A Dictionary of Greek and Roman biography and mythology

1. Praefectus Praetorio, apparently in Italy, having Africa also subject to him, near the close of the reign of Constantine the Great, A. D. 336 and 337. The heresiarch Donatus wrote to him a most insolent letter, calling him " the stain of the senate," " the disgrace of the prefects," and similar names; to which abuse Gregory replied "with the patience of a bishop." (Optatus, De Schismate Donatist, 3.3. ed. Dupin; Cod. Theodos. 11. tit. 1. s. 3; 3. tit. 1. s. 2, with the note of Gothofredus ; Gothofred. Prosopog. Cod. Theodos.)
