The Ecclesiastical History of Socrates Scholasticus

During this period upon the death of Flavian Porphyry received the episcopate of Antioch, and after him Alexander was set over that church. But at Rome, Damasus having held that bishopric eighteen years Siricius succeeded him; and Siricius having presided there fifteen years, Anastasius held sway over the church for three years; after Anastasius Innocent [was promoted to the same see]. He was the first persecutor of the Novatians at Rome, and many of their churches he took away.
