The triptych form arises from early Christian art, and was a popular standard format for altar paintings from the Middle Ages onwards. Its geographical range was from the eastern Byzantine churches to the Celtic churches in the west. Renaissance painters such as Hans Memling and Hieronymus Bosch used the form. Sculptors also used it. Triptych forms also allow ease of transport.
This triptych stained glass window is made to depict three major events in the life of Christ displayed in one scene, the baptism of Christ, the resurrection of Christ , and the Pieta. John the Baptist appears in the water with Jesus, Jesus rises surrounded by the soldiers, and Mary displayed with her son.
