The Copernican System that of the Ancients.
Copernicus places the sun in the centre of our system, the fixed stars at the circumference, and the earth and other planets in the intervening space; and he ascribes to the earth not only a diurnal motion around its axis, but an annual motion round the sun. This simple system, which explains all the appearances of the planets and their situations, whether processional, stationary, or retrograde, was so fully and distinctly inculcated by the ancients, that it is matter of surprise it should derive its name from a modern philosopher.
Pythagoras thought that the earth was a movable body, and, so far from being the centre of the world, performed its revolutions around the region of fire, that is the sun, and thereby formed day and night. He is said to have obtained this knowledge among the Egyptians, who represented the sun emblematically by a beetle, because that insect keeps itself six months under ground, and six above; or, rather, because having formed its dung into a ball, it afterwards lays itself on its back, and by means of its feet whirls that ball round in a circle.
Philolaüs, the disciple of Pythagoras, was the first publisher of that and several other opinions belonging to the Pythagorean school. He added, that the earth moved in an oblique circle, by which, no doubt, he meant the zodiac.
Plutarch intimates, that Timæus Locrensis, another disciple of Pythagoras, held the same opinion; and that when he said the planets were animated, and called them the different measures of time, he meant no other than that they served by their revolutions to render time commensurable; and that the earth was not fixed to a spot, but was carried about by a circular motion, as Aristarchus of Samos, and Seleucus afterwards taught.
