This book presents a new history of the leadership, organization, and
disposition of the field armies of the east Roman empire between Julian
(361-363) and Herakleios (610-641). To date, scholars studying this
topic have privileged a poorly understood document, the Notitia
dignitatum, and imposed it on the entire period from 395 to 630. This
study, by contrast, gathers all of the available narrative, legal,
papyrological, and epigraphic evidence to demonstrate empirically that
the Notitia system emerged only in the 440s and that it was already
mutating by the late fifth century before being fundamentally reformed
during Justinian's wars of reconquest. This realization calls for a new,
revised history of the eastern armies. Every facet of military policy
must be reassessed, often with broad implications for the period. The
volume provides a new military narrative for the period 361-630 and
appendices revising the prosopography of high-ranking generals and
arguing for a later Notitia.
