Introduction
Lists of important Roman historians usually include cerebral Polybius, the friendly court historian Titus Livius, the austere Tacitus, and the gossipy Suetonius. To one extent or another, all of them were participant observers—actors as well as recorders of Roman life and politics.
Rarely added to this pantheon is Cassius Dio. Born in the mid-second century, Dio was Greek by birth but Roman by office. As a senator during one of the most tumultuous periods of the Empire, he witnessed upheaval firsthand. His massive Roman History spans from Rome’s legendary beginnings to his own day, making him our only source for many events. But should we think of him as merely a Tacitus imitator, or as an important historian in his own right?
With me to talk about Cassius Dio is Colin Elliott, Professor of History at Indiana University and host of the Pax Romana Podcast.
