Just as we need to deconstruct texts, we also need to deconstruct images.
This image features Emperor Alexius I Comnenus before Christ. Jesus is seated on the throne (indicating his lordship over the Emperor) with his right hand in a benediction gesture (indicating his blessing on the Emperor). The Emperor himself is illuminated by a halo, indicating holiness.
The question that arises for me is, what is the impact this would have had on the audience for which it was originally intended? What is it saying theologically and politically?
