So the queen and the knights of the court and the common people made much of Sir Tristram wheresoever he went; but the joy that La Belle Isoude had in her heart no tongue may tell. When Sir Tristram was led to her and they met after so long an absence from each other, men saw the lovely face light up with so sweet and high a look that they marvelled at her beauty. Yet they saw how straitly Sir Tristram held himself, and made not much of his meeting with her and did not seek her company. Then on a day King Anguish asked Sir Tristram what was the boon he craved. 'But whatever it be,' said the king, 'it is yours without fail.' Sir Tristram's face went hard and white, and after a little while he said: 'It is this, my lord. I bear a request from my uncle, King Mark, and it is that you give him your daughter La Belle Isoude for his wife, and ye let me take her unto him, for so I have promised him.' 'Alas,' said the king, and looked full heavily into the eyes of Sir Tristram, 'I had liefer than all the land that I have that ye should wed her yourself.' Sir Tristram turned away, and made this reply: 'I have given my promise, and I were ashamed for ever in the world if I did aught else. I require you to hold to your promise, and to let your daughter depart with me to be wedded to my uncle, King Mark.' 'As I have promised, so will I do,' said the king. 'But I let you know 'tis with a heavy heart.' Nor would the king say more, knowing that he might make bad worse. But the surprise and grief of La Belle Isoude, when she knew that Sir Tristram was to take her to be wife not unto himself but to a stranger, what tongue may tell and what words may say? Nightly, on the days when she was being prepared to depart, she wept full sorely in the arms of her mother or of Bragwine her faithful gentlewoman; but in hall or abroad she was ever calm and cold, though pale. The queen, her mother, feared much of this marriage, and so sent a swift message to a great witch who dwelled in a dark wet valley in the midst of the Purple Hills, and for much gold a potent philtre was prepared. Then, on the day when, with much weeping and many sad farewells, La Belle Isoude with her gentlewomen and many noble ladies and knights were to go into the ship, the queen called Bragwine aside, and giving her a little golden flasket, said to her: 'Take this with thee, Bragwine, for I misdoubt this marriage overmuch, and I charge thee do this. On the day that King Mark shall wed my daughter, do thou mix this drink in their wine in equal parts, and then I undertake that each shall love the other alone all the days of their lives.'
