Jerome. Lives of Illustrious Men 90
90 Theodorus the bishop PL 23, 695
Theodorus, bishop of Heraclea in Thrace, published in the reign of the emperor Constantius commentaries On Matthew and John, On the Epistles and On the Psalter. These are written in a polished and clear style and show an excellent historical sense.
, Heracliae Thraciarum episcopus, elegantis apertique sermonis, et magis historicae intelligentiae, edidit sub Constantio principe commentarios in Matthaeum, et in Joannem, et in Apostolum, et in Psalterium.
Θεόδωρος, Ἡρακλείας τῆς Θρᾳκῶν ἐπίσκοπος, εὐφυοῦς καὶ ἀρίστου λόγου καί ἱστορικῆς διανοίας, ἐξέδωκεν ἐπὶ Κωνσταντίου βασιλέως ὑπομνήματα εἰς Ματθαῖον καὶ Ἰωάννην, καὶ εἰς τὸν Ἀπόστολον, καὶ εἰς τὸ Ψαλτήριον.
