The Holy Grail by Sir Thomas Malory from the Caxton Edition of the Morte D'Arthur

According to Wikipedia: "Sir Thomas Malory (c. 1405 - 14 March 1471) was an English writer, the author or compiler of Le Morte d'Arthur. The antiquary John Leland (1506-1552) believed him to be Welsh, but most modern scholars, beginning with G.L. Kittridge in 1894, assume that he was Sir Thomas Malory of Newbold Revel in Warwickshire, who was a knight, land-owner and Member of Parliament. The surname appears in various spellings, including Maillorie, Mallory, Mallery, and Maleore. The name comes from the Old French adjective maleüré (from Latin male auguratus) meaning ill-omened or unfortunate."
