Guillaume de Machaut, sometimes spelt Machault (c.1300–1377), was an important mediaeval French poet and composer. Guilllaume de Machaut was "the last great poet who was also a composer," in the words of the scholar Daniel Leech-Wilkinson. Well into the fifteenthth century, Machaut's poetry was greatly admired and imitated by other poets including Geoffrey Chaucer. Machaut is also the most celebrated composer of the 14th century; he composed in a wide range of styles and forms and his output was enormous.
