STRANGER: Let us now reflect and try to gather from what has been said the nature of the phenomenon which we affirmed to be the cause of all these wonders. It is this. YOUNG SOCRATES: What? STRANGER: The reversal which takes place from time to time of the motion of the universe. YOUNG SOCRATES: How is that the cause? STRANGER: Of all changes of the heavenly motions, we may consider this to be the greatest and most complete. YOUNG SOCRATES: I should imagine so. STRANGER: And it may be supposed to result in the greatest changes to the human beings who are the inhabitants of the world at the time. YOUNG SOCRATES: Such changes would naturally occur. STRANGER: And animals, as we know, survive with difficulty great and serious changes of many different kinds when they come upon them at once. YOUNG SOCRATES: Very true. STRANGER: Hence there necessarily occurs a great destruction of them, which extends also to the life of man; few survivors of the race are left, and those who remain become the subjects of several novel and remarkable phenomena, and of one in particular, which takes place at the time when the transition is made to the cycle opposite to that in which we are now living. YOUNG SOCRATES: What is it? STRANGER: The life of all animals first came to a standstill, and the mortal nature ceased to be or look older, and was then reversed and grew young and delicate; the white locks of the aged darkened again, and the cheeks the bearded man became smooth, and recovered their former bloom; the bodies of youths in their prime grew softer and smaller, continually by day and night returning and becoming assimilated to the nature of a newly-born child in mind as well as body; in the succeeding stage they wasted away and wholly disappeared. And the bodies of those who died by violence at that time quickly passed through the like changes, and in a few days were no more seen. YOUNG SOCRATES: Then how, Stranger, were the animals created in those days; and in what way were they begotten of one another?
