during the Hellenistic period one can begin to speak of a “new cosmology,” which was related to a fundamental shift in the human perception of his place.19 In this cosmology the earth is the center and lowest level of a vast and expanded universe. It is surrounded by planetary spheres or “heavens,” usually seven in number, each dominated by its respective powers.20 Below the moon, the first of these spheres, is the “air,” the abode of various spirits or daimones. Above the highest sphere is the pure dwelling of God.
