Arator a subdeacon of the Roman Church in the time of pope Vigilius, was a native of Liguria. In A.D. 526 he gained reputation as an advocate in a mission to Theodoric the Ostrogoth on behalf of the Dalmatians; in consequence of which he was made private secretary and intendant of finance to Athalaric, his successor. He subsequently left court, received ordination, and was elected subdeacon A.D. 541. He wrote Historia Apostolica ex Luca Expressa, in Latin verse, which, with other poetry, he dedicated to Vigilius (ed. princeps, Milan, 1469, 8vo).
