English author of the prose romance Le Morte d'Arthur about 1470. It is a translation from French, modified by material from other sources, and deals with the exploits of King Arthur's knights of the Round Table and the quest for the Grail. Malory's identity is uncertain. He is thought to have been the Warwickshire landowner of that name who was a member of Parliament for Warwick in 1445 and in 1451 and 1452 was charged with rape, theft, and attempted murder. If that is so, he must have compiled Morte d'Arthur during his 20 years in Newgate prison.
