Jerome. Lives of Illustrious Men 56
56 Ambrose the deacon PL 23, 667
Ambrosius, at first a Marcionite but afterwards set right by Origen, was deacon in the church, and gloriously distinguished as confessor of the Lord. To him, together with Protoctetus the presbyter, the book of Origen, On martyrdom was written. Aided by his industry, funds, and perseverance, Origen dictated a great number of volumes. He himself, as befits a man of noble nature, was of no mean literary talent, as his letters to Origen indicate. He died moreover, before the death of Origen, and is condemned by many, in that being a man of wealth, he did not at death, remember in his will, his old and needy friend.
897 Ambrosius primum Marcionites, deinde ab Origene correctus, Ecclesiae diaconus, et confessionis Dominicae gloria insignis fuit, cui et Protocteto presbytero liber Origenis de Martyrio scribitur. Hujus industria, et sumptu et instantia adjutus infinita Origenes dictavit volumina. Sed et ipse, quippe ut vir nobilis, non inelegantis ingenii fuit, sicut ejus ad Origenem epistolae indicio sunt. Obiit ante mortem Origenis; et in hoc a plerisque reprehenditur, quod vir locuples amici sui senis et pauperis moriens non recordatus sit.
898 Ἀμβρόσιος πρῶτον Μαρκιωνιστὴς, ὕστερον παρὰ Ὠριγένους διορθωθεὶς, ἐκκλησίας διάκονος, καὶ θείας ἐξομολογήσεως ἐπίσημος ἐγένετο, τούτῳ ὑπὲρ Θεοκτίστου πρεσβυτέρου βίβλος Ὠριγένους περὶ τοῦ Μαρτυρίου γράφεται. Τῇ σπουδῇ τούτου καὶ ἀναλώμασι καὶ ἐπείξει, πρὸς τοῦτον πάμπολλα Ὠριγένης ἐπέστειλε συντάγματα. Ἀλλὰ καὶ αὐτὸς ἀνὴρ εὐγενέστατος ὢν, οὐκ ἄκομψος ἐν τῇ εὐφυΐᾳ ἐγένετο, καθὰ αἱ πρὸς Ὠριγένην τούτου δηλοῦσιν ἐπιστολαί. Ἐτελεύτησε δὲ πρὸς Ὠριγένους· καὶ ἐν τούτῳ παρὰ πολλῶν καταγινώσκεται, ὅτι περ πλούσιος ὢν, τοῦ οἰκείου φίλου γέροντος καὶ πένητος τελευτῶν οὐκ ἐμνήσθη.
