n. bell which calls worshippers to evening prayer service (Christianity)

Vespers is the evening prayer service in the Roman Catholic, Eastern (Byzantine) Catholic, Eastern Orthodox, and Lutheran liturgies of the canonical hours. The word comes from Latin vesper, meaning "evening." The term is also used in some Protestant (especially Lutheran and Seventh-day Adventist) denominations to describe evening services, and in some Anglican circles is used unofficially to refer to Evening Prayer. [1] [2].
