 As Chapter 66 of his On the Reckoning of Time, in 725 Bede wrote the Greater Chronicle (chronica maiora), which sometimes circulated as a separate work. For recent events the Chronicle, like his Ecclesiastical History, relied upon Gildas, upon a version of the Liber pontificalis current at least to the papacy of Pope Sergius I (687 – 701), and other sources. For earlier events he drew on Eusebius's Chronikoi Kanones. The dating of events in the Chronicle is inconsistent with his other works, using the era of creation, the anno mundi.
