CHAPTER XXIX. OF THE ECLIPSE OF THE MOON.
Anaximenes believes that the mouth of the wheel, about which the moon is turned, being stopped is the cause of an eclipse. Berasus, that it proceeds from the turning of the dark side of the lunar orb towards us. Heraclitus, that it is performed just after the manner of a boat turned upside downwards. Some of the Pythagoreans say, that the splendor arises from the earth, its obstruction from the Antichthon (or counter-earth). Some of the later philosophers, that there is such a distribution of the lunar flame, that it gradually and in a just order burns until it be full moon; in like manner, that this fire decays by degrees, until its conjunction with the sun totally extinguisheth it. Plato, Aristotle, the Stoics, and all the mathematicians agree, that the obscurity with which the moon is every month affected ariseth from a conjunction with the sun, by whose more resplendent beams she is darkened; and the moon is then eclipsed when she falls upon the shadow of the earth, the earth interposing between the sun and moon, or (to speak more properly) the earth intercepting the light of the moon.
CHAPTER XXX. OF THE PHASES OF THE MOON, OR THE LUNAR ASPECTS; OR HOW IT COMES TO PASS THAT THE MOON APPEARS TO US TERRESTRIAL.
The Pythagoreans say, that the moon appears to us terraneous, by reason it is inhabited as our earth is, and in it there are animals of a larger size and plants of a rarer beauty than our globe affords; that the animals in their virtue and energy are fifteen degrees superior to ours; that they emit nothing excrementitious; and that the days are fifteen times longer. Anaxagoras, that the reason of the inequality ariseth from the commixture of things earthy and cold; and that fiery and caliginous matter is jumbled together, whereby the moon is said to be a star of a counterfeit aspect. The Stoics, that on account of the diversity of her substance the composition of her body is subject to corruption.
