The conflagration is followed by a cosmony that restores the cosmos. In fact, a permanent end would be impossible given the rationality of the early Stoic god. In this chapter, I limit myself to asking what is the structure of the cosmogony. How, exactly, is the large mass of fire left by the conflagration transformed in the cosmogony into the differentiated masses of air, fire, water and earth that constitute the present cosmos? I shall argue that the cosmogony, which sets off as soon as the conflagration is over, divides into at least three basic stages: (a) the formation of the four elements and of the sublunary and supralunary regions as two differentiated parts of the cosmos, (b) the formation of composite homogeneous substances (gold, flesh, wood, etc.) out of the four elements; and (c) the formation of composite heterogeneous substances (animals and plants) out of homogeneous ones.
