Rh opinions of your poets about the gods. Therefore, since it is fit that we commence with the ancients and the earliest, beginning thence I will produce the opinion of each, much more ridiculous as it is than the theology of the poets.

Heraclitus and Hippasus, from Metapontus; say that fire is the first principle of all things; for from fire all things proceed, and in fire do all things terminate. Anaxagoras of Clazomenæ said that the homogeneous parts are the first principles of all things. Archelaus, the son of Apollodorus, an Athenian, says that the infinite air and its density and rarity are the first principle of all things.
