CHAPTER XLVII ---- OF THE COURSE AND MOTION OF THE STARS.
'ANAXAGORAS, Democritus, Cleanthes: all the fixed stars pass from east to west.
'Alcmaeon and the Mathematicians: the planets move in an opposite direction to the fixed stars; for theirs is the contrary course from west to east.
'Anaximander: they are borne along by the circles and spheres on which they are each set.
'Anaximenes: the stars do not revolve beneath the Earth, but around it.
'Plato and the Mathematicians: the Sun, the Day-star, and Stilbon (Venus and Mercury) have equal orbits.'
