Horologion


The Horologion (Greek: Ὡρολόγιον; Church Slavonic: Часocлoвъ, Chasoslov, Romanian: Ceaslov) or Book of hours provides the fixed portions (Greek: ἀκολουθίαι, akolouthiai) of the Divine Service or the daily cycle of services as used by the Eastern Orthodox and Eastern Catholic churches. Into this fixed framework, numerous moveable parts of the services are inserted.

In its original sense, a horologion (Greek: ὠρολόγιον, "the hour-teller" from hṓra "hour" and -λόγιον -logion, "teller") or Latin was any device or structure for keeping time, such as a sundial or the Tower of the Winds in Athens.

The Horologion is primarily a book for the use of the Reader and Chanters (as distinguished from the Euchologion, which contains the texts used by the Priest and Deacon). Several varieties of Horologia exist, the most complete of which is the Great Horologion (Greek: Ὡρολόγιον τò μέγα, Horologion to mega; Slavonic: Великий Часословъ, Velikij Chasoslov, Romanian: Ceaslovul Mare). It contains the fixed portions of the Daily Office (Vespers, Compline (Great and Small), Midnight Office, Matins, the Little Hours, the Inter-Hours, Typica, Prayers before Meals). The parts for the Reader and Chanters are given in full, the Priest's and Deacon's parts are abbreviated. The Great Horologion will also contain a list of Saints commemorated throughout the year (with their Troparia and Kontakia), selected propers for Sundays, and moveable Feasts (from the Menaion, Triodion and Pentecostarion), and various Canons and other devotional services. The Great Horologion is most commonly used in Greek-speaking churches.
