The universe itself they considered as a large sphere, and the intervals between the heavenly bodies they thought were determined according to the laws and relations of musical harmony. And from this theory arose the doctrine of the Music of the Spheres; as the heavenly bodies in their motion occasioned a sort of sound depending on their distances and velocities; and as these were determined by the laws of harmonic intervals, the sounds, or notes, formed a regular musical scale. The light and heat of the central fire he believed that we received through the sun, which he considered a kind of lens: and perfection, he conceived to exist in direct ratio to the distance from the central fire. The universe, itself, they looked upon as having subsisted from all eternity, controlled by an eternal supreme Deity; who established both limits and infinity; and whom they often speak of as the absolute μονὰς, or unity. He pervaded (though he was distinct from) and presided over the universe.
