Silvanus was formerly a rhetorician, and had been brought up in the school of Troïlus the sophist; but aiming at perfection in his Christian course, he entered on the ascetic mode of life, and set aside the rhetorician's pallium. Atticus bishop of Constantinople having taken notice of him afterwards ordained him bishop of Philippopolis.
