ACACIUS, surnamed Luscus, because he was blind of one eye, was bishop of Cæsarea in Palestine, and succeeded the famous Eusebius: he had a great share in the banishment of Pope Liberius, and bringing Felix to the see of Rome. He gave name to a sect, and died about the year 365. He wrote the life of Eusebius, which is lost, and several other works.
