The Ecclesiastical History of Socrates Scholasticus

But Arsacius did not long survive his accession to the bishopric; for he died on the 11th of November under the following consulate, which was Stilicho’s second, and the first of Anthemius. In consequence of the fact that the bishopric became desirable and many aspired to the vacant see, much time elapsed before the election of a successor: but at length in the following consulate, which was the sixth of Arcadius, and the first of Probus, a devout man named Atticus was promoted to the episcopate. He was a native of Sebastia in Armenia, and had followed an ascetic life from an early age: moreover in addition to a moderate share of learning, he possessed a large amount of natural prudence. But I shall speak of him more particularly a little later.
