Percival , also spelled Perceval, is one of King Arthur's legendary Knights of the Round Table. First made famous by the French author Chretien de Troyes, in the tale Conte du Graal (also known simply as Perceval), his story was allotted to the fictional figure of Peredur son of Efwc in the Welsh adaptation of Chretien's tale called Peredur ab Efrawc. He is most well known for being the original hero in the quest for the Grail before being replaced in later literature by Galahad.
