The book of hours is a collection of Christian devotionalopens a new window texts widely used during the late Middle Ages and Renaissance. Most copies were made for laypeople who wished to incorporate aspects of Church ritual into their own lives. Typical copies therefore contain psalms, readings, and prayers, all arranged to mirror the monastic cycle of daily worship known as the Divine Officeopens a new window. Intended for personal, rather than ceremonial use, individual copies were designed to facilitate quiet prayer and to encourage private reflection; this was often accomplished through the interplay of text and imagery, as in the example at the top of this page.
Though books of hours served a spiritual purpose, they were produced commercially and were generally quite expensive. But among those who could afford to pay, books of hours became essential -- even fashionable -- aids to private prayer and were produced in vast numbers between the 13th and 16th centuries.
Some degree of the book of hours' popularity must have been due to the fact that its contents were highly customizable. The language, imagery, script, and even the contents of books of hours were all, to at least some degree, variable. Copies could be tailored to suit the devotional needs of specific groups of people, or they could be made to please particular individuals. The style and overall quality of decoration might reflect personal preference, local tradition, or simply what a particular buyer could afford to either commission or purchase ready-made. Many books of hours are thus unadorned and modest, while others are conspicuous in their luxury, with the finest examples preserving masterpieces of medieval painting and illumination.
Other differences between books of hours arose from the need to accommodate the diversity of regional worship. Within the medieval church, certain aspects of the liturgy were determined, to at least some degree, by local custom, and individual books of hours were made to reflect these variations. Thus, a book of hours intended for the "use" of Rome will differ from a book of hours made for the use of Paris, or Utrecht, or Sarum (Salisbury). These differences might be reflected in the order and wording of certain prayers or the veneration of local saints or religious events.
Entire cycles of prayer could also be added or excluded based on personal preference, as could a variety of additional texts. These customizations can provide further clues about the origin of specific books of hours and their earliest owners.
Precisely because these books were so frequently personalized, they offer modern readers a kind of window into the varied lives and pious practices of medieval laypersons; as frequent objects of conspicuous consumption sought out by the elite across much of Europe, surviving books of hours also preserve a detailed survey of medieval art and scribal practice.
