Dr. Jim Leary, the University of Reading archaeologist who led the exploration back in December 2016, stated as Phys Org reports : "Conventional wisdom placed the Montem Mound 500 years later, in the Norman period. But we have shown that it dates to between the 5th and 7th centuries, not long after the collapse of Roman Empire. This is a time of heroic myth and legend where archaeology fills the gaps of the historic record. This discovery will add so much more to our understanding of the people who lived in Britain at this time. It will also extend our knowledge of the history of Slough."
The Benedictine reform was led by St. Dunstan over the latter half of the 10th century. It sought to revive church piety by replacing secular canons- often under the direct influence of local landowners, and often their relatives- with celibate monks, answerable to the ecclesiastical hierarchy and ultimately to the Pope. This deeply split England, bringing it to the point of civil war, with the East Anglian nobility (such as Athelstan Half-King , Byrhtnoth ) supporting Dunstan and the Wessex aristocracy ( Ordgar , Æthelmær the Stout ) supporting the secularists These factions mobilsed around King Eadwig (anti-Dunstan) and his brother King Edgar (pro). On the death of Edgar, his son Edward the Martyr was assassinated by the anti-Dunstan faction and their candidate, the young king Æthelred was placed on the throne. However this "most terrible deed since the English came from over the sea" provoked such a revulsion that the secularists climbed down, although Dunstan was effectively retired.
