Testimonium 1 (Hippolytus, Refutation i. 9)
Archelaos was by birth an Athenian, and the son of Apollodoros. He spoke of the mixture of matter in a similar way to Anaxagoras, and of the first principles likewise. He held, however, that there was a certain nnxture immanent even in Nous. And he held that there were two efficient causes which were separated off from one another, namely, the warm and the cold. The former was in motion, the latter at rest. When the water was liquefied it flowed to the centre, and there being burnt up it turned to earth and air, the latter of which was borne upwards, while the former took up its position below. These, then, are the reasons why the earth is at rest, and why it came into being. It lies in the centre, being practically no appreciable part of the universe. (But the air rules over all things),* being produced by the burning of the fire, and from its original combustion comes the substance of the heavenly bodies. Of these the sun is the largest, and the moon second ; the rest are of various sizes. He says that the heavens were inclined, and that then the sun made light upon the earth, made the air transparent, and the earth dry ; for it was originally a pond, being high at the circumference and hollow in the centre. He adduces as a proof of this hollowness that the sun does not rise and set at the same time for all peoples, as it ought to do if the earth were level.

Testimonium 2 (Hippolytus, Refutation i. 9)
As to animals, he says that when the earth was first being warmed in the lower part where the warm and the cold were mingled together, many living creatures appeared, and especially men, all having the same manner of life, and deriving their sustenance * 'Apaay6peL0L are mentioned by Plato [Cra. 409 b 6), and in the Awro-ol \6yo(, (of. p. 29, «. 3). It is also to be noted that Plato {Farm, 126 a, b) represents certain <j>CK6<To<pot. from Klazomenai as coining to Athens after the deatb of Sokrates for the purpose of getting an accurate account of the famous conversation between Parmenides and the young Sokrates (§ 84) « from the slime ; they did not live long, and later on generation from one another began. And men were distinguished from the rest, and set up leaders, and laws, and arts, and cities, and so forth. And he says that Nous is implanted in all animals alike ; for each of the animals, as well as man, makes use of Nous, but some quicker and some slower.
