Oh! replied the Marchioness; the sun and stars are made of fire, a swift motion is nothing to them, but the earth does not seem formed for motion. And should you think, I answered, if experience had not proved the fact, that a large ship, carrying a hundred and fifty pieces of cannon, three thousand men, and a heavy freight of merchandize, could be formed for motion?—Yet a gentle breeze is sufficient to move it forwards, because the water, being liquid, and easily divided, makes a very slight resistance to the progress of the ship, or if it be in the middle of a river, it follows without difficulty the current of the water, since there is then no impediment. In like manner the earth, notwithstanding its weight, is with facility carried through the sky which is infinitely more fluid than water, and which fills the immense space occupied by all the planets. To what could the earth be fastened so strongly as to resist the current of this celestial fluid and remain motionless? We might as well imagine a little wooden ball could resist the tide of a river.
But, said she, how can a body so ponderous as the earth be suspended in your celestial fluid, which from its great fluidity must be extremely light? It does not follow, I replied, that a substance must be extremely light because it is fluid. What do you think of the great ship we have been talking of, which, with all its lading, is lighter than the water that supports it? I won't have any more to say to you, answered she, half angrily, if you mention your ship again.[12] But tell me, is it not dangerous to inhabit such a whirli-gig as you represent the earth? If you are afraid, said I, let us have the world supported by four elephants, as the Indians do. Well! cried she, here is a new system. I like those people for providing such good foundations for the earth to rest on, whilst we Copernicans are imprudent enough to swim at random in this celestial fluid. I dare say if the Indians knew there was the least danger of the earth's being moved, they would double the number of elephants.
[12] The Marchioness was in the right not to listen to such an answer. It is absurd to pretend that the ætherial fluid, so light and rare, can be capable of bearing along those enormous masses, the planets.
It would be worth while, I replied, laughing at the thought, we must not be sparing of elephants if they can enable us to sleep in peace; if you would find them serviceable to-night we'll put as many as you please, and then remove them one or two at a time as you find your courage return. No, said she, I don't think there is any need for them, and to speak seriously, I feel courageous enough to let the world turn round. And I can venture to predict, answered I, that in a little while its turning will give you pleasure; will even inspire the most delightful ideas, I sometimes imagine myself raised above the surface of the earth, and remaining motionless whilst its daily rotation continues. All the different inhabitants pass in review; some fair, some copper-coloured, some black. Now I see heads covered with hats; then with turbans; some shaven, others with flowing hair. As the towns pass before me, I observe some have steeples, some long spires with crosses on them, others are ornamented with towers of porcelaine. Then I behold large countries with no other buildings than little huts: afterwards, immense seas; then frightful deserts; and in short, all the boundless variety which is to be found on the face of the earth.
Really, she replied, it would be worth while to devote four-and-twenty hours to such a sight. If I understand you, when we move, other countries with their inhabitants pass into the situation we are leaving, and so on, till in four-and-twenty hours we again arrive at the same place.
Copernicus himself, said I, could not have comprehended it more clearly. The first that would succeed us[13] would be the English: we should probably find them arguing on some political topic with less gaiety than we are discussing our philosophy. When we had dismissed them we should discover a vast sea,[14] on which perhaps would be some vessel, less at her ease than we. Then come the Iroquois, eating one of their prisoners of war, who does not even utter a groan though still alive when they begin to devour him.[15] After them the women of Jesso, who employ all their time in preparing victuals for their husbands, and painting their lips and eye-brows blue to appear handsome in the eyes of the most disgusting men in the world. Then the Tartars, very devoutly going on a pilgrimage to their high priest, who dwells in an obscure recess, enlightened only by lamps, the rays of which direct these votaries to the object of their adoration. Afterwards the beautiful Circassians who make no ceremony of granting all their favours to the first that solicits them, except what they believe the essential prerogative of their husbands. Then the inhabitants of Little Tartary, who go to steal women for the Turks and Persians. Last of all our countrymen, whom we should find entertaining each other with the vagaries of their imagination.
[13] To speak more properly they would be one hundred leagues northward.
[14] The Atlantic.
[15] We should next see the Pacific Ocean.
It is amusing enough, said the Marchioness, to fancy oneself in a situation to see all these things: but if I were taking the view I should wish for the power of hastening or retarding the earth's motion, according to the feelings with which each object inspired me: I assure you I should soon push on those that argued on politics, and the others that devoured their enemies; but there are some of the people you have been speaking of that would excite my curiosity; the handsome Circassians, for instance, whose customs are so peculiar. But a serious difficulty occurs to me respecting your system. If the earth turns, we every moment change our atmosphere, and respire that of a new climate. By no means, madam, I replied; the air which surrounds the earth rises only to a certain height, twenty leagues perhaps at farthest;[16] this atmosphere always turns with us. You have doubtless observed the sort of shell in which a silk-worm imprisons itself, and which it forms with such astonishing art. It is composed of silk closely woven, but covered with a light down. Thus it is with regard to the earth, it is a solid body covered with an atmosphere extending to a certain height, which adheres to, and moves with it, as the down does with the firmer substance beneath it. Above our atmosphere is the celestial matter, incomparably more pure, subtile and active than air.
