So it came to pass that, after four days' ride, Sir Galahad reached an abbey. Now Sir Galahad was still clothed in red armor as when he came to the king's court, and by his side hung the wondrous sword; but he was without a shield. They of the abbey received him right heartily, as also did the brave King Bagdemagus, Knight of the Round Table, who was resting there. When they had greeted each other, Sir Galahad asked King Bagdemagus what adventure had brought him there. "Sir," said Bagdemagus, "I was told that in this abbey was preserved a wondrous shield which none but the best knight in the world might bear without grievous harm to himself. And though I know well that there are better knights than I, to-morrow I purpose to make the attempt. But, I pray you, bide at this monastery awhile until you hear from me; and if I fail, do ye take the adventure upon you." "So be it," said Sir Galahad. The next day, at their request, Sir Galahad and King Bagdemagus were led into the church by a monk and shown where, behind the altar, hung the wondrous shield, whiter than snow save for the blood-red cross in its midst. Then the monk warned them of the danger to any who, being unworthy, should dare to bear the shield. But King Bagdemagus made answer: "I know well that I am not the best knight in the world, yet will I try if I may bear it." So he hung it about his neck, and bidding farewell, rode away with his squire. The two had not journeyed far before they saw a knight approach, armed all in white mail and mounted upon a white horse. Immediately he laid his spear in rest and, charging King Bagdemagus, pierced him through the shoulder and bore him from his horse; and standing over the wounded knight, he said: "Knight, thou hast shown great folly, for none shall bear this shield save the peerless knight, Sir Galahad." Then, taking the shield, he gave it to the squire, and said: "Bear this shield to the good Knight Galahad and greet him well from me." "What is your name?" asked the squire. "That is not for thee or any other to know." "One thing I pray you," said the squire; "why may this shield be borne by none but Sir Galahad without danger?" "Because it belongs to him only," answered the stranger knight, and vanished.
