Besides the chaotic matter and the ideas or forms of the four elements, as yet unrealized in the actual substances of fire, air, earth, and water, there were coeval ideas or forms of animals, or, as we should say, abstract animals, or conceptions of animals. The first and grandest of these was the eternal self-animal, or the ideal of animal existence. Next came the ideas or forms of four other animals: 1. The celestial gods; 2. Man; 3. Birds, or animals living in air; 4. Land or water animals. Bearing in mind that we are still in the region of abstract conceptions in regard to these types of animals, which as yet have no concrete existence, and that they are, so to speak, the intellectual models from which the Demiurgus is to work, in order to make the real animals conformably to the pre-existing and eternal plan, we come to the process of forming the Kosmos, which is to be the containing animal of all the other four. Out of the confused chaos of existing matter the Demiurgus proceeds to construct the Kosmos, which was to become the one self-animal, by impressing the idea or abstract form of animal upon a physical structure built out of the primordial chaotic matter and comprehending the whole of it. The first step was to bring the four elements of fire, air, earth, and water out of their chaotic and confused condition by separating them according to the forms of their eternal ideas. The total of each element, when made to take its normal form, was used in the construction of the Kosmos, which thus came to possess the whole existing body of material; "so that," to borrow the words of Mr. Grote, "there remained nothing of the four elements apart, to hurt the Kosmos from without, nor anything as raw material for a second Kosmos." The Kosmos was made a perfect sphere, and with a perfectly smooth outer surface, without organs of sight or hearing, because there was nothing outside to be seen or heard; without organs of respiration, because there was no outside atmosphere to be breathed; and without nutritive or excrementory organs, because it was self-sufficing, being supplied with nourishment by its own decay. It was not furnished with limbs or means of locomotion or standing, because, being a sphere turning on an axis, and having only one of the seven possible varieties of movement, namely, rotation in a circle in one and the same plane, there was nothing for it to grasp or repel.[12] This body, the only-begotten, because in its formation all existing bodily material was employed, perfectly spherical and smooth, equidistant from its center to all points of its circumference, and suspended upon its own axis traversing its diameter, was now to be animated by a soul.
