God bestowed upon them, to measure and arrange in their respective stations the heavenly bodies, other nations more gross and unintelligent made no advance towards imitating them. These childish and savage populations imagined the earth to be flat, supported, I know not how, by its own weight in the air; the sun, moon, and stars to move continually upon a solid vaulted roof called a firmament; and this roof to sustain waters, and have flood-gates at regular distances, through which these waters issued to moisten and fertilize the earth. But how did the sun, the moon, and all the stars reappear after their setting? Of this they know nothing at all. The heaven touched the flat earth: and there were no means by which the sun, moon, and stars could turn under the earth, and go to rise in the east after having set in the west. It is true that these children of ignorance were right by chance in not entertaining the idea that the sun and fixed stars moved, round the earth. But they were far from conceiving that the sun was immovable, and the earth with its satellite revolving round him in space together with the other planets. Their fables were more distant from the true system of the world than darkness from light. They thought that the sun and stars returned by certain unknown roads after having refreshed themselves for their course at some spot, not precisely ascertained, in the Mediterranean Sea. This was the amount of astronomy, even in the time of Homer, who is comparatively recent; for the Chaldæans kept their science to themselves, in order to obtain thereby, greater respect from other nations. Homer says, more than once, that the sun plunges into the ocean--and this ocean, be it observed, is nothing but the Nile--here, by the freshness of the waters, he repairs during the night the fatigue and exhaustion of the day, after which, he goes to the place of his regular rising by ways unknown to mortals.…
