My research aims to analyse the transformations of imperial imagery in the period 306-711 AD, by focusing on surviving coins, statues, mosaics, seals, and other representational visual media. Imperial imagery continuously adapted to changing religious, cultural, political, and social conventions. This research studies that adaptation by analysing how Roman classical iconographic traditions and Christian (oriental) iconographic innovations shaped the late Roman and early Byzantine imperial image in the long term. A quantitative analysis of numismatic imagery between 306-711 AD  will reveal how, when, and to what extent imperial numismatic self-representations were transformed. Imperial representations were an important way for Roman and Byzantine emperors to communicate their imperial ideology to different acceptance groups. By analysing the differences between trends in various forms of imperial representations and their intended audiences, this research could reveal to what extent imperial images were adjusted to their specific medium and their target audience. By considering imperial imagery over the long term this research will indicate the fluctuations, long-term breaks, and ‘radical’ changes in imperial iconography. Investigating these changes and the relations between the trends in various imperial representations reveals how the image of emperors gradually changed over time. Simultaneously, important moments of change could be connected with specific political, religious, or economic circumstances.
