Celestial Harmony, a sort of music much talked of by many of the ancient philosophers and fathers, and supposed to have been produced by the sweetly-tuned motions of the stars and planets. This harmony they attributed to the various proportionate impressions of the heavenly globes upon one another, acting at proper intervals. It is impossible, according to them, that such prodigiously large bodies, moving with so much rapidity, should be silent. On the contrary, the atmosphere, continually impelled by them, must yield a set of sounds proportionate to the impression it receives; and as they do not all run the same circuit, nor revolve with the same velocity, the different tones arising from the diversity of motions, directed by the hand of the Almighty, must form an admirable symphony or concert. They therefore supposed that the moon, as being the lowest of the planets, corresponded to mi, Mercury to fa, Venus to sol, the Sun to la, Mars to si, Jupiter to ut, Saturn to re, and the orb of the fixed stars, as being the highest of all, to mi, or the octave.
