^{page 21 note 2} Credo en musique: in 1465, the Credo was among the pieces singled out, according to ancient statute, to be sung in polyphony or improvised descant on special occasions. See Archives Nationales, LL. 253, 71^v. In vernacular texts of the sixteenth-century, polyphony is referred to as ‘choses faictes’ or ‘musique faite’ or simply as ‘musique’.

^{page 21 note 3} ‘Le Patrem’, from the first word sung at the entry of the choir, is a usual term for the Creed. The Celebrant sang the words of the intonation ‘Credo in unum Deum’, to the plainsong note in his Missal. The choir replied in polyphony with the phrase ‘Patrem omnipotentem factorem caeli et terrae’.
