In the morning having said Matins, they went to the church (for Mass)..
Matins and Lauds (about 7.30 A.M.); Prime, Terce (High Mass), Sext, and None (about 10 A.M.); Vespers and Compline (4 P.M.); and from four to eight hours (depending on the amount of music and the number of high masses) are thus spent in choir.
In the Church of England since the Reformation matins is used for the order of public morning prayer.
Between the lessons the ass was solemnly fed, and at the conclusion of the service was led by the precentor out into the square before the church (conductus ad ludos); water was poured on the precentor's head, and the ass became the centre of burlesque ceremonies, dancing and buffoonery being carried on far into the night, while the clergy and the serious-minded retired to matins and bed.
Since the 6th century the number and order of the hours have been fixed thus: matins, lauds, prime, terce, sext, none, vespers, compline.
