Aet. ii. 1; _Dox._ 327. Anaximandros (et al.): Infinite worlds exist in the infinite in every cycle; _Dox._ 329, and these worlds are equally distant from each other. 4; 331. The world is perishable. 11; 340. Anaximandros: The heavens arise from a mixture of heat and cold. 13; 342. The stars are wheel-shaped masses of air, full of fire, breathing out flames from pores in different parts. 15; 345. Anaximandros et al.: The sun has the highest position of all, the moon is next in order, and beneath it are the fixed stars and the planets. 16; 345. The stars are carried on by the circles and the spheres in which each one moves. 20; 348. The circle of the sun is twenty-eight times as large as the earth, like a chariot wheel, having a hollow centre and this full of fire, shining in every part, and sending out fire through a narrow opening like the air from a flute. 21; 351. The sun is equal in size to the earth, but the circle from which it sends forth its exhalations, and by which it is borne through the heavens, is twenty-seven times as large as the earth. 24; 354. An eclipse takes place when the outlet for the fiery exhalations is closed. 25; 355. The circle of the moon is nineteen times as large as the earth, and like the circle of the sun is full of fire; and eclipses are due to the revolutions of the wheel; for it is like a chariot wheel, hollow inside, and the centre of it is full of fire, but there is only one exit for the fire. 28; 358. The moon shines by its own light. 29; 359. The moon is eclipsed when the hole in the wheel is stopped. Aet. iii. 3; _Dox._ 367. Anaximandros said that lightning is due to wind; for when it is surrounded and pressed together by a thick cloud and so driven out by reason of its lightness and rarefaction, then the breaking makes a noise, while the separation makes a rift of brightness in the darkness of the cloud. Aet. iv. 3; _Dox._ 387. Anaximandros et al.: The soul is like air in its nature. Aet. v. 19; _Dox._ 430. Anaximandros said that the first animals were generated in the moisture, and were covered with a prickly skin; and as they grew older, they became drier, and after the skin broke off from them, they lived for a little while. Cic. _de Nat. Deor._ i. 10; _Dox._ 531. It was the opinion of Anaximandros that gods have a beginning, at long intervals rising and setting, and that they are the innumerable worlds. But who of us can think of god except as immortal? III. _ANAXIMENES._ Anaximenes of Miletos, son of Eurystratos, was the pupil or companion of Anaximandros. According to Apollodoros, quoted by Diogenes, he was born in the sixty-third Olympiad (528-524 B.C.). Diels[16] has, however, made it seem probable that this date refers to his prime of life, rather than to his birth. Of his life nothing is known.
