The book of hours is a collection of Christian devotional texts that was extremely popular during the late Middle Ages and Renaissance. Each individual copy contains psalms, hymns, readings, and other materials, which were arranged to mirror the monastic cycle of daily prayer and worship. Unlike the various liturgical booksopens a new window that guided communal prayer of monks and priests, the book of hours is a personal prayer book. It was made for those outside the clergy, who nevertheless wished to incorporate certain aspects of Church ritual into their own lives. Individual books of hours were designed to facilitate private prayer and to encourage personal reflection; this was often accomplished through the interplay of text and imagery, as in the example at the top of this page.
Though these books served a spiritual purpose, they were produced commercially and were generally quite expensive. Nevertheless, among those who could afford to pay, they became essential -- even fashionable -- aids to private prayer, and were produced in vast numbers between the 13th and 16th centuries.
Some measure of their popularity must have been due to the fact that books of hours were made largely to suit individual tastes. The language, imagery, script, and even the books' contents were all, at least to some degree, variable. In any given copy, 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 liturgyopens a new window 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 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.
