Monastic Hours

If you are interested in seeing how the Divine Office has survived into modern Catholic use (there are, of course, also Anglican monasteries), you can visit this web site. Across the top (or down the left-hand side: it seems to vary by day) are listed the hours currently observed: Matins ("Morning prayer"), Terce, Sext, None, Vespers (Evening), and Compline (Night). The "Office of Readings" has replaced Prime and may be said at any time during the day. The site also offers a brief explanation of the structure of the liturgy. This is a decent hypertext book of hours.

The Divine Office is written in a book (usually several books) called a breviary. The famous medieval books of hours were condensed versions of the Breviary for personal devotional use. Books of hours are some of our richest sources for illuminated manuscripts. This is a good brief introduction to books of hours, and at the same site you can go through several complete books. Wikipedia has some very good illustrations from a range of books, and separate entries on a fair number of specific books (such as the very famous Très Riches Heures of the Duc de Berry).

The Anglican Church has a unique Evensong service, originally a conflation of Vespers and Compline. The BBC offers weekly choral Evensong broadcasts.
