These Sirens sing for their pleasure divine and heavenly tunes, and accompany their sacred circuit and dance with an harmonious song of eight notes. Nor was there necessity of a fuller chorus, in regard that within the confines of eight notes lay the first bounds and limits of all duple and triple proportions; the unit being added to both the even and odd numbers. And certainly from hence it was that the ancients raised their invention of nine Muses; of which eight were employed in celestial affairs, as Plato said; the ninth was to take care of things terrestrial, and to reduce and reform the inequality and confusion of error and jarring variance. 33. Now then consider whether the soul does not roll and turn and manage the heavens and the celestial bodies by means of those harmonious concords and equal motions that are wrought and fermented within her, being herself most wise and most just. And such she became by virtue of harmonical proportions, whose images representing things incorporeal are imprinted into the discernible and visible parts and bodies of the world. But the chief and most predominating power is visibly mixed in the soul, which renders her harmonious and obedient to herself, the other parts unanimously yielding to her as the most supreme and the divinest part of all. For the Sovereign Artificer and Creator finding a strange disorder and erroneous confusion in the motions of the decomposed and unruly soul, which was still at variance with herself, some things he divided and separated, others he brought together and reconciled to a mutual sympathy, making use of harmony and numbers. By virtue of which, the slightest and meanest of insensible substances, even stocks and stones, the rinds of trees, and sometimes even the rennets of beasts, by various mixtures, compositions, and temperatures, may become the charming objects of the sight, or afford most pleasing perfumes and wholesome medicaments for the relief of mankind, or be wrought and hollowed to send forth pleasing musical sounds. And for this reason it was that Zeno of Citium encouraged and persuaded youth to frequent the theatres, there to observe the variety of melodious sounds that proceeded from horns or cornets, wooden hautboys, flutes and reeds, or any other musical instruments to which the contrivance of art had rightly applied the reason of number and proportion. Not that we will here maintain, with the Pythagoreans, that all things resemble number, for that requires a long discourse to prove it. But where mutual society and sympathy arise out of discord and dissimilitude, that the cause of this is moderation and order, produced by the power of harmony and number, was a thing not concealed even from the poets. And these give to what is friendly and kind the epithet “evenly fitted;” while, on the other side, men of rugged and malicious dispositions they called “unevenly tempered,” as if enmity and discord were nothing but a sort of a disproportion.
