           CHAPTER II. How the Knights of the Round Table were ordained
                 and their sieges blessed by the Bishop of Canterbury.

    WHEN King Arthur heard of the coming of Guenever and the hundred knights with the Table Round, then King Arthur made great joy for her coming, and that rich present, and said openly, This fair lady is passing welcome unto me, for I have loved her long, and therefore there is nothing so lief to me. And these knights with the Round Table please me more than right great riches. And in all haste the king let ordain for the marriage and the coronation in the most honourable wise that could be devised. Now, Merlin, said King Arthur, go thou and espy me in all this land fifty knights which be of most prowess and worship. Within short time Merlin had found such knights that should fulfil twenty and eight knights, but no more he could find. Then the Bishop of Canterbury was fetched, and he blessed the sieges with great royalty and devotion, and there set the eight and twenty knights in their sieges. And when this was done Merlin said, Fair sirs, ye must all arise and come to King Arthur for to do him homage; he will have the better will to maintain you. And so they arose and did their homage, and when they were gone Merlin found in every sieges letters of gold that told the knights names that had sitten therein. But two sieges were void. And so anon came young Gawaine and asked the king a gift. Ask, said the king, and I shall grant it you. Sir, I ask that ye will make me knight that same day ye shall wed fair Guenever. I will do it with a good will, said King Arthur, and do unto you all the worship that I may, for I must by reason ye are my nephew, my sister's son.
