An illustration for May from a Flemish Book of Hours, by Simon Bening in the early 16th century

The Metropolitan Museum has three copies of the Book of Hours at the Cloisters: the Hours of Jeanne d’Evreux, the Belles Heures of Jean de France, duc de Berry, and a diminutive manuscript by Simon Bening.

The devotion was modeled after the Divine Office, which was recited in monasteries at specific hours of the day. There were eight sets of prayers in the Book of Hours, meant to be said over a 24-hour span of time.

Some books also had other elements, such as a set of gospel lessons, the psalms, and prayers to saints known as Suffrages, according to the Met. Calendars reminded patrons of important feasts and saints’ days.

The Arrest of Christ and the Annunciation, The Hours of Jeanne d'Evreux

"The Hours of Jeanne d’Evreux was made for a fourteenth-century queen of France, and diminutive size, gossamer-thin parchment, and delicate painting by Jean Pucelle all contribute to its exquisite femininity. It includes a Life of Saint Louis, the king of France who was great-grandfather of Jeanne d’Evreux (54.1.2, fols. 154v–155r). Each of the Hours of the Virgin is introduced not only with the traditional scenes from Jesus’ infancy, but also a dramatic scene from the final days of his life, known as the Passion, on the facing page (54.1.2, fols. 82v–83r). All are rendered in grisaille, black and white drawings with lightly tinted backgrounds and other areas." (Metropolitan Museum of Art)
