Therewithal came the King with the Hundred Knights, and hard began to assail Sir Tristram. Let be, said Sir Galahad, be ye not so hardy to touch him, for I have given this knight his life. That is your shame, said the King with the Hundred Knights; hath he not slain your father and your mother? As for that, said Sir Galahad, I may not wite him greatly, for my father had him in prison, and enforced him to do battle with him; and my father had such a custom that was a shameful custom, that what knight came there to ask harbour his lady must needs die but if she were fairer than my mother; and if my father overcame that knight he must needs die. This was a shameful custom and usage, a knight for his harbour-asking to have such harbourage. And for this custom I would never draw about him. So God me help, said the King, this was a shameful custom. Truly, said Sir Galahad, so seemed me; and meseemed it had been great pity that this knight should have been slain, for I dare say he is the noblest man that beareth life, but if it were Sir Launcelot du Lake. Now, fair knight, said Sir Galahad, I require thee tell me thy name, and of whence thou art, and whither thou wilt.
