ABSTRACT
More than any earlier Eastern-based emperors, Theodosius I had concentrated imperial power, government, military authority, and finally religious jurisdiction (except for the Bishop of Rome) in the single capital of Constantinople. Power all flowed from that city, as it had once flowed from Rome. For many years the official symbols, on coins and effigies, continued to proclaim the twin centres of the Roman empire, the twin guardian spirits of Rome and Constantinople. In the political reality of the fifth century, there was now only one. 1
