So they were married with great rejoicings, and all the kingdom was glad, and so was Sir Tristram, for now, he thought, he could quench that fatal love for Iseult of Cornwall, and could spend the rest of his days in this sunny land, happy with his sweet child-wife.

Alas! alas! Once more the deadly love-drink did its work! No sooner had he placed the ring on his bride's finger, than the love for the other Iseult returned stronger than ever.

"I have been false to my lady!" he cried to himself remorsefully, "for I swore ever to be her true knight, loyal to her alone." And such sorrow and repentance filled his heart that his love for his bride was killed. He concealed his pain so well, though, that little Iseult was happy, never doubting that her husband loved her,—but all the days and nights that passed were full for Tristram of yearning for his love, and a great longing to be again in Cornwall.

At last one day there arrived at the castle a knight from King Arthur's court at Camelot; and of him Sir Tristram asked, "Say they aught of me at court?"

"Truly," answered the knight, "they speak of you with shame, for Sir Launcelot says you are a false knight to your lady, and his love for you is dead, so that he longs to meet with you that he may joust with you."

Sore troubled indeed was Sir Tristram at this, for he loved Sir Launcelot, and coveted his respect, and to be deemed traitor to the lady for whom he would have laid down his life, hurt him most of all.

From that time his longing to return to Tintagel and his love for La Belle Iseult grew daily more and more unconquerable, until at last he could no longer bear it, and one day set sail from Brittany, leaving his poor little lonely wife behind to mourn his absence, and yearn for his return; for as yet she had not found out that there was no love at all in his heart for her.

But on a day soon after he had left her there was brought to her the story of his love for that other Iseult, and of hers for him. Then was the young wife filled with shame that ever she had showed her love for him, and jealousy raged in her, turning her love to bitter hate, and her heart hardened so that night and day she longed to be revenged.

Thus a whole year passed away, and Tristram and Queen Iseult loved each other as dearly as ever; but King Mark in his jealous anger kept them so watched that they could never see or speak one to the other, and they had no peace or joy in life, until at last they could bear the pain no longer, and one day they managed to escape together and to reach the Castle of Joyous Gard, where the king had no power to reach them, even had he known where they were hid. Of their love and happiness there no tongue can tell, and of the peace and joy of their life, for they loved each other above all else, and when they were together nothing had power to pain them.

But at last, on a sad, sad day, the trusty Gouvernail came to Sir Tristram with word that a summons had been sent him from King Arthur, to go to the aid of Sir Triamour of Wales, for he was sore beset by a monster named Urgan, and needed help.
