Libellus de exordio atque procursu istius, hoc est dunhelmensis, ecclesie -

The text edited and translated here for the first time for over a century is the most complete and detailed account of the church of Durham down to the early twelfth century. It is also important in the study of historical writing after the Norman Conquest, especially as recent research has cast considerable light on the identity and activities of its author, Symeon of Durham.
