The first full-scale translation and commentary on Eutropius, whose "Breviarium" (Abbreviated History of Rome) was a major vehicle for transmitting knowledge of Roman history to people of the Middle Ages and beyond.

This is a full-scale translation and commentary in English of Aurelius Victor's De Caesaribus, which provides a brief survey of the emperors of Rome from Octavian Augustus in 30 BC to Constantius II in AD 360. The book comprises an introduction, translation and full historical/historiographical commentary, and contains maps, a select bibliography and an index.
