The History of the Church of Abingdon is one of the most valuable local histories produced in the twelfth century. It provides a wealth of information about, and great insight into, the legal, economic, and ecclesiastical affairs of a major monastery. Charters and narrative combine to provide a vital resource for historians. The present edition, unlike its victorian predecessor, is based on the earliest manuscript of the text. A modern English translation is provided on facing pages, together with extensive introductory material and historical notes. This volume covers the period from the reputed foundation of the abbey and its estates to c.1071. Volume II, already published, covers from c.1071- c.1164.
