Jerome. Lives of Illustrious Men 32
32 Modestus PL 23, 647
Modestus also in the reign of Marcus Antoninus and Lucius Aurelius Commodus wrote a book Against Marcion which is still extant. Some other compositions pass under his name but are regarded by scholars as spurious.
Modestus et ipse sub imperatore M. Antonino, et L. Aurelio Commodo, adversum Marcionem scripsit librum, qui usque hodie perseverat. Feruntur sub nomine ejus et alia syntagmata, sed ab eruditis quasi ψευδόγραφα repudiantur.
Μοδεστὸς, καὶ αὐτὸς ἐπὶ Ἀντωνίνου καὶ Κομόδου κατὰ Μαρκίωνος συνέταξε βίβλον, ἤτις ἄχρι σήμερον ὑπάρχει. Φέρεται καὶ ἄλλα αὐτοῦ συγγράμματα, ἅτινα παρὰ τῶν πεπαιδευμένων ψευδεπίγραφα ἀποδοκιμάζεται.
