This is from the House of the Holy Sepulche. I can't help to point out that the sun is on the floor, and the Sun of God is over the sun. The pagans are no longer the dominate religion. God gave his Son for man, and he alone is the light of the world.
Oh I love how the play on words just shook things up. Images are what the "common" people knew. Most people did not know how to read, so images drove the point home. Even today we are very visual people. Art is very emotional for us. Some things we just love or hate. It illicits a response in us to our core. We still make snap judgements about people in an instant and don't even realize it. There is an unconscious judgement that we make and don't even realize it.
Images are powerful even today!
