The Book of Isaiah presents Jesse, an ancestor of Jesus, as the root of a great tree, a symbol of his illustrious progeny. In this thirteenth century stained glass panel from Swabia in southern Germany, Jesse lies asleep at the bottom, and the tree rises, as in his dream, from his side. In branches coiling from the trunk, prophets hold scrolls that foretell the coming of Christ. King David holds a harp in the roundelimmediately above Jesse, and the four upper roundels contain scenes from the life of Jesus, from bottom to top: the Presentation in the Temple, the Last Supper, the Crucifixion, and the Ascension. The vertical trunk unifies the panel and seems to merge with the wood of the cross in the Crucifixion scene.
