Willelmi Malmesbiriensis Monachi De gestis pontificum Anglorum libri quinque - William of Malmesbury - Bog

Originally published in 1870 as part of the Rolls Series, this is an ecclesiastical history of England up until 1122. William of Malmesbury was a prolific and trustworthy chronicler; his largely contemporary record holds the distinction of being as much a history as a primary source in its own right.
