Religion in the form of polytheism entered the world as the vindication of power. Not only was there no separation of church and state; religion was the transcendental justification of the state. Why was there hierarchy on earth? Because there was hierarchy in heaven. Just as the sun ruled the sky, so the pharaoh, king or emperor ruled the land. When some oppressed others, the few ruled the many, and whole populations were turned into slaves, this was - so it was said - to defend the sacred order written into the fabric of reality itself. Without it, there would be chaos. Polytheism was the cosmological vindication of the hierarchical society. Its monumental buildings, the ziggurats of Babylon and pyramids of Egypt, broad at the base, narrow at the top, were hierarchy's visible symbols. Religion was the robe of sanctity worn to mask the naked pursuit of power.
