Inge Mennen, Ph.D. (2010) in History, Radboud University Nijmegen, is currently Lecturer in Ancient History at the University of Amsterdam. She has published on the Severan emperors’ representation of power, and the role of senators and high equestrians in imperial administration.

"Mennen's study of the changing power and status relation between the highest level of Roman imperial administration is a well written analysis of a highly complex and methodologically challenging period, and offers a clear and coherent contribution to scholarship. Mennen draws on the available evidence and treats both the literary and epigraphic records with great care. All in all Mennen's study will be of great interest to those in the field of 3rd century imperial administration and of the period in general." Jesper Majbom Madsen in BMCR, 25.04.2012
