In Malory's Le Morte d'Arthur, the virgin knight who quests for the Grail. His first appearance in literature is in Perceval, ou le Conte du Graal, written by Chrétien de Troyes c. 1175. In the German version of the story he is called Parzival.
The Welsh model seems to be the historical Peredur and the medieval tale of Peredur, son of Efrawg parallels the Grail tales.
