It remained for the Demiurgus,--in order that the Kosmos might become a full copy of its model the Generic Animal or Idea of Animal,--to introduce into it those various species of animals which that Idea contained. He first peopled it with Gods: the eldest and earliest of whom was the Earth, planted in the centre as sentinel over night and day: next the fixed stars, formed for the most part of fire, and annexed to the circle of the Same or the exterior circle, so as to impart to it light and brilliancy. Each star was of spherical figure and had two motions,--one, of uniform rotation peculiar to itself,--the other, an uniform forward movement of translation, being carried along with the great outer circle in its general rotation round the axis of the Kosmos.[41] It is thus that the sidereal orbs, animated beings eternal and divine, remained constantly turning round in the same relative position: while the sun, moon, and planets, belonging to the inner circles of the Different, and trying to revolve by their own effort in the opposite direction to the outer sphere, became irregular in their own velocities and variable in their relative positions.[42] The complicated movements of these planetary bodies, alternately approaching and receding--together with their occultations and reappearances, full of alarming prognostic as to consequences--cannot be described without having at hand some diagrams or mechanical illustrations to refer to.[43] [Footnote 41: Plato, Timæus, p. 40.] [Footnote 42: Plato, Timæus, p. 40 B.

His acquiescence in tradition.] Such were all the primitive Gods visible and generated[44] by the Demiurgus, to preside over and regulate the Kosmos. By them are generated, and from them are descended, the remaining Gods. [Footnote 44: Plato, Timæ. p. 40 D. [Greek: theô=n o(ratô=n kai\ gennêtô=n].]
