‘From Material To Immaterial Things'

Near the top of the easternmost window of Canterbury Cathedral, there is an image of God leaning down from heaven to hand Moses the Tablets of the Law (Figure 15.1). Any medieval person looking at this window would, or at least should, have known that part of the first commandment inscribed on these tablets was, ‘Thou shalt not make thyself a graven thing, nor the likeness of any thing that is in heaven above, or in earth beneath, nor of those things that are in the waters under the earth.’¹
