De primo Saxonum adventu is a historical work, probably written in Durham during the episcopate of Ranulf Flambard (1099–1128). It recounts the coming of the English (called the "Saxons") to Great Britain, treating individually the history of the rulers of the Kingdom of Kent, the Kingdom of East Anglia, the Kingdom of Northumbria (to Erik Bloodaxe), as well as the archbishops of Canterbury and the archbishops of York, the bishops of Durham and the earls of Northumbria.
