When he awoke therefrom he was crazed, and ran into the forest and abode there like a wild man many days; whereby he waxed lean and weak of body, and would have died, but that a hermit laid some meat beside him as he slept. Now in that forest was a giant named Tauleas, who, for fear of Tristram, had hid himself within a castle, but when they told him he was mad, came forth and went at large again. And on a certain day he saw a knight of Cornwall, named Sir Dinaunt, pass by with a lady, and when he had alighted by a well to rest, the giant leaped out from his ambush, and took him by the throat to slay him. But Sir Tristram, as he wandered through the forest, came upon them as they struggled; and when the knight cried out for help, he rushed upon the giant, and taking up Sir Dinaunt’s sword, struck off therewith the giant’s head, and straightway disappeared among the trees.
Anon, Sir Dinaunt took the head of Tauleas, and bare it with him to the court of King Mark, whither he was bound, and told of his adventures. “Where had ye this adventure?” said King Mark.
“At a fair fountain in thy forest,” answered he.
“I would fain see that wild man,” said the king.
So within a day or two he commanded his knights to a great hunting in the forest. And when the king came to the well, he saw a wild man lying there asleep, having a sword beside him; but he knew not that it was Sir Tristram. Then he blew his horn, and summoned all his knights to take him gently up and bear him to the court.
And when they came thereto they bathed and washed him, and brought him somewhat to his right mind. Now La Belle Isault knew not that Sir Tristram was in Cornwall; but when she heard that a wild man had been found in the forest, she came to see him. And so sorely was he changed, she knew him not. “Yet,” said she to Dame Bragwaine, “in good faith I seem to have beheld him ofttimes before.”
As she thus spoke a little hound, which Sir Tristram had given her when she first came to Cornwall, and which was ever with her, saw Sir Tristram lying there, and leapt upon him, licking his hands and face, and whined and barked for joy.
“Alas,” cried out La Belle Isault, “it is my own true knight, Sir Tristram.”
And at her voice Sir Tristram’s senses wholly came again, and wellnigh he wept for joy to see his lady living.
But never would the hound depart from Tristram; and when King Mark and other knights came up to see him, it sat upon his body and bayed at all who came too near. Then one of the knights said, “Surely this is Sir Tristram; I see it by the hound.”
