So Sir Tristram went in the direction King Angus had said, and a page showed him the way. So by and by he came to where the Lady Belle Isoult was, and it was a great chamber in a certain tower of the castle and high up Under the eaves of the roof.
How Lady Belle Isoult appeared to Sir Tristram.
The Lady Belle Isoult stood upon the farther side of this chamber so that the light from the windows shone full upon her face, and Sir Tristram perceived that she was extraordinarily beautiful, and rather like to a shining spirit than to a lady of flesh and blood. For she was clad altogether in white and her face was like to wax for whiteness and clearness, and she wore ornaments of gold set with shining stones of divers colors about her neck and about her arms so that they glistered with a wonderful lustre. Her eyes shone very bright and clear like one with a fever, and Sir Tristram beheld that there were channels of tears upon her face and several tears stood upon her white cheeks like to shining jewels hanging suspended there.
So, for a while, Sir Tristram stood still without speaking and regarded her from afar. Then after a while she spake and said, "Sir, what is this you have done?" "Lady," he said, "I have done what God set me to do, though I would rather die than do it."
She said, "Tristram, you have betrayed me." Upon the which he cried out in a very loud and piercing voice, "Lady, say not so!"
She said: "Tristram, tell me, is it better to fulfil this pledge you have made, knowing that in so doing you sacrifice both my happiness and your happiness to satisfy your pride of honor; or is it better that you sacrifice your pride and break this promise so that we may both be happy? Tristram, I beseech you to break this promise you have made and let us be happy together."
At this Sir Tristram cried out in a very loud voice: "Lady, did you put your hand into my bosom and tear my naked heart, you could not cause me so much pain as that which I this moment endure. It cannot be as you would have it, for it is thus with me: were it but myself whom I might consider, I would freely sacrifice both my life and my honor for your sake. But it may not be so, lady; for I am held to be one of the chiefest of that order of knighthood to which I belong, wherefore I may not consider myself, but must ever consider that order. For if I should violate a pledge given upon my knighthood, then would I dishonor not myself, but that entire order to which I belong. For, did I so, all the world would say, what virtue is there in the order of knighthood when one of the chiefest of that order may violate his pledge when it pleases him to do so? So, lady, having assumed that great honor of knighthood I must perform its obligations even to the uttermost; yea, though in fulfilling my pledge I sacrifice both Thee and myself."
Then Belle Isoult looked upon Sir Tristram for some little while, and by and by she smiled very pitifully and said: "Ah, Tristram, I believe I am more sorry for thee than I am for myself."
"Lady," said Tristram, "I would God that I lay here dead before you. But I am not able to die, but am altogether strong and hale--only very sorrowful at heart." And therewith he turned and left that place. Only when he had come to a place where he was entirely by himself with no one but God to see him, he hid his face in his hands and wept as though his heart were altogether broken. So it was that Sir Tristram fulfilled his pledge.
Belle Isoult and Sir Tristram depart for Cornwall.
