Here we encounter the portrait of Abbot Suger via his account of how and why he built Saint-Denis, what is portrayed on the West façade of the cathedral, and how the doctrine of God as light, encountered in a book which had come from Byzantium to the abbey centuries earlier, was translated into architectural form. We see some of the objects that are part of the treasury of Saint-Denis and discuss the Abbot’s notion of “anagogical uplift” as a way of moving—via stained glass—between the Old and New Testaments and from the material to the spiritual plane.
