The Romance of Tristan and Iseult

Then Tristan went out to find Urgan in his lair, and they fought hard and long, till courage conquered strength, and Tristan, having cut off the giant's hand, bore it back to the Duke.

And "Sire," said he, "since I may choose a reward according to your word, give me the little fairy dog. It was for that I conquered Urgan, and your promise stands."

"Friend," said the Duke, "take it, then, but in taking it you take away also all my joy."

Then Tristan took the little fairy dog and gave it in ward to a Welsh harper, who was cunning and who bore it to Cornwall till he came to Tintagel, and having come there put it secretly into Brangien's hands, and the Queen was so pleased that she gave ten marks of gold to the harper, but she put it about that the Queen of Ireland, her mother, had sent the beast. And she had a goldsmith work a little kennel for him, all jewelled, and incrusted with gold and enamel inlaid; and wherever she went she carried the dog with her in memory of her friend, and as she watched it sadness and anguish and regrets melted out of her heart.

At first she did not guess the marvel, but thought her consolation was because the gift was Tristan's, till one day she found that it was fairy, and that it was the little bell that charmed her soul; then she thought: "What have I to do with comfort since he is sorrowing? He could have kept it too and have forgotten his sorrow; but with high courtesy he sent it to me to give me his joy and to take up his pain again. Friend, while you suffer, so long will I suffer also."

And she took the magic bell and shook it just a little, and then by the open window she threw it into the sea.
