A conversation with Efi Ragia (Hellenic Open University) on coming to grips with social class in Byzantium, a society without a fixed social hierarchy, at least not fixed in terms of hereditary groups. Claims to high (or low) social standing were often rhetorical and fluid. Who were "the powerful"? By what criteria could they be recognized, and how might others aspire to that position? The conversation is based on her article ‘Social Group Profiles in Byzantium: Some Considerations on Byzantine Perceptions about Social Class Distinctions,’ Byzantina Symmeikta 26 (2016) 309-372.
