"This earth and the whole region here are decayed and corroded, as things in the sea by the saltness; for nothing of any value grows in the sea, nor, in a word, does it contain anything perfect, but there are caverns, and sand, and mud in abundance, and filth in whatever parts of the sea there is earth, nor are they at all worthy to be compared with the beautiful things with us. But, on the other hand, those things in the upper regions of the earth would appear far more to excel the things with us. For, if we may tell a beautiful fable, it is well worth hearing, Simmias, what kind the things are on the earth beneath the heavens."
"Indeed, Socrates," said Simmias, "we should be very glad to hear that fable."
"First of all, then, my friend," he continued, "this earth, if anyone should survey it from above, is said to have the appearance of balls covered with twelve different pieces of leather, variegated and distinguished with colors, of which the colors found here, and which painters use, are as it were copies. But there the whole earth is composed of such, and far more brilliant and pure than these; for one part of it is purple, and of wonderful beauty, part of a golden color, and part of white, more white than chalk or snow, and in like manner composed of other colors, and those more in number and more beautiful than any we have ever beheld. And those very hollow parts of the earth, though filled with water and air, exhibit a certain species of color, shining among the variety of other colors, so that one continually variegated aspect presents itself to the view. In this earth, being such, all things that grow grow in a manner proportioned to its nature—trees, flowers, and fruits; and again, in like manner, its mountains and stones possess, in the same proportion, smoothness and transparency and more beautiful colors; of which the well-known stones here that are so highly prized are but fragments, such as sardin-stones, jaspers, and emeralds, and all of that kind. But there, there is nothing subsists that is not of this character, and even more beautiful than these.
"But the reason of this is, because the stones there are pure, and not eaten up and decayed, like those here, by rottenness and saltness, which flow down hither together, and which produce deformity and disease in the stones and the earth, and in other things, even animals and plants. But that earth is adorned with all these, and moreover with gold and silver, and other things of the kind: for they are naturally conspicuous, being numerous and large, and in all parts of the earth; so that to behold it is a sight for the blessed. There are also many other animals and men upon it, some dwelling in mid-earth, others about the air, as we do about the sea, and others in islands which the air flows round, and which are near the continent: and in one word, what water and the sea are to us for our necessities, the air is to them; and what air is to us, that ether is to them.
"But their seasons are of such a temperament that they are free from disease, and live for a much longer time than those here, and surpass us in sight, hearing, and smelling, and everything of this kind, as much as air excels water, and ether air, in purity. Moreover, they have abodes and temples of the gods, in which gods really dwell, and voices and oracles, and sensible visions of the gods, and such-like intercourse with them; the sun, too, and moon, and stars, are seen by them such as they really are, and their felicity in other respects is correspondent with these things.
"And such, indeed, is the nature of the whole earth and the parts about the earth; but there are many places all round it throughout its cavities, some deeper and more open than that in which we dwell: but others that are deeper have less chasm than in our region, and other are shallower in depth than they are here, and broader.
"But all these are in many places perforated one into another under the earth, some with narrower and some with wider channels, and have passages through, by which a great quantity of water flows from one into another, as into basins, and there are immense bulks of ever-flowing rivers under the earth, both of hot and cold water, and a great quantity of fire, and mighty rivers of fire, and many of liquid mire, some purer and some more miry, as in Sicily there are rivers of mud that flow before the lava, and the lava itself, and from these the several places are filled, according as the overflow from time to time happens to come to each of them. But all these move up and down as it were by a certain oscillation existing in the earth. And this oscillation proceeds from such natural cause as this: one of the chasms of the earth is exceedingly large, and perforated through the entire earth, and is that which Homer[[43]] speaks of, 'very far off, where is the most profound abyss beneath the earth,' which elsewhere both he and many other poets have called Tartarus. For into this chasm all rivers flow together, and from it flow out again, but they severally derive their character from the earth through which they flow."
[!-- Note Anchor 43 --][Footnote 43: Iliad, lib. viii., v. 14.]
"And the reason why all streams flow out from thence and flow into it is because this liquid has neither bottom nor base. Therefore it oscillates and fluctuates up and down, and the air and the wind around it do the same; for they accompany it, both when it rushes to those parts of the earth, and when to these. And as in respiration the flowing breath is continually breathed out and drawn in, so there the wind, oscillating with the liquid, causes certain vehement and irresistible winds both as it enters and goes out. When, therefore, the water rushing in descends to the place which we call the lower region, it flows through the earth into the streams there and fills them, just as men pump up water. But when again it leaves those regions and rushes hither, it again fills the rivers here, and these, when filled, flow through channels and through the earth, and having severally reached the several places to which they are journeying, they make seas, lakes, rivers, and fountains.
"Then sinking again from thence beneath the earth, some of them having gone round longer and more numerous places, and others round fewer and shorter, they again discharge themselves into Tartarus, some much lower than they were drawn up, others only a little so, but all of them flow in again beneath the point at which they flowed out. And some issue out directly opposite the place by which they flow in, others on the same side: there are also some which having gone round altogether in a circle, folding themselves once or several times round the earth, like serpents, when they had descended as low as possible, discharge themselves again; and it is possible for them to descend on either side as far as the middle, but not beyond; for in each direction there is an acclivity to the streams both ways.
