George Syncellus was a Byzantine chronicler and ecclesiastic. He had lived many years in Palestine as a monk, before coming to Constantinople, where he was appointed synkellos to Tarasius, patriarch of Constantinople. He later retired to a monastery to write what was intended to be his great work, a chronicle of world history, Ekloge chronographias, or Extract of Chronography. According to Anastasius Bibliothecarius, George "struggled valiantly against heresy [i.e. Iconoclasm] and received many punishments from the rulers who raged against the rites of the Church", although the accuracy of the claim is suspect.
