Le Morte d'Arthur (originally spelled Le Morte Darthur, Middle French for "the death of Arthur") is a compilation by Sir Thomas Malory of Romance tales about the legendary King Arthur, Guinevere, Lancelot, and the Knights of the Round Table. The book interprets existing French and English stories about these figures, with some of Malory's own original material.

Le Morte d'Arthur, the well-known English-language account of the Arthurian legend, was written by Sir Thomas Malory. Malory's personal narrative is mostly unknown, but the fact that he called himself a "knight prisoner" suggests that he was either a criminal or a prisoner of war. Although his identity has never been verified, the majority of researchers agree that he was a Warwickshire native who was imprisoned on several occasions during the Wars of the Roses The prayers that may be found in the Winchester Manuscript of Le Morte d'Arthur provide the majority of the information we have about Thomas Malory. He is distinguished from the other applicants for the position by being called a "knyght prisoner." Grammatically speaking, references to Malory as a knight may be found in the third and last volume of the Manuscript. It's unlikely that Queen Elizabeth II bestowed a knighthood on Le Morte d'Arthur's author.
