Bema

BEMA: In classical literature a semicircular platform at the end of a basilica, which supported the official seat of the judge. When the basilican style was adapted to Christian use (see Architecture, Ecclesiastical), the apse, or similar semicircular termination of the building, was reserved for the seats of the bishop and clergy, and the same name was sometimes applied to it. In a more restricted sense it signifies any elevated place in the church, such as that from which the gospel was read, and is thus synonymous with ambo.
