TITLE I.
Here the story is silent of Lancelot and Messire Gawain, and saith that Perceval is in the Turning Castle, whereof Joseus recounteth the truth, to wit, that Virgil founded it in the air by his wisdom in such fashion, when the philosophers went on the Quest of the Earthly Paradise, and it was prophesied that the castle should not cease turning until such time as the Knight should come thither that should have a head of gold, the look of a lion, a heart of steel, the navel of a virgin maiden, conditions without wickedness, the valour of a man and faith and belief of God; and that this knight should bear the shield of the Good Soldier that took down the Saviour of the World from hanging on the rood. It was prophesied, moreover, that all they of the castle and all other castles whereof this one was the guardian should hold the old law until such time as the Good Knight should come, by whom their souls should be saved and their death respited. For, so soon as he should be come, they should run to be baptized, and should firmly believe the new law. Wherefore was the joy great in the castle for that their death should now be respited, and that they should be released of all terror of the knight that was their foe, whom they dreaded even to the death, and of the sin of the false law whereof they had heretofore been attaint.
