can see only the appearances of things, and not things themselves. We are no more deceived when the sun, the work of the divinity – that star a million times larger than our earth – appears to us quite flat and two feet in width, than when, in a convex mirror, which is the work of our own hands, we see a man only a few inches high.
If the Chaldæan magi were the first who employed the understanding which 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. This idea is very like that of Baron Fœneste, who says, that the cause of our not seeing the sun when he goes back, is that he goes back by night.
As, at that time, the nations of Syria and the Greeks were somewhat acquainted with Asia and a small part of Europe, and had no notion of the countries which lie to the north of the Euxine Sea and to the south of the Nile, they laid it down as a certainty that the earth was a full third longer than it was wide; consequently the heaven, which touched the earth and embraced it, was also longer than it was wide. Hence came down to us degrees of longitude and latitude, names which we have always retained, although with far more correct ideas than those which originally suggested them.
The Book of Job, composed by an ancient Arab who possessed some knowledge of astronomy, since he speaks of the constellations, contains nevertheless the following passage: "Where wert thou, when I laid the foundation of the earth? Who hath taken the dimensions thereof? On what are its foundations fixed? Who hath laid the cornerstone thereof?"
The least informed schoolboy, at the present day, would tell him, in answer: "The earth has neither cornerstone nor foundation; and, as to its dimensions, we know them perfectly well, as from Magellan to Bougainville, various navigators have sailed round it."
The same schoolboy would put to silence the pompous declaimer Lactantius, and all those who before and since his time have decided that the earth was fixed upon the water, and that there can be no heaven under the earth; and that, consequently, it is both ridiculous and impious to suppose the existence of antipodes.
It is curious to observe with what disdain, with what contemptuous pity, Lactantius looks down upon all the philosophers, who, from about four hundred years before his time, had begun to be acquainted with the apparent revolutions of the sun and planets, with the roundness of the earth, and the liquid and yielding nature of the heaven through which the planets revolved in their orbits, etc. He inquires, "by what degrees philosophers attained such excess of folly as to conceive the earth to be a globe, and to surround that globe with heaven." These reasonings are upon a par with those he has adduced on the subject of the sibyls.
Our young scholar would address some such language as this to all these consequential doctors: "You are to learn that there are no such things as solid heavens placed one over another, as you have been told; that there are no real circles in which the stars move on a pretended firmament; that the sun is the centre of our planetary world; and that the earth and the planets move round it in space, in orbits not circular but elliptical. You must learn that there is, in fact, neither above nor below, but that the planets and the comets tend all towards the sun, their common centre, and that the sun tends towards them, according to an eternal law of gravitation."
Lactantius and his gabbling associates would be perfectly astonished, were the true system of the world thus unfolded to them.
HEAVEN OF THE ANCIENTS
Were a silkworm to denominate the small quantity of downy substance surrounding its ball, heaven, it would reason just as correctly as all the ancients, when they applied that term to the atmosphere; which, as M. de Fontenelle has well observed in his "Plurality of Worlds," is the down of our ball.
The vapors which rise from our seas and land, and which form the clouds, meteors, and thunder, were supposed, in the early ages of the world, to be the residence of gods. Homer always makes the gods descend in clouds of gold; and hence painters still represent them seated on a cloud. How can any one be seated on water? It was perfectly correct to place the master of the gods more at ease than the rest; he had an eagle to carry him, because the eagle soars higher than the other birds.
The ancient Greeks, observing that the lords of cities resided in citadels on the tops of mountains, supposed that the gods might also have their citadel, and placed it in Thessaly, on Mount Olympus, whose summit is sometimes hidden in clouds; so that their palace was on the same floor with their heaven.
Afterwards, the stars and planets, which appear fixed to the blue vault of our atmosphere, became the abodes of gods; seven of them had each a planet, and the rest found a lodging where they could. The general council of gods was held in a spacious hall which lay beyond the Milky Way; for it was but reasonable that the gods should have a hall in the air, as men had town-halls and courts of assembly upon earth.
When the Titans, a species of animal between gods and men, declared their just and necessary war against these same gods in order to recover a part of their patrimony, by the father's side, as they were the sons of heaven and earth; they contented themselves with piling two or three mountains upon one another, thinking that would be quite enough to make them masters of heaven, and of the castle of Olympus.
Neve foret terris securior arduus æther,
Affectasse ferunt regnum celeste gigantes;
Attaque congestos struxisse ad sidera montes.
Nor heaven itself was more secure than earth;
Against the gods the Titans levied wars,
And piled up mountains till they reached the stars.
It is, however, more than six hundred leagues from these stars to Mount Olympus, and from some stars infinitely farther.
Virgil (Eclogue v, 57) does not hesitate to say: "Sub pedibusque videt nubes et sidera Daphnis."
Daphnis, the guest of heaven, with wondering eyes,
Views in the Milky Way, the Starry skies,
And far beneath him, from the shining sphere
Beholds the morning clouds, and rolling year.
But where then could Daphnis possibly place himself?
At the opera, and in more serious productions, the gods are introduced descending in the midst of tempests, clouds, and thunder; that is, God is brought forward in the midst of the vapors of our petty globe. These notions are so suitable to our weak minds, that they
