This is an early ninth- century text swiftly covering history from Creation to 284 CE. The chronicle is called Ekloge Chronographias (Extract of Chronography) in one of the main manuscripts. The title of this text attributes it to “George, monk and s ynkellos when Tarasios was Patriarch.” While the introduction states that the author intended to cover the period from Creation to the year 6300 (808 CE), the text ends in 284 CE. In another passage, the year 6302 (810 CE) is noted as the “current year.” The preface to the Chronicle of Theophanes explains that it is a continuation of George's work. How much of Theophanes's chronicle was based on material prepared by George is a matter of debate.

The text works to reconcile various systems of dating history and synchronize events from biblical history with ancient Mediterranean histories. It begins with an analysis and critique of previous chronographers, especially Julius Africanus and Eusebius. Whereas Africanus preferred a symbolic chronology (big round numbers in accordance with a prophetic view of history) without caring about non- Christian (Babylonian, Egyptian, etc.) traditions of history, and Eusebius worked to harmonize those traditions with biblical history – even when this meant admitting difficulties with biblical chronology – George's text tried to create a harmonized universal history that proved the veracity of the biblical account at all times. Torgerson characterizes it as an investigation into the “relationship between a timeless God and a time- bound Creation.”

The first quarter of the chronicle deals with the great complexities of reckoning time before Abraham. The text is concerned with working out discrepancies between the Septuagint and various Hebrew versions of scripture. It lists biblical events under the “universal years” since Creation, but the names of kings and events from Egyptian, Babylonian, Greek and Latin history are interspersed, listed under their own headings. Things that do not fit neatly into any of the relevant headings are reported in a “miscellany” at the end of the section, after which it moves on to the next set of “universal years.” It also frequently includes quotations from other historians and chroniclers that are pertinent to the period under discussion.
