Aet. _Plac._ ii. 1; _Dox._ 328. Empedokles: The course of the sun is the outline of the limit of the universe. ii. 4; 331. Empedokles: The universe <arises and> perishes according to the alternating rule of Love and Strife. ii. 6; 334. Empedokles: The aether was first separated, and secondly fire, and then earth, from which, as it was compressed tightly by the force of its rotation, water gushed forth; and from this the air arose as vapour, and the heavens arose from the aether, the sun from the fire, and bodies on the earth were compressed out of the others. ii. 7; 336. Empedokles: Things are not in fixed position throughout the all, nor yet are the places of the elements defined, but all things partake of one another. ii. 8; 338. Empedokles: When the air gives way at the rapid motion of the sun, the north pole is bent so that the regions of the north are elevated and the regions of the south depressed in respect to the whole universe. ii. 10; 339. Empedokles: The right side is toward the summer solstice, and the left toward the winter solstice. ii. 11; 339. Empedokles: The heaven is solidified from air that is fixed in crystalline form by fire, and embraces what partakes of the nature of fire and of the nature of air in each of the hemispheres. ii. 13; 341. Empedokles: The stars are fiery bodies formed of fiery matter, which the air embracing in itself pressed forth at the first separation. 342. The fixed stars are bound up with the crystalline (vault), but the planets are set free. ii. 20; 350. Empedokles: There are two suns; the one is the archetype, fire in the one hemisphere of the universe, which has filled that hemisphere, always set facing the brightness which corresponds to itself; the other is the sun that appears, the corresponding brightness in the other hemisphere that has been filled with air mixed with heat, becoming the crystalline sun by reflection from the rounded earth, and dragged along with the motion of the fiery hemisphere; to speak briefly, the sun is the brightness corresponding to the fire that surrounds the earth. ii. 21; 351. The sun which faces the opposite brightness, is of the same size as the earth. ii. 23; 353. Empedokles: The solstices are due to the fact that the sun is hindered from moving always in a straight line by the sphere enclosing it, and by the tropic circles. ii. 24; 354. The sun is eclipsed when the moon passes before it. ii. 25; 357. Empedokles: The moon is air rolled together, cloudlike, its fixed form due to fire, so that it is a mixture. ii. 27; 358. The moon has the form of a disk. ii. 28; 358. The moon has its light from the sun. ii. 31; 362. Empedokles: The moon is twice as far from the sun as it is from the earth (?) 363. The distance across the heavens is greater than the height from earth to heaven, which is the distance of the moon from us; according to this the heaven is more spread out, because the universe is disposed in the shape of an egg.
