CHAPTER XV. OF THE ORDER AND PLACE OF THE STARS.
Xenocrates says that the stars are moved in one and the same superficies. The other Stoics say that they are moved in various superficies, some being superior, others inferior. Democritus, that the fixed stars are in the highest place; after those the planets; after these the sun, Venus, and the moon, in order. Plato, that the first after the fixed stars that makes its appearance is Phaenon, the star of Saturn; the second Phaeton, the star of Jupiter; the third the fiery, which is the star of Mars; the fourth the morning star, which is the star of Venus; the fifth the shining star, and that is the star of Mercury; in the sixth place is the sun, in the seventh the moon. Plato and some of the mathematicians conspire in the same opinion; others place the sun as the centre of the planets. Anaximander, Metrodorus of Chios, and Crates assign to the sun the superior place, after him the moon, after them the fixed stars and planets. CHAPTER XVI. OF THE MOTION AND CIRCULATION OF THE STARS. Anaxagoras, Democritus, and Cleanthes say that all the stars have their motion from east to west. Alcmaeon and the mathematicians, that the planets have a contrary motion to the fixed stars, and in opposition to them are carried from the west to the east. Anaximander, that they are carried by those circles and spheres on which they are placed. Anaximenes, that they are turned under and about the earth. Plato and the mathematicians, that the sun, Venus, and Mercury hold equal measures in their motions.
