Early Byzantine civilization was a mixture of many different cultural contributions. It was made up of three, main elements, however: its new religion, Christianity; the legacy of ancient Greek thought; and the Roman administrative tradition. The combination of these elements was the rich and wide-ranging intellectual and cultural life of Early Byzantium, which provided the foundations for the intellectual achievements of the following centuries. Scientific achievements, intense theological debates, developments in the law and a rich literary and artistic output are all presented in the web pages that follow.
