Book II - Chapter XI - Of the interment of twelve kings, and of the prophecy of Merlin, and how Balin should give the dolorous stroke.
SO at the interment came King Lot's wife Margawse with her four sons, Gawaine, Agravaine, Gaheris, and Gareth. Also there came thither King Uriens, Sir Ewaine's father, and Morgan le Fay his wife that was King Arthur's sister. All these came to the interment. But of all these twelve kings King Arthur let make the tomb of King Lot passing richly, and made his tomb by his own; and then Arthur let make twelve images of latten and copper, and over-gilt it with gold, in the sign of twelve kings, and each one of them held a taper of wax that burnt day and night; and King Arthur was made in sign of a figure standing above them with a sword drawn in his hand, and all the twelve figures had countenance like unto men that were overcome. All this made Merlin by his subtle craft, and there he told the king, When I am dead these tapers shall burn no longer, and soon after the adventures of the Sangreal shall come among you and be achieved. Also he told Arthur how Balin the worshipful knight shall give the dolorous stroke, whereof shall fall great vengeance. Oh, where is Balin and Balan and Pellinore? said King Arthur. As for Pellinore, said Merlin, he will meet with you soon; and as for Balin he will not be long from you; but the other brother will depart, ye shall see him no more. By my faith, said Arthur, they are two marvellous knights, and namely Balin passeth of prowess of any knight that ever I found, for much beholden am I unto him; would God he would abide with me. Sir, said Merlin, look ye keep well the scabbard of Excalibur, for ye shall lose no blood while ye have the scabbard upon you, though ye have as many wounds upon you as ye may have. So after, for great trust, Arthur betook the scabbard to Morgan le Fay his sister, and she loved another knight better than her husband King Uriens or King Arthur, and she would have had Arthur her brother slain, and therefore she let make another scabbard like it by enchantment, and gave the scabbard Excalibur to her love; and the knight's name was called Accolon, that after had near slain King Arthur. After this Merlin told unto King Arthur of the prophecy that there should be a great battle beside Salisbury, and Mordred his own son should be against him. Also he told him that Bagdemegus was his cousin, and germain unto King Uriens.
