Two of the most influential Latin authors from the turn of the fifth century, Augustine and Jerome, are known for such enduring works as Confessions, City of God, and the ‘Vulgate’ translation of the Christian Scriptures. Their correspondence has been described as ‘one of the most revealing, dramatic, and exhilarating portraits’ of the two men (R. J. O’Connell). In reading their letters, we will touch on many points of historical, literary, and theological interest: the practice of letter-writing in the ancient world, the use of allusions to classical sources, the demands of church administration and monastic life, and the arguments employed in biblical exegesis. At the same time, we will see, with more than usual clarity, the character and attitudes of Augustine and Jerome themselves.
