21 But perhaps this foul pollution may be less apparent in the rest. Did, then, the ruler of the heavens, the father of gods and men, who, by the motion of his eyebrow, and by his nod, shakes the whole heavens and makes them tremble—did he find his origin in man and woman? And unless both sexes abandoned themselves to degrading pleasures in sensual embraces, would there be no Jupiter, greatest of all; and even to this time would the divinities have no king, and heaven stand without its lord?
And why do we marvel that you say Jove sprang from a woman's womb, seeing that your authors relate that he both had a nurse, and in the next place maintained the life given to him by nourishment drawn from a foreign breast? What say you, O men? Did, then, shall I repeat, the god who makes the thunder crash, lightens and hurls the thunderbolt, and draws together terrible clouds, drink in the streams of the breast, wail as an infant, creep about, and, that he might be persuaded to cease his crying most foolishly protracted, was he made silent by the noise of rattles, and put to sleep lying in a very soft cradle, and lulled with broken words?
O devout assertion of the existence of gods, pointing out and declaring the venerable majesty of their awful grandeur! Is it thus in your opinion, ask, that the exalted powers of heaven are produced? Do your gods come forth to the light by modes of birth such as these, by which asses, pigs. dogs, by which the whole of this unclean herd of earthly beasts is conceived and begotten?
