George Synkellos, a monk of Constantinople who once held a position of authority under the patriarch Tarasios, composed (in Greek) a chronicle of universal history in the early ninth century. Beginning with the creation of the universe, the chronicle preserves a rich collection of ancient sources, many of them otherwise unknown. The English translation provided here, together with introduction and notes, promises to make this influential and wide-ranging history more accessible to Byzantinists, students of ancient historiography, and specialists in biblical chronology, early Judaism, Egypt, and the Ancient Near East.
