- "The old imaginary antiearth (άγτιχϑωγ) of the Pythagoreans does not belong to the sphere of these conjectures. It and the Earth were supposed to have a parallel concentric movement; it was an idea devised to spare the Earth, which was supposed to perform around the central fire a planetary revolution in 24 hours, from having also to execute a movement of rotation, and, indead, represented no doubt the opposite hemisphere, or the antipodal half of our planet."
- "For the later Pythagoreans the world was made up of four elements: earth, water, air, and fire; the universe had a spherical earth traveling around in a circle once every 24 hours (instead of rotating); there was an invisible central fire, with the sun reflecting light from it; and in order to have exactly 10 major bodies in the universe, there was stipulated an antiearth, visible only from the back of the earth."
