In pagan Rome, the antistes is the leader of rites and administrator of a temple, the priest or high priest, though not as a specialist term in sacred language, despite its rare inscriptional use (CIL III 1115,7. X 5654). As old Roman temples did not have permanent priests, the expression was used for specific sacral colleagues such as the vestals (Liv. 1,20,2) or the Decemviri as A. of Apollo (Liv. 10,8,2), for foreign (peregrine) gods like Ceres with a fixed priesthood, or for cults outside Rome (Cic. Verr. 2,3,111).
