Now of all those places whereunto he wandered, Sir Tristram found most pleasure in the pleasance of the castle where was a fair garden and fruit trees; for it was there that he and the Lady Belle Isoult had walked together aforetime ere his affliction had befallen him, and he remembered this place better than any other, and took more pleasure in it. Now one day Sir Tristram came wandering thus into that pleasance and, the day being warm, he sat under the shade of an appletree beside a marble fountain of water; and the appletree above his head was all full of red and golden fruit. So Sir Tristram sat there, striving to remember how it was that he had once aforetime beheld that fountain and that garden and that appletree beneath which he sat.
So whilst he sat there pondering in that wise, there came the Lady Belle Isoult into the garden of that pleasance and her lady, the dame Bragwaine, was with her, and the hound, hight Houdaine, which Sir Tristram had sent to her by Gouvernail, walked beside her on the other side. Then Belle Isoult perceived that there was a man sitting under the appletree, and she said to dame Bragwaine: "Who is yonder man who hath dared to come hither into our privy garden?" Unto this, dame Bragwaine replied: "That, lady, is the gentle madman of the forest whom Sir Launcelot brought hither two days ago."
Then the Lady Belle Isoult said, "Let us go nearer and see what manner of man he is"; and so they went forward toward where Sir Tristram sat, and the dog Houdaine went with them.
Then Sir Tristram was aware that someone was nigh; and therewith he turned his face and beheld the Lady Isoult for the first time since he had gone mad in the forest; and the lady was looking at him, but knew him not.
Then of a sudden, because of his great love for Belle Isoult, the memory of Sir Tristram came all back to him in the instant, and upon that instant he knew who he was and all that had befallen him, and how he had been brought there as a madman out of the forest. But though he knew her in that wise, yet, as has been said, she knew not him.
Then Sir Tristram was all overwhelmed with shame that he should be thus found by that dear lady; wherefore he turned away his face and bowed his head so that she might not remember him, for he perceived that as yet she did not know him who he was.
Now at that moment the dog, Houdaine, was aware of the savor of Sir Tristram; wherefore he leaped away from the Lady Belle Isoult and ran to Sir Tristram and smelt very eagerly of him. And with that he knew his master.
Houdaine knoweth Sir Tristram.
Then the two ladies who looked beheld Houdaine fall down at the feet of Sir Tristram and grovel there with joy. And they beheld that he licked Sir Tristram's feet and his hands, and that he leaped upon Sir Tristram and licked his neck and face, and at that they were greatly astonished.
Then of a sudden a thought came to dame Bragwaine, and she catched the Lady Isoult by the arm and she said: "Lady, know you not who yonder madman is?" But the Lady Belle Isoult said: "Nay, I know not who he is. Who is he, Bragwaine?" And Bragwaine said: "Certes, that is Sir Tristram, and no one else in all the world."
