Plato, Symposium

[190a] on a cylindrical neck. There was one head to the two faces, which looked opposite ways; there were four ears, two privy members, and all the other parts, as may be imagined, in proportion. The creature walked upright as now, in either direction as it pleased and whenever it started running fast, it went like our acrobats, whirling over and over with legs stuck out straight; only then they had eight limbs to support and speed them [190b] swiftly round and round. The number and features of these three sexes were owing to the fact that the male was originally the offspring of the sun, and the female of the earth; while that which partook of both sexes was born of the moon, for the moon also partakes of both.¹ They were globular in their shape as in their progress, since they took after their parents. Now, they were of surprising strength and vigor, and so lofty in their notions that they even conspired against the gods; and the same story is told of them as Homer relates of [190c] Ephialtes and Otus,² that scheming to assault the gods in fight they essayed to mount high heaven.

“Thereat Zeus and the other gods debated what they should do, and were perplexed: for they felt they could not slay them like the Giants, whom they had abolished root and branch with strokes of thunder—it would be only abolishing the honors and observances they had from men; nor yet could they endure such sinful rioting. Then Zeus, putting all his wits together, spoke at length and said: ‘Methinks I can contrive that men, without ceasing to exist, shall give over their iniquity through a lessening of their strength. [190d] I propose now to slice every one of them in two, so that while making them weaker we shall find them more useful by reason of their multiplication; and they shall walk erect upon two legs. If they continue turbulent and do not choose to keep quiet, I will do it again,’ said he; ‘I will slice every person in two, and then they must go their ways on one leg, hopping.’ So saying, he sliced each human being in two, just as they slice sorb-apples to make a dry preserve, or eggs with hairs; [190e] and at the cleaving of each he bade Apollo turn its face and half-neck to the section side, in order that every one might be made more orderly by the sight of the knife's work upon him; this done, the god was to heal them up. Then Apollo turned their faces about, and pulled their skin together from the edges over what is now called the belly, just like purses which you draw close with a string; the little opening he tied up in the middle of the belly, so making what we know as the navel.
