The Transfiguration marks the moment when Christ’s divine nature is revealed to the disciples Peter, James, and John upon Mount Tabor. It is a key theophany within Christian iconography, uniting Old Testament prophecy with New Testament revelation and providing a vision of Christ in glory. Artists across the medieval and modern periods depict the event with consistent elements: Christ radiant at the centre, flanked by Moses and Elijah, with the disciples overwhelmed by the vision.

The Hardman window (1892) in Tewkesbury Abbey presents one of the finest late-Victorian treatments of the subject, combining traditional Gothic layout with the firm’s characteristic colour palette and dense ornamental framing.
