A particular concern in the
Historia is the legendary foundation of the abbey, and the author stressed the fact that the abbey was founded much earlier than its refoundation by
Æthelwold in the 10th century. He based his account in the
Historia on
Geoffrey of Monmouth's work
Historia Regum Britanniae, tracing the first foundation of Abingdon to an Irish monk supposedly named
Abbennus, who founded the abbey on the Mount of Abbennus in Berkshire. Other sources besides Geoffrey of Monmouth included
Ælfric's
Vita Sancti Æthelwoldi. Also included was a list of the abbey's relics that had originally been compiled by Abbot
Faricius. However, up until the
Norman Conquest, the History is primarily concerned with charters and land documents; indeed,
Gransden has described it as “little more than an inflated
cartulary”. There are rare narrative sections concerning major events, presumably drawn from various chronicles, as mentioned above. One important part of the
Historia is the description of the collapse of one of the abbey church's towers in 1091. The chronicle records that the monks were celebrating
matins, which would normally have been done in the abbey church, but on this occasion, the
prior had decided to have the office celebrated in the
chapter house instead, which allowed all the monks to escape the collapse unharmed. The Author, although unknown, displays certain partisan opinions of some events. Presumably a monk of English descent (as he could read the Old English of the Anglo-Saxon Chronicle), he displays a certain hostility to the Danes but not a particularly hostile one towards Normans in general, except to those who cause the Abbey to suffer, such as the “Imperious Queen”
Matilda. In general, as might be expected, he is hostile to all who oppose the Abbey. ==Land Laws==
