Anon Sir Lancelot heard a voice: “Leave now thy ship and go within the castle, and thou shalt see a part of thy desire.”
Then he armed and went towards the gate, and coming to the lions he drew out his sword, but suddenly a dwarf rushed out and smote him on the arm, so that he dropt his sword, and heard again the voice, “Oh, man of evil faith, and poor belief, wherefore trustest thou thine arms above thy Maker?” Then he put up his sword and signed the cross upon his forehead, and so passed by the lions without hurt.
And going in, he found a chamber with the door shut, which in vain he tried to open. And listening thereat he heard a voice within, which sang so sweetly that it seemed no earthly thing, “Joy and honour be to the Father of Heaven!” Then he kneeled down at the door, for he knew well the Sangreal was there within.
Anon the door was opened without hands, and forthwith came thereout so great a splendour as if all the torches of the world had been alight together. But when he would have entered in, a voice forbad him; wherefore he drew back, and looked, standing upon the threshold of the door. And there he saw a table of silver, and the holy vessel covered with red samite, and many angels round it holding burning candles and a cross and all the ornaments of the altar.
Then a priest stood up and offered mass, and when he took the vessel up, he seemed to sink beneath that burden. At that Sir Lancelot cried, “O Father, take it not for sin that I go in to help the priest, who hath much need thereof.” So saying, he went in, but when he came towards the table he felt a breath of fire which issued out therefrom and smote him to the ground, so that he had no power to rise.
Then felt he many hands about him, which took him up and laid him down outside the chapel door. There lay he in a swoon all through that night, and on the morrow certain people found him senseless, and bore him to an inner chamber and laid him on a bed. And there he rested, living, but moving no limbs, twenty-four days and nights.
On the twenty-fifth day he opened his eyes and saw those standing round, and said, “Why have ye waked me? for I have seen marvels that no tongue can tell, and more than any heart can think.”
Then he asked where he was, and they told him, “In the Castle of Carbonek.”
“Tell your lord, King Pelles,” said he, “that I am Sir Lancelot.”
At that they marvelled greatly, and told their lord it was Sir Lancelot who had lain there so long.
