DESCRIPTION:
Tristan and Isolde is a tale made popular during the 12th century through Anglo-Norman literature, inspired by Celtic legend, particularly the stories of Deirdre and Naoise and Diarmuid Ua Duibhne and Gráinne. It has become an influential romance and tragedy, retold in numerous sources with many variations. The tragic story is of the adulterous love between the Cornish knight Tristan (Tristram) and the Irish princess Iseult (Isolde, Yseult, etc.). The narrative predates and most likely influenced the romance of Lancelot and Guinevere in the Matter of Britain and has had a substantial impact on Western art, the idea of romantic love, and Western literature since it first appeared in the 12th century. While the details of the story differ from one author to another, the overall plot structure remains much the same.

"Chevrefoil" is a Breton lai by the medieval poet Marie de France. The eleventh poem in the collection called The Lais of Marie de France, its subject is an episode from the romance of Tristan and Iseult.
