Thus far we have the formation of the Kosmos, animated with a pervading soul, the body being formed out of the whole of existing matter, molded into the specific elements of fire, air, earth, and water, and the soul being formed out of the constituent ingredients furnished by the eternal and invisible essence of ideas. The whole, body and soul of the Kosmos, was thus an animal, formed on the abstract but eternal idea or form of an animal which had existed before time began. We now approach the formation of the other animals. Of the Kosmos there could be but one. All existing material of matter had been used in his construction. He could not become a species, as there could be no second Kosmos. Something could be borrowed from him, for the formation of other animals, but nothing could be destroyed. He was not yet, however, a full copy of the model of the Generic Animal or Idea of Animal, because the eternal plan of that model required that he should be peopled or inhabited by four other animals, which might constitute species. Accordingly, the Demiurgus proceeds to form the first of these sub-animals, the gods, who are to inhabit different portions of the Kosmos. The first of these in formation was the earth, planted in the center, and made sentinel over night and day; next the fixed stars, formed chiefly out of fire, and placed in the outer circle of a fixed revolution, or the Circle of the Same, to give to it light and brilliancy. The sidereal orbs thus became animated beings, eternal and divine. They remained constantly turning round in the same relative position, but the sun, moon, and planets, belonging to the Circle of the Different, and trying to revolve by their own effort in a direction opposite to that of the outer sphere, became irregular in their revolutions and varied in their relative positions. Thus the primitive gods were the earth and the fixed stars, which revolved without variation with the Circle of the Same, and became immortal as well as visible; while the sun, moon, and planets were not among the primitive gods, but were simply spherical bodies placed in the inner Circle of the Different. The primitive gods preside over and regulate the Kosmos. From them are generated and descended the remaining gods.[13]
