but the King swerveth aside and the blow falleth on the shield and cleaveth it right down as far as the boss. The King of Castle Mortal draweth him backward and hath great shame within himself for that Perceval should thus fettle him, for he searcheth him with his sword in every part, and dealeth him great buffets in such sort that, and his habergeon had not been so strong and tough, he would have wounded him in many places. IV. The King himself giveth him blows so heavy that the Queen and all they that were at the windows marvelled how Perceval might abide such buffets. The King took witting of the shield that Perceval bare, and looketh on it of a long space. "Knight," saith he, "who gave you this shield, and on behalf of whom do you bear such an one?" "I bear it on behalf of my father," saith he. "Did your father, then, bear a red shield with a white hart?" "Yea," saith Perceval, "Many a day." "Was your father, then, King Alain of the Valleys of Camelot?" "My father was he without fail. No blame ought I to have of him, for a good knight was he and a loyal." "Are you the son of Yglais my sister, that was his wife?" "Yea!" saith Perceval. "Then are you my nephew," saith the King of Castle Mortal, "For she was my sister."
