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 moved 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 have equal
measures in their motions.
