CHAP. 20. (22.)—OF THE HARMONY OF THE STARS.
Pythagoras, employing the terms that are used in music, sometimes names the distance between the Earth and the Moon a tone; from her to Mercury he supposes to be half this space, and about the same from him to Venus. From her to the Sun is a tone and a half; from the Sun to Mars is a tone, the same as from the Earth to the Moon; from him there is half a tone to Jupiter, from Jupiter to Saturn also half a tone, and thence a tone and a half to the zodiac. Hence there are seven tones, which he terms the diapason harmony[259], meaning the whole compass of the notes. In this, Saturn is said to move in the Doric time, Jupiter in the Phrygian[260], and so forth of the rest; but this is a refinement rather amusing than useful.
