Gregory the Great was pope from 590 to 604, a time of great turmoil in Italy and in the western Roman Empire generally because of the barbarian invasions. Gregory’s experience as prefect of the city of Rome and as apocrisarius of Pope Pelagius fitted him admirably for the new challenges of the papacy. The Moral Reflections on the Book of Job were first given to the monks who accompanied Gregory to the embassy in Constantinople. This first volume of the work contains books 1–5, accompanied by an introduction by Mark DelCogliano.
