Abstract

Abstract The Sasanians have been characterized as Rome’s enemy par excellence in the ancient sources as well as in modern scholarship. According to the Greek and Roman historians, from the moment of its emergence in the second decade of the third century CE, the new dynasty pursued an extremely aggressive policy towards the Western neighbour that resulted in fierce and renewed military conflict and brought the Roman Empire to the brink of desaster. However, a closer look on the respective historiographic and biographic texts from contemporary and later authors reveals a deeper meaning behind their depictions of Roman-Sasanian conflict in the third century. This article argues that authors like Cassius Dio, Herodian and the composer of the fourth-century Historia Augusta used these narrations in order to name and address severe problems within the Roman Empire. Their considerations focused on the mechanisms of imperial government and self-representation which underwent a profound and radical change in the course of the third century. The principate of the previous centuries with its perfectly balanced system of communication between the emperor, the senate, the people of Rome and the army was gradually transformed into an overt military monarchy in which the emperors ostentatiously displayed their exclusive reliance on the soldiers as the crucial foundation of their rule. Although the characterization of Sasanian politics and attitudes towards Rome in the historiographic and biographic texts was certainly not merely an interpretatio Romana, the conditions within the Roman empire have to be taken into account in order to fully understand the contemporary and later historians’ intentions and the specific thrust of their texts.
