This is a lively and fiarly comprehensive survey of the Roman empire from Augustus to Marcus Aurelius. The chapters alternate between "big man" history (based on periods: Augustan, the resto f the Julio-Claudians, Galba thru Trajan, Hadrian thru Marcus Aurelius) and more general social history. This is a great structure and it allows the author to reinforce major developments by mentioning them in both chapters. There is a short survey of the emperors who followed Marcus Aurelius as a sort of epilogue, but there is not corresponding chapter on the social history of this period.
Wells offers the reader a massive amount of data, and it is probably impossible to take it all in on the first read. This book covers major dates, figures, and developments in architecture, law, and governance. It may come off as a little dry to those not already interested in this period. If you are not a historian, you may want to start with a popular biography of an emperor or two to get yourself familiar with the basics. I intend to use this a reference work for my own teaching, but I'm not sure if I would assign it to students. There may be a more accessible text for Roman Imperial history out there.
