Ambrose of Alexandria (died about 250 AD) was a friend of Origen.
Attracted by Origen's fame as a teacher, he visited his school about 212, and was converted by Origen from the Valentinianheresy to the orthodox faith (Eusebius, Church History, VI. xviii. 1).
He was a sufferer during the persecution under Maximinus Thrax in 235 (Eusebius, Church History, VI. xxviii.), and is last mentioned in Origen's Contra Celsum, which the latter wrote at the solicitation of Ambrose.
He was wealthy and provided his teacher with books for his studies and secretaries to lighten the labor of composition (Eusbius, Church History, VI. xxiii. 1-2; Jerome, De vir. ill., lvi.).
Origen often speaks of him in terms of affection as a man of education and literary and scholarly tastes. All of his works written after 218 are dedicated to Ambrose.

Ambrose of Alexandria, whom he was instrumental in converting from Valentianism to orthodoxy.
At Alexandria Heraclas became head of Origen's school, and shortly afterward, on the death of Demetrius, was consecrated bishop.
Demetrius was Patriarch of Alexandria (189 - 232).
From about this period (212-213) dates Origen's acquaintance with Ambrose of Alexandria, whom he was instrumental in converting from Valentianism to orthodoxy.
A series of attacks on him seems to have emanated from Alexandria, whether for his self-castration (a capital crime in Roman law) or for alleged heterodoxy is unknown; but at all events these fulminations were heeded only at Rome, while Palestine, Phoenicia, Arabia, and Achaia paid no attention to them.
