In this episode, Marion and I talk about our new co-authored book, The Field Armies of the East Roman Empire, 361-630 (Cambridge University Press, 2023). For those interested in the military history of this period, this book contains a downright mutinous revision of the organization of the East Roman field armies and the changing priorities behind their deployments. We also take the opportunity to discuss revisionist scholarship in general, the kinds we like and those we would court-martial.
