Ceremonial de l'election des papes : dressé par le commandement du Pape Gregoire XV, traduit en françois. Et le Traité de l'election des papes
A 1655 Paris printing by Antoine de Sommaville of a French translation of Pope Gregory XV's ceremonial for papal elections, with a treatise on the subject by Jérôme Bignon, intended for readers interested in church governance and ecclesiastical ritual. The pictures are a large decorated initial D with foliage, a historiated initial showing armed men and a kneeling figure in woodcut, and a plain capitals heading for Bulla Pii Papae IV, all set in black-letter and roman type with a light paper texture that suggests early modern printing.
