In Arthurian legend, the knight, Tristram, received his name at birth and was told that his name reflected his life: sad or melancholy. Certainly, that is the case. He joined Arthur's Round Table, but his true story is linked with Isode, who became the wife of King Mark of Cornwall, but she is fated to fall in love with Tristram due to a "love potion" that Tristram and Isode accidentally drank. Mark is Tristram's uncle and the young lover is torn between loyalty to Mark and his love for Isolde. Their love ends tragically and has served as a basis for countless poems, a Wagnerian opera and a number of novels.
