Eugenius

Eugenius is known only as a correspondent of Nilus of Ancyra (d. c. 430), the spiritual-advice writer active in the early-5th-century Galatian milieu around Ancyra (modern Ankara). Nilus addresses him most often as "Eugenius the Monk" (and once as "the Prince," princeps, suggesting a magistrate's background), and the five letters consistently treat him as an ascetic under direction: one reproves him sharply for presuming himself perfect though he has not yet completed his fifteenth year of solitary training, while the others counsel him on enduring demonic temptation, drawing on the Psalms to promise divine consolation after affliction. He emerges from these letters as a younger monk being both corrected for spiritual pride and encouraged toward perseverance in the ascetic struggle. He is otherwise unattested.
