Jerome. Lives of Illustrious Men 55
55 Ammonius PL 23, 667
Ammonius, a talented man of great philosophical learning, was distinguished at Alexandria, at the same time. Among many and distinguished monuments of his genius, is the elaborate work which he composed On the harmony of Moses and Jesus, and the Gospel canons, which he worked out, and which Eusebius of Cæsarea, afterwards followed. Porphyry falsely accused him of having become a heathen again, after being a Christian, but it is certain that he continued a Christian until the very end of his life.
Ammonius, vir disertus et valde eruditus in philosophia, eodem tempore Alexandriae clarus habitus est: qui inter multa ingenii sui et praeclara monumenta etiam de consonantia Moysi et Jesu elegans opus composuit, et evangelicos canones excogitavit, quos postea secutus est Eusebius Caesariensis. Hunc falso accusat Porphyrius, quod ex Christiano Ethnicus fuerit, cum constet eum usque ad extremam vitam Christianum perseverasse.
Ἀμμώνιος ὁ ἐλλογιμώτατος καὶ φιλοσοφίας πεπαιδευμένος, ἐν τοῖς αὐτοῖς χρόνοις ἐν Ἀλεξανδρείᾳ λαμπρὸς φανεὶς, μεταξὺ τῶν συνταγέντων παρ' αὐτοῦ περιφανῶν λόγων, καὶ περὶ τῆς συμφωνίας Μωϋσέως καὶ Ἰησοῦ βίβλον θαυμαστὴν συνέθηκε, καὶ εὐαγγελικοὺς κανόνας ἐφεῦρεν, οὗς μετὰ ταῦτα ἐξηκολούθησεν Εὐσέβιος ὁ Καισαρεύς. Τούτου πλαστῶς κατηγορεῖ ὁ Πορφύριος, φάσκων ἀπὸ Χριστιανῶν ἐθνικὸν γεγενῆσθαι, ὅστις ἄχρι τῆς τελευταίας Χριστιανὸς διετέλεσεν.
