Book of Hours, Use of Mons, Philadelphia, Free Library of Philadelphia, Lewis E 89, fol. 1r (beginning of the Hours of the Virgin)
The “Use” in a Book of Hours generally refers to the specific, regional variants found in the central devotional text, the Hours of the Virgin. Because these variants are often specific to a city or region in Europe, determining the “Use” of a Book of Hours can, at least in theory, help us determine where the book was intended to be read and prayed from. This can be helpful information indeed when faced with a Book of Hours that otherwise has no ownership or localization information! Use can be determined by comparing the Antiphon and Chapter readings for two of the Hours of the Virgin–Prime and None–to lists established by scholars on the basis of firmly-situated manuscript Books of Hours or early printed editions, most actually printed in Paris, that nonetheless state explicitly for which town they were meant to be used.
