Se’atat, the Horologium
There are two types of Horologium, for the day and for the night. The Horologium was composed by distinguished 15th century scholar, Abba Giyorgis of Gascha; during the ensuing it was gradually enriched by additional hymns and prayers. In big churches it is usual for monks, priests and deacons to conduct the Se’atat in the northern part of the ambulatory, while the Debteras are conducting a different service.



The book of Se’atat contains the great public prayers of the Church, not necessarily said in public but always offered in the name of the church. It is recited at stated hours in churches, monasteries and outside. It is divided into seven parts known as canonical hours and each part is recited at its own hour. These hours are known as Night, Prime, Terce, Sext, None, Vespers, and compline. To be more exact the first of the canonical hours is night or matins (morning office) which is followed by lauds or praises of God. These are reckoned as one “hour”. The next division is prime or first because it is said at “first hour” or sun rise. Then terce or third, recited at the third hour. Sext or sixth at noon; none or ninth at three O’clock; Vespers is next, signifying evening services, and then comes compline or the completion.



The office contains psalms, discourses by the great fathers of the church, hymns and prayers. This office is an abundant treasure of grace. Deacons stand for the “gibre leilit” or night service and chant the “Se’atat” or Book of hours, serving till dawn. There was an arrangement under which a debtera held some church land and was bound in return to recite the Se’atat or Hours of the night at certain times, or held land for which he was bound to recite the “Hours of the Day” in the church. But the recital of the office is not obligatorily imposed on priests and deacons.
