Magister Franciscus (fl. 1370–80) was a French composer-poet in the ars nova style of late medieval music. He is known for two surviving works, the three-part ballades: De Narcissus and Phiton, Phiton, beste tres venimeuse; the former was widely distributed in his lifetime.[1] Modern scholarship disagrees on whether Franciscus was the same person as the composer F. Andrieu.
