Semnium (Σεμνεῖον,, a temple), a name given by Philo to places of worship of the Therapeutae (q. i.). He says, "In every one of their dwellings there is a sacred house or chapel, which they call their semnium, or monastery, where they perform the religious mysteries proper to their holy lives" (Bingham, Christ. Antiq. vol. 7, ch. 2, § 11). Monasteries came afterwards to be called semnia, as Suicerus shows out of Balzamon, Methodius, and Suidas. See Bingham, Christ. Antiq. vol. 7, ch. 2, § 14.
