Breviary of Alaric was created in 506.

He started reading the daily prayers in his breviary early in the morning.

A book containing the prayer service for each day.

The most famous prayer that is linked to St. Benedict is the Breviary, the monastic Breviary. The Rule of St. Benedict is not very long, but a HUGE portion of it is taking up with instructions on celebrating the Divine Office. Up until the revisions of Vatican Council II, this was in a four volume work known as the ''Monastic Breviary''.

The word "breviary" comes from brevis. This means concise or short. It's a liturgical book of the Latin liturgical rites of the Catholic Church. This book contains prayers, readings, Psalms, notations and hymns.
