ACOEMETÆ, or ACOEMETI, in church-history; or, Men who lived without sleep: A set of monks who chanted the divine service night and day in their places of worship. They divided themselves into three Acoluthi bodies, who alternately succeeded one another, so that their churches were never silent. This practice they founded upon the precept, Pray without ceasing. They flourished in the east about the middle of the 6th century. There are a kind of acoemeti still subsisting in the Roman church, viz., the religious of the holy sacrament, who keep up a perpetual adoration, some one or other of them praying before the holy sacrament day and night.
