Tristan and Iseult’s conflict of love and loyalty is one of the classic tales of Western literature; in the Arthurian tradition, their tragic tragectory rivals and complements that of Lancelot and Guinevere. The basic story is one of mis-directed love: Tristan, the heroic nephew of King Mark of Cornwall, is sent to Ireland to escort the Irish king’s daughter, the beautiful Iseult, to Cornwall to become his uncle’s bride. In most versions, it is during the return voyage that Tristan and Iseult accidentally consume a love potion (meant to ensure Iseult’s happiness with Mark) together, and fall in love. Because Iseult’s engagement to Mark cannot be broken, she marries the king despite her love for Tristan, and the two lovers spend the rest of their lives attempting to satisfy their desire for each other without revealing that desire to Mark and the Cornish court. The tale of potion-induced passion has proved irresistable to artists in all media, from literature to visual arts to music, to the point that Wagner’s opera Tristan und Isolde is now more famous than the text on which it is based, the thirteenth century Tristan and Isolde of Gottfried von Strassburg. Virtually all versions of the legend revolve around conflicting themes of romantic love and political loyalty, though no two tellings treat these themes identically.
