Manuale rituum ecclesiasticorum ad usum ecclesiae et dioecesis Bajocensis. Authoritate reverendissimi in Christo Patris, ac DD. Francisci de Nesmond, episcopi Bajocensis, recognitum.
A 1687 Catholic ritual manual printed in Caen by Jean Poisson for the diocese of Bayeux, issued under Bishop François de Nesmond. Its pictures are close-up pages of square-note plainchant set on four-line staves, with Latin antiphon and psalm text in black letter below each staff. A designer might take the strong black note heads, bold staff rules and dense even texture as a model for austere historical typography and sacred music notation.
