Motets pour la chapelle du Roy, mis en musique, par Monsieur Du Mont abbé de Silly, & maistre de la musique, de ladite chapelle. Basse-continue pour l'orgue.
This is a 1686 Paris book of motets by Henry Du Mont, chaplain-music master to the French royal chapel, printed by Christophe Ballard as a basso continuo part for organ. Its pages are dense black-and-white music notation, each psalm setting opening with a large decorated initial letter whose ornate scrollwork and figures a designer could borrow for display capitals.
