Here let us sum up:—The science of pure knowledge had a part which was the science of command, and this had a part which was a science of wholesale command; and this was divided into the management of animals, and was again parted off into the management of herds of animals, and again of land animals, and these into hornless, and these into bipeds; and so at last we arrived at man, and found the political and royal science. And yet we have not clearly distinguished the political shepherd from his rivals. No one would think of usurping the prerogatives of the ordinary shepherd, who on all hands is admitted to be the trainer, matchmaker, doctor, musician of his flock. But the royal shepherd has numberless competitors, from whom he must be distinguished; there are merchants, husbandmen, physicians, who will all dispute his right to manage the flock. I think that we can best distinguish him by having recourse to a famous old tradition, which may amuse as well as instruct us; the narrative is perfectly true, although the scepticism of mankind is prone to doubt the tales of old. You have heard what happened in the quarrel of Atreus and Thyestes? “You mean about the golden lamb?” No, not that; but another part of the story, which tells how the sun and stars once arose in the west and set in the east, and that the god reversed their motion, as a witness to the right of Atreus. “There is such a story.” And no doubt you have heard of the empire of Cronos, and of the earthborn men? The origin of these and the like stories is to be found in the tale which I am about to narrate.
There was a time when God directed the revolutions of the world, but at the completion of a certain cycle he let go; and the world, by a necessity of its nature, turned back, and went round the other way. For divine things alone are unchangeable; but the earth and heavens, although endowed with many glories, have a body, and are therefore liable to perturbation. In the case of the world, the perturbation is very slight, and amounts only to a reversal of motion. For the lord of moving things is alone self-moved; neither can piety allow that he goes at one time in one direction and at another time in another; or that God has given the universe opposite motions; or that there are two gods, one turning it in one direction, another in another. But the truth is, that there are two cycles of the world, and in one of them it is governed by an immediate Providence, and receives life and immortality, and in the other is let go again, and has a reverse action during infinite ages. This new action is spontaneous, and is due to exquisite perfection of balance, to the vast size of the universe, and to the smallness of the pivot upon which it turns. All changes in the heaven affect the animal world, and this being the greatest of them, is most destructive to men and animals. At the beginning of the cycle before our own very few of them had survived; and on these a mighty change passed. For their life was reversed like the motion of the world, and first of all coming to a stand then quickly returned to youth and beauty. The white locks of the aged became black; the cheeks of the bearded man were restored to their youth and fineness; the young men grew softer and smaller, and, being reduced to the condition of children in mind as well as body, began to vanish away; and the bodies of those who had died by violence, in a few moments underwent a parallel change and disappeared. In that cycle of existence there was no such thing as the procreation of animals from one another, but they were born of the earth, and of this our ancestors, who came into being immediately after the end of the last cycle and at the beginning of this, have preserved the recollection. Such traditions are often now unduly discredited, and yet they may be proved by internal evidence. For observe how consistent the narrative is; as the old returned to youth, so the dead returned to life; the wheel of their existence having been reversed, they rose again from the earth: a few only were reserved by God for another destiny. Such was the origin of the earthborn men.
“And is this cycle, of which you are speaking, the reign of Cronos, or our present state of existence?” No, Socrates, that blessed and spontaneous life belongs not to this, but to the previous state, in which God was the governor of the whole world, and other gods subject to him ruled over parts of the world, as is still the case in certain places. They were shepherds of men and animals, each of them sufficing for those of whom he had the care. And there was no violence among them, or war, or devouring of one another. Their life was spontaneous, because in those days God ruled over man; and he was to man what man is
