Gareth

Sir Gareth [ˈɡarɛθ] (Old French: Guerrehet) was a Knight of the Round Table in Arthurian legend. He is nicknamed "Beaumains" in Sir Thomas Malory's Le Morte d'Arthur. He was the youngest son of Lot and of Morgause, King Arthur's half-sister, thus making him Arthur's nephew, as well as brother to Gawain, Agravain, Gaheris, and half-brother to Mordred.

Sir Gareth is mentioned in Chrétien de Troyes's Perceval, the Story of the Grail. Several of Sir Gareth's adventures are narrated in the Lancelot-Grail cycle, and his death at the hands of Sir Bors (during Lancelot's rescue of the queen from being burned at the stake) is related in the Death of Arthur, the final volume of the cycle. (The Lancelot and the Death of Arthur sections of the Lancelot-Grail cycle differ in their characterization of Gareth: in the Lancelot, he is portrayed as Gawain's most cherished brother; in the Death of Arthur, his older brother Gaheris is represented as the most cherished.) He is the subject of Book VII in Sir Thomas Malory's Le Morte d'Arthur, which tells how he became a knight.
