Grail Legend

The Grail Legend (also known as the Grail Quest, Quest for the Holy Grail) developed in Europe c. 1050-1485 CE. It most likely originated in Ireland as folklore before appearing in written form sometime before 1056 CE in The Prophetic Ecstasy of the Phantom, an Irish tale. The concept was popularized by the French poet Chretien de Troyes (l. c. 1130-1190 CE) in his Perceval or the Story of the Grail (c. 1190 CE) which he left unfinished and was completed by other poets in the work known as the Four Continuations.
