Philippe de Vitry

Philippe de Vitry was a French composer-poet, bishop and music theorist in the ars nova style of late medieval music. An accomplished, innovative, and influential composer, he was widely acknowledged as a leading musician of his day; the early Renaissance scholar Petrarch wrote a glowing tribute, calling him: "... the keenest and most ardent seeker of truth, so great a philosopher of our age." The important music treatise Ars nova notandi (1322) is usually attributed to Vitry.
