(Greek: sequence)
The arrangement of the Divine Office in the Greek Church, beginning with Little Vespers before sunset and Greater Vespers after it; the Orthros (Greed: dawn), in two parts, corresponding to Matins and Lauds of the Roman Rite, is said at midnight; little Hours are said during the day and the Office closes with the Apodeipnon (Greek: after-supper service) as the Roman does with Complin.
