 The refounders of the Abbey are not completely clear; however in a document of 1535 (drawn up following the "Valor Ecclesiasticus"), Centwine, Ine, Æthelstan and Æthelred are claimed as founders.Tradition suggests that Æthelstan's contribution was penance for the murder of Atheling Edwin in 933 or following victory at the Battle of Brunanburh in 937.The charter of King Ine is known to be a forgery, however it may have some basis in fact.
