 imagine. Below this is Mercury (called by the Greeks Στίλβων), which performs the same course in little less than a year, and is never farther distant from the sun than the space of one sign, whether it precedes or follows it. The lowest of the five planets, and nearest the earth, is that of Venus (called in Greek Φωσόρος). Before the rising of the sun, it is called the morning-star, and after the setting, the evening-star. It has the same revolution through the zodiac, both as to latitude and longitude, with the other planets, in a year, and never is more than two signs from the sun, whether it precedes or follows it.

XXI. I cannot, therefore, conceive that this constant course of the planets, this just agreement in such various motions through all eternity, can be preserved without a mind, reason, and consideration; and since we may perceive these qualities in the stars, we cannot but place them in the rank of Gods. Those which are called the fixed stars have the same indications of reason and prudence. Their motion is daily, regular, and constant. They do not move with the sky, nor have they an adhesion to the firmament, as they who are ignorant of natural philosophy affirm. For the sky, which is thin, transparent, and suffused with an equal heat, does not seem by its nature to have power to whirl about the stars, or to be proper to contain them. The fixed stars, therefore, have their own sphere, separate and free from any conjunction with the sky. Their perpetual courses, with that admirable and incredible regularity of theirs, so plainly declare a divine power and mind to be in them, that he who cannot perceive that they are also endowed with divine power must be incapable of all perception whatever.

In the heavens, therefore, there is nothing fortuitous, unadvised, inconstant, or variable: all there is order, truth, reason, and constancy; and all the things which are destitute of these qualities are counterfeit, deceitful, and erroneous, and have their residence about the earth beneath the moon, the lowest of all the planets.
