Nephew of King Mark of Cornwall, Tristan was one of the great lovers in Celtic mythology. He was escorting Isolde to Cornwall to marry the King, when they accidentally drank a love portion prepared by Isolde's mother, the Irish queen. They fell desperately in love. In the end they agreed to separate and Tristan went to Brittany where later he was seriously wounded. He sent for help from Isolde, who had cured him once before, of a wound. She sailed for Brittany with the magic potion, however a mix-up in the signals from the ship led Tristan to believe that she was not aboard and he lost the will to live and died of his wound. When Isolde was told of her lover's death she died of a broken heart.
