Book of hours produced in England, probably London, perhaps for a member of a religious confraternity or community. Includes calendar, Office of the Virgin (use of Sarum), Seven Penitential Psalms and incipits of the Gradual Psalms, litany, notated Office of the Dead (use of Sarum), and a variety of prayers. The musical notation in the Office of the Dead is unusual, as is the absence of the prayers Obsecro te and O intemerata. Evidence of use includes erasure of Thomas à Becket from calendar, erasures in text, and 17th-century additions in English to calendar.
