When earth meets with fire and is dissolved by the keenness of it, it would drift about, whether it were dissolved in fire itself, or in some mass of air or water, until the parts of it meeting and again being united became earth once more; for it never could pass into any other kind. But when water is divided by fire or by air, it may be formed again and become one particle of fire and two of air: and the divisions of air may become for every particle broken up two particles of fire. And again when fire is caught in air or in waters or in earth, a little in a great bulk, moving amid a rushing body, and contending with it is vanquished and broken up, two particles of fire combine into one figure of air: and when air is vanquished and broken small, from two whole and one half particle one whole figure of water will be composed. Let us also reckon it once again thus: when any of the other kinds is intercepted in fire and is divided by it through the sharpness of its angles and its sides, if it forms into the shape of fire, it at once ceases from being divided...

Let us assign the figures that have come into being in our theory to fire and earth and water and air. To earth let us give the cubical form; for earth is least mobile of the four and most plastic of bodies: and that substance must possess this nature in the highest degree which has its bases most stable. Now of the triangles which we assumed as our starting-point that with equal sides is more stable than that with unequal; and of the surfaces composed of the two triangles the equilateral quadrangle necessarily is more stable than the equilateral triangle... Now among all these that which has the fewest bases must naturally in all respects be the most cutting and keen of all, and also the most nimble, seeing it is composed of the smallest number of similar parts... Let it be determined then... that the solid body which has taken the form of the pyramid [tetrahedron] is the element and seed of fire; and the second in order of generation let [octahedron] us say to be that of air, and the third [icosahedron] that of water. Now all these bodies we must conceive as being so small that each single body in the several kinds cannot for its smallness be seen by us at all; but when many are heaped together, their united mass is seen...

Time then has come into being along with the universe, that being generated together, together they may be dissolved, should a dissolution of them ever come to pass; and it was made after the pattern of the eternal nature, that it might be as like to it as was possible. For the pattern is existent for all eternity; but the copy has been and is and shall be throughout all time continually. So then this was the plan and intent of God for the generation of time; the sun and the moon and five other stars which have the name of planets have been created for defining and preserving the numbers of time. ...and a month is fulfilled when the moon, after completing her own orbit, overtakes the sun; a year, when the sun has completed his own course. But the courses of the others men have not taken into account, save a few out of many... they do not know that time arises from the wanderings of these, which are incalculable in multitude and marvellously intricate. None the less however can we observe that the perfect number of time fulfils the perfect year at the moment when the relative swiftnesses of all the eight revolutions accomplish their course together and reach their starting-point, being measured by the circle of the same and uniformly moving. In this way then and for these causes were created all such of the stars as wander through the heavens and turn about therein, in order that this universe may be most like to the perfect and ideal animal by its assimilation to the eternal being.

And when the father who begat it perceived the created image of the eternal gods, that it had motion and life, he rejoiced and was well pleased; and he bethought him to make it yet more nearly like its pattern. Now whereas that is a living being eternally existent, even so he essayed to make this All the like to the best of his power. Now so it was that the nature of the ideal was eternal. But to bestow this attribute altogether upon a created thing was impossible; so he bethought him to make a moving image of eternity, and while he was ordering the universe he made of eternity that abides in unity an eternal image moving according to number, even that which we have named time. For whereas days and nights and months and years were not before the universe was created, he then devised the generation of them along with the fashioning of the universe. Now all these are portions of time, and was and shall be are forms of time that have come to be, although we wrongly ascribe them unawares to the eternal essence. For we say that it was and is and shall be, but in verity is alone belongs to it: and was and shall be it is meet should be applied only to Becoming which moves in time; for these are motions. But that which is ever changeless without motion must not become elder or younger in time, neither must it have become so in past nor be so in the future; nor has it to do with any attributes that Becoming attaches to the moving objects of sense: these have come into being as forms of time, which is the image of eternity and revolves according to number. Moreover we say that the become is the become, and the becoming is the becoming, and that which shall become is that which shall become, and not-being is not-being. In all this we speak incorrectly. But concerning these things the present were perchance not the right season to inquire particularly.

So when the universe was quickened with soul, God was well pleased; and he bethought him to make it yet more like its type. And whereas the type is eternal and nought that is created can be eternal, he devised for it a moving image of abiding eternity, which we call time. And he made days and months and years, which are portions of time; and past and future are forms of time, though we wrongly attribute them also to eternity. For of eternal Being we ought not to say 'it was', 'it shall be', but 'it is' alone: and in like manner we are wrong in saying 'it is' of sensible things which become and perish; for these are ever fleeting and changing, having their existence in time.

Now in this island of Atlantis there was a great and wonderful empire which had rule over the whole island and several others, and over parts of the continent and, furthermore, the men of Atlantis had subjected the parts of Libya within the columns of Heracles as far as Egypt, and of Europe as far as Tyrrhenia. This vast power, gathered into one, endeavored to subdue at a blow our country and yours and the whole of the region within the straits, and then, Solon, your country shone forth, in the excellence of her virtue and strength, among all mankind.

At this point one of the priests, a very old man, said, “O Solon, Solon, you Greeks are always children: there is not such a thing as an old Greek.” And on hearing this Solon asked, “What do you mean by this saying?” The priest replied, “You are young in soul, every one of you. For you possess not a single belief that is ancient and derived from old tradition, nor is your understanding grey with age...“

There have been, and will be again, many destructions of mankind arising out of many causes; the greatest have been brought about by the agencies of fire and water, and other lesser ones by innumerable other causes. There is a story, which even you have preserved, that once upon a time Phaethon, the son of Helios, having yoked the steeds in his father's chariot, because he was not able to drive them in the path of his father, burnt up all that was upon the earth, and was himself destroyed by a thunderbolt. Now this has the form of a myth, but really signifies a declination of the bodies moving in the heavens around the earth, and a great conflagration of things upon the earth, which recurs after long intervals; at such times those who live upon the mountains and in dry and lofty places are more liable to destruction than those who dwell by rivers or on the seashore. And from this calamity the Nile, who is our never-failing saviour, delivers and preserves us. When, on the other hand, the gods purge the earth with a deluge of water, the survivors in your country are herdsmen and shepherds who dwell on the mountains, but those who, like you, live in cities are carried by the rivers into the sea. Whereas in this land, neither then nor at any other time, does the water come down from above on the fields, having always a tendency to come up from below; for which reason the traditions preserved here are the most ancient. The fact is, that wherever the extremity of winter frost or of summer sun does not prevent, mankind exist, sometimes in greater, sometimes in lesser numbers. And whatever happened either in your country or in ours, or in any other region of which we are informed—if there were any actions noble or great or in any other way remarkable, they have all been written down by us of old, and are preserved in our temples.

Then we may begin by assuming that there are three classes of men—lovers of wisdom, lovers of honor, lovers of gain?

The inexperienced in wisdom and virtue, ever occupied with feasting and such, are carried downward, and there, as is fitting, they wander their whole life long, neither ever looking upward to the truth above them nor rising toward it, nor tasting pure and lasting pleasures. Like cattle, always looking downward with their heads bent toward the ground and the banquet tables, they feed, fatten, and fornicate. In order to increase their possessions they kick and butt with horns and hoofs of steel and kill each other, insatiable as they are.
