The work concerns the social structure and social relationships in the sixth-century writings of Procopius of Caesarea. It aims to not only shed light on the changes and continuities in Roman society and social relationships of the sixth century, it also aims to establish the reliability and accuracy of Procopius with regard as an author. This is accomplished by examining a number of groups within Roman society and the roles they play in his works such as the political elite, non-Romans, religious communities, and others and then establishing Procopius’ reliability by a comparative analysis with other contemporary sources-literary, archaeological and epigraphic.
