Percival (/ˈpɜːrsᵻvəl/) (also spelled Perceval, Percivale, and other variants) 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.
Chrétien de Troyes wrote the first story of Perceval, le Conte du Graal. Wolfram von Eschenbach's Parzival, Sir Thomas Malory's Le Morte d'Arthur, and the now lost Perceval of Robert de Boron are other famous accounts of his adventures.
There are many versions of Perceval's birth. In Robert de Boron's account Saint Graal, he is of noble birth; his father is stated to be either Alain le Gros, King Pellinore or another worthy knight. His mother is usually unnamed but plays a significant role in the stories. His sister is the bearer of the Holy Grail; she is sometimes named Dindrane. In tales where he is Pellinore's son, his brothers are Sir Aglovale, Sir Lamorak and Sir Dornar, and by his father's affair with a peasant woman, he also has a half-brother named Sir Tor.
