Then in an instant the lady who sat beside him shrieked very loud and shrill, and all about him was confusion and turbulence. And Sir Percival looked, and behold! it was not a strange and beautiful lady who sat beside him like a wonderful goddess, but it was the Enchantress Vivien, clad in red and bedecked with her jewels. For it was she who had thus planned the undoing of Sir Percival by causing him to sin.

Then Sir Percival cried, “Hah! Is it thou who wouldst betray me?” And therewith he reached for his sword which he had laid aside. Then, seeing what he intended, the Enchantress Vivien shrieked again, and she smote her hands together, and in that instant she disappeared, and all her attendants disappeared, and the pavilion and the table and all of the feast and wine disappeared, and the boat in which she had come disappeared, and Sir Percival found himself sitting alone upon the seaside.

Then Sir Percival kneeled down and he set his hands together and he prayed. And he said, “O God! how hast thou saved thy servant by means of a floating thought? For the thought of that which was sacred and holy hath purged my sin that was very close to me.” And he said, “How shall I thank thee for this; for lo! I trod upon a crust so thin that, had I borne even a part of my weight upon it, I would have fallen through that crust as into a lake of fire.”

So he prayed for a long time and by and by he was comforted. Then he arose and stood up, and he girded his sword tight about him. And he cast his eyes all around and he beheld that he was alone and in a very desolate place. And, at that time, the full moon was shining very brightly.

Anon he beheld in the gloom of the distance an object that approached very rapidly. And this object also was a boat, but there was no one in it.

And when the boat approached nigh enough he beheld that there was a couch within it, and that the couch was covered with white linen. But no other thing was in the boat but that.

Then Sir Percival said, “What is this? Is there a sin also in this, or is it without sin?” And he said, “If this be sin, then let it declare itself,” and therewith he marked the sign of the cross upon his forehead.

But there followed not any malignant sign after that, but the boat remained there where it was.

Sir Percival entereth a boat.

Then Sir Percival perceived that it was intended for him to enter that boat, and he did enter it. And at that time the moon had arisen very full and round. And the moon shone down upon the earth with a wonderful radiance. So that what with the light in the sky from the moonlight, it was as though a strange and magical radiance embalmed the entire earth.
