His date and place of birth are unknown.
He was the syncellus (cell-mate, the confidential campanion assigned to the patriarchs, sometimes little more than a spy) or private secretary of Tarasius, patriarch of Constantinople (784-806), after whose death he retired to a convent, and wrote his Chronicle of events from Adam to Diocletian (285).
At his earnest request, the work, which he doubtless intended to bring down to his own times, was continued after his death by his friend Theophanes Confessor. The Chronicle, which, as its title implies, is rather a chronological table (with notes) than a history, is written with special reference to pre- Christian times and the introduction of Christianity, and exhibits the author as a staunch upholder of orthodoxy. But in spite of its religious bias and dry and uninteresting character, the fragments of ancient writers and apocryphal books preserved in it render it specially valuable. For instance, considerable portions of the original text of the Chronicle of Eusebius have been restored by the aid of Syncellus.
George reveals himself as a staunch upholder of orthodoxy, and quotes Greek Fathers such as Gregory Nazianzen and John Chrysostom.
