Sir Perceval of Galles is a Middle English Arthurian verse romance whose protagonist, Sir Perceval (Percival), first appeared in medieval literature in Chrétien de Troyes' final poem, the 12th-century Old French Conte del Graal, well over one hundred years before the composition of this work. Sir Perceval of Galles was probably written in the northeast Midlands of England in the early 14th century, and tells a markedly different story to either Chretien's tale or to Robert de Boron's early 13th-century Perceval. Found in only a single manuscript, and told with a comic liveliness, it omits any mention of a graal or a Grail.
