Malory scholar Eugène Vinaver famously argued that the book often called "Le Morte Darthur" is more properly understood to be a collection of eight romances. The eight romances, according to Vinaver, are The Book of Arthur, the Book of Arthur and Lucius Emperor of Rome, the Book of Launcelot, the Book of Gareth, the Book of Tristram, the Book of the Sankgreal, the Book of Launcelot and Guinevere, and the Death of Arthur. For centuries the oldest copy of Malory anyone knew was the print edition, edited and printed by early English publisher William Caxton. Then an assistant master named Walter Oakeshott found a manuscript (that is, hand-written by scribes) in the Winchester library. Vinaver based his theory of eight romances on the fact that the Winchester manuscript was different from Caxton's edition, and especially is organized differently, plausibly like it's eight separate romances in one volume.
