Æthelwig died on 16 February in either 1077 or 1078, and was memorialised in a work on his life that was later incorporated in the Chronicon Abbatiae de Evesham, a 13th-century history of the abbey and its abbots.[7] Æthelwig also served as a judge for King Edward the Confessor, at one point hearing a case at the royal court along with Wulfstan and Regenbald, the chancellor.[12] The fact that the Evesham's house chronicle appears to have been reworked after 1100 to gloss over embarrassing incidents of the abbots submitting to the bishops of Worcester makes evaluation of Æthelwig's relations with his episcopal superiors more difficult.[23] Æthelwig used his knowledge of English law not only on his own account, but to aid the new Norman ecclesiastics, such as Lanfranc, the Archbishop of Canterbury, and Serlo, the Abbot of Gloucester.[28] The Chronicon states that Æthelwig offered aid to the refugees because of his charitable nature, but it is possible that it was also part of his royal duties in western England.[30] Hemming, a medieval monastic writer from Worcester Priory, wrote of Æthelwig that he "surpassed everyone by his intelligence, his shrewdness and his knowledge of worldly law".[35] This was a 13th-century work by Thomas of Marlborough, which was written to bolster Evesham's case for exemption from the jurisdiction of the Bishops of Worcester, in whose diocese Evensham was.A large portion of the work is a detailed list of lands acquired by Æthelwig for the abbey, and concludes with a short description of the abbot's death.
