Le Mort d'Arthur / Le Morte Darthur (in two volumes)

Le Morte d'Arthur (spelled Le Morte Darthur in the first printing and also in some modern editions, Middle French for la mort d'Arthur, "the death of Arthur") is Sir Thomas Malory's compilation of some French and English Arthurian romances. The book contains some of Malory's own original material (the Gareth story) and retells the older stories in light of Malory's own views and interpretations. First published in 1485 by William Caxton, Le Morte d'Arthur is perhaps the best-known work of English-language Arthurian literature today. Many modern Arthurian writers have used Malory as their source, including T. H. White for his popular The Once and Future King.
