The identity of these three figures is not in doubt as all three are labelled. St John of Beverley and St Egbert belong to the story of Christianity in the north during the Anglo-Saxon period. John succeeded Wilfrid as bishop of York and founded the monastery at Beverley. Egbert also occupied the see of York. Calixtus is chronologically the ‘odd-man-out’ in this panel, but was probably chosen as the Pope who consecrated Archbishop Thurstan in 1119. It was Thurstan who refused to swear an oath of obedience to Canterbury, thereby ending the primacy dispute.
