De Viris Illustribus (Illustrious Men)

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.
