In Cicero’s On the Commonwealth, Scipio has a dream of heaven where he goes to visit his grandfather. While there, he is entranced by the music of the spheres. Sadly, he learns that men have lost the ability to hear it, though it is everywhere:
Men’s ears have been filled with this sound and consequently grown deaf to it. You have no duller sense than hearing, just as at the point where the Nile plunges from high mountains at the place called Cataract, the race of men that lives there is completely deaf because of the magnitude of the sound. The sound made by the rapid revolution of the universe is so great that human ears cannot grasp it, just as you are unable to look directly into the Sun, because your sight and sense are overcome by its rays.
