Tristan and Iseult, also known as Tristan and Isolde and other names, is a medieval chivalric romance told in numerous variations since the 12th century. Based on a Celtic legend and possibly other sources, the tale is a tragedy about the illicit love between the Cornish knight Tristan and the Irish princess Iseult. It depicts Tristan's mission to escort Iseult from Ireland to marry his uncle, King Mark of Cornwall. On the journey, Tristan and Iseult ingest a love potion, instigating a forbidden love affair between them.
