Then the king [caused that Queen Guenever should see Sir Galahad] in the visage; and when she beheld him she said, "Soothly I dare well say that he is Sir Launcelot's son, for never two men resembled more in likeness, therefore it is no marvel though he be of great prowess."
So a lady that stood by the queen said: "Madam, for God's sake, ought he of right to be so good a knight?"
"Yea, forsooth," said the queen, "for he is of all parties come of the best knights of the world, and of the highest lineage, for Sir Launcelot is come but of the eighth degree from our Lord Jesu Christ, and Sir Galahad is of the ninth degree from our Lord Jesu Christ, therefore I dare well say that they be the greatest gentlemen of all the world."
And then the king and all the estates went home unto Camelot, and so went to even-song to the great minster; and so after that they went to supper, and every knight sat in their place as they were beforehand. Then anon they heard cracking and crying of thunder, that them thought the place should all to-rive [burst]; in the midst of the blast entered a sunbeam more clear by seven times than ever they saw day, and all they were alighted of the grace of the Holy Ghost. Then began every knight to behold other, and either saw other by their seeming fairer than ever they saw afore, [and] there was no knight that might speak one word a great while, and so they looked every man on other, as they had been dumb. Then there entered into the hall the Holy Grail covered with white samite, but there was none might see it, nor who bare it. And there was all the hall full filled with good odors, and every knight had such meats and drinks as he best loved in this world; and when the Holy Grail had been borne through the hall, then the holy vessel departed suddenly, that they wist not where it became. Then had they all breath to speak. And then the king yielded thankings unto God of His good grace that He had sent them.
"Now," said Sir Gawaine, "we have been served this day of what meats and drinks we thought on, but one thing beguiled us, we might not see the Holy Grail, it was so preciously covered: wherefore I will make here avow, that to-morn, without longer abiding, I shall labor in the quest of the Sancgreal, that I shall hold me out a twelvemonth and a day, or more if need be, and never shall I return again unto the court till I have seen it more openly than it hath been seen here: and if I may not speed, I shall return again as he that may not be against the will of our Lord Jesu Christ."
When they of the Table Round heard Sir Gawaine say so, they arose up the most part, and made such avows as Sir Gawaine had made.
Anon as King Arthur heard this he was greatly displeased, for he wist well that they might not gainsay their avows.
"Alas!" said King Arthur unto Sir Gawaine, "ye have nigh slain me with the avow and promise that ye have made. For through you ye have bereft me of the fairest fellowship and the truest of knighthood that ever were seen together in any realm of the world. For when they depart from hence, I am sure they all shall never meet more in this world, for they shall die many in the quest. And so it forethinketh [repenteth] me a little, for I have loved them as well as my life, wherefore it shall grieve me right sore the departing of this fellowship. For I have had an old custom to have them in my fellowship."
