a source for the affairs of the East Anglian church, and Bishop Cynibert for information about Lindsey. The historian Walter Goffart argues that Bede based the structure of the Historia on three works, using them as the framework around which the three main sections of the work were structured. For the early part of the work, dealing with the time up to the Gregorian mission of Augustine of Canterbury, Goffart asserts that Bede used Gildas's De excidio. The second section, detailing the Gregorian mission, was framed on the anonymous Life of Gregory the Great written at Whitby. The last section, describing events after the Gregorian mission, Goffart says was modelled on Stephen of Ripon's Life of Wilfrid. Most of Bede's informants for information after Augustine's mission came from the eastern part of Britain, leaving significant gaps in the knowledge of the western areas, which were those areas likely to have a native Briton presence. Contents The Ecclesiastical History has a clear polemical and didactic purpose. Bede sets out not just to tell the story of the English, but to advance his views on politics and religion. In political terms he is a partisan of his native Northumbria, amplifying its role in English history over and above that of Mercia, its great southern rival. He takes greater pains in describing events of the seventh century, when Northumbria was the dominant Anglo-Saxon power than the eighth, when it was not. The only criticism he ventures of his native Northumbria comes in writing about the death of King Ecgfrith in fighting the Picts at Nechtansmere in 685. Bede attributes this defeat to God's vengeance for the Northumbrian attack on the Irish in the previous year. For while Bede is loyal to Northumbria he shows an even greater attachment to the Irish and their missionaries, whom he considers to be far more effective and dedicated than their rather complacent English counterparts. His final preoccupation is over the precise date of Easter, which he writes about at length. It is here, and only here, that he ventures some criticism of St Cuthbert and the Irish missionaries, who celebrated the event, according to Bede, at the wrong time. In the end he is pleased to note that the Irish Church was saved from error by accepting the correct date for Easter. Models Bede's stylistic models included some of the same authors from whom he drew the
