Le Morte d'Arthur (originally spelled Le Morte Darthur, Middle French for "the death of Arthur") is a reworking of traditional tales by Sir Thomas Malory about the legendary King Arthur, Guinevere, Lancelot, Merlin and the Knights of the Round Table. Malory interprets existing French and English stories about these figures and adds original material (e.g., the Gareth story).
Le Morte d'Arthur was first published in 1485 by William Caxton, and is today perhaps the best-known work of Arthurian literature in English.
