Tristan, a Knight of the Round Table in Arthurian legend, who seems to be best remembered as the lover of Esyllt (Tristan and Iseult). But the earliest texts hint at a character who was far more than just a lover; he was a master of deception and had the ability to shape-shift, a definite attribute of a trickster. In the Cymric Trioedd, Esyllt is his uncle's wife; with the help of the swineherd, Drystan arranges for a secret tryst with her, but Arthur shows up unexpectedly wanting to steal some of his uncle's swine, and Drystan somehow outwits the Forever King. As for the etymology of the name, most sources try to associate it with Latin tristis "sad," referring to the tragic fate of the young "lover." Some try to link it with Pictish drust of unknown meaning, or Celtic drest, "riot, tumult." The latter probably comes closest to fitting his true character; compare with Old English þríst/þríste: "bold, daring, rash, audacious," and even "shameless."
