Recent years have seen a remarkable revival of research on Cassius Dio and his Roman History, including the publication of numerous volumes of collective essays, and this has been accompanied by a much higher estimation of his achievement than used to be customary. This article seeks to assess the progress made on a range of key issues relating to Dio and his history and to point ahead to further directions for research. The chief topics considered are Dio’s career as senator and historian, central aspects of his history (transmission, sources and models, structure, speeches), and Dio’s handling of politics and system change.
