§ 83. The first meal (_prandium_) took place at mid-day in the frater, soon after sext. During the meal the reader for the week, who had taken his repast before the rest, occupied the pulpit and read from the Bible or some pious book. Grace after meat ended with the _Miserere_, which was sung in procession through the cloister, the concluding collect and suffrages being said in church. The brethren then retired to rest in the dorter, until none. Work of various kinds filled up the time between none and vespers, a service which corresponded in its general structure to lauds. After vespers and the usual grace came supper (_caena_). During the interval between supper and compline (_completorium_), the last office, the convent met in the chapter-house for collation, at which the _Collationes_ of Cassian or a chapter from some other monastic author were read. Compline ended the day, although, in times of lax discipline, there arose a custom of sitting up late in the warming-house which called for correction from episcopal visitors. The strict rule, however, required that the brethren should repair directly after compline to the dorter, and that all doors in the church and cloister should be locked until prime. At Durham the sub-prior went the round of the dorter towards the middle of the night to see that all was in good order. The rule required constant vigilance on the part of the officers, especially with regard to the maintenance of silence and the prevention of the accumulation of private property by the brethren.
