The Venerable Bede
Bede (672/673 - 735) was an Anglo-Saxon theologian, historian, chronologist and monk at the monastery of St. Peter and its companion monastery of St. Paul in the Kingdom of Northumbria of the Angles. The five-volume "Historia ecclesiastica gentis Anglorum" (Ecclesiastical History of the English People), completed in about 731 CE, is a history of the Christian Churches in England, and of England generally. It focusses on the conflict between the pre-Schism Roman Rite and Celtic Christianity. It is considered one of the most important original references on Anglo-Saxon history.
