Breviarium Monasticum

The Breviarium Monasticum is a comprehensive book used by monks and religious communities to guide their daily prayers and liturgical practices. It contains the structure, texts, and instructions for reciting the Divine Office, which is the series of prayers said at specific times throughout the day. Historically, it helped ensure uniformity and devotion within monastic life, often including psalms, hymns, readings, and other prayer elements. Essentially, it's a detailed prayer manual that structured the spiritual routines of monastic communities, fostering discipline, reflection, and communal worship.
