110 Optatus the bishop PL 23, 705
Optatus the African, bishop of Milevis, during the reign of the Emperors Valentinianus and Valens, wrote in behalf of the Catholic party six books against the calumny of the Donatian party, in which he asserts that the crime of the Donatists is falsely charged upon the catholic party.
Optatus Afer, episcopus Milevitanus, ex parte catholica, scripsit Valentiniano et Valente principibus, adversum Donatianae partis calumniam libros sex, in quibus asserit crimen Donatianorum in nos falso retorqueri.
Ὀπτᾶτος, ἐπίσκοπος τῆς Μελιυϊτῶν, τοῦ μέρους τῆς καθολικῆς, ἔγραψε ἐπὶ Βαλεντινιανοῦ καὶ Οὐάλεντος κατὰ τῶν Δονατιανῶν συκοφαντίας λόγους ἓξ, ἐν οἶς λέγει, τὸ ἔγκλημα παρὰ τῶν Δωνατιστῶν εἰς ἡμᾶς ψευδῶς ἐπηνέχθαι.
