10 But you will perhaps say the human race shuns and execrates such unions; among the gods there is no incest. And why, then, did his mother resist with the greatest vehemence her son when he offered her violence? Why did she flee from his embraces, as if she were avoiding unlawful approaches? For if there was nothing wrong in so doing, she should have gratified him without any reluctance, just as he eagerly wished to satisfy the cravings of his lust. And here, indeed, very thrifty men, and frugal even about shameful works, that that sacred seed may not seem to have been poured forth in vain— the rock, one says, drank up Jupiter's foul incontinence.
What followed next, I ask? Tell. In the very heart of the rock, and in that flinty hardness, a child was formed and quickened to be the offspring of great Jupiter. It is not easy to object to conceptions so unnatural and so wonderful. For as the human race is said by you to have sprung and proceeded from stones, it must be believed that the stones both had genital parts, and drank in the seed cast on them, and when their time was full were pregnant, and at last brought forth, travailing in distress as women do.
That impels our curiosity to inquire, since you say that the birth occurred after ten months, in what womb of the rock was he enclosed at that time? With what food, with what juices, was he supplied? Or what could he have drawn to support him from the hard stone, as unborn infants usually receive from their mothers! He had not yet reached the light, my informant says; and already bellowing and imitating his father's thunderings, he reproduced their sound. And after it was given him to see the sky and the light of day, attacking all things which lay in his way, he made havoc of them, and assured himself that he was able to thrust down from heaven the gods themselves.
O cautious and foreseeing mother of the gods, who, that she might not undergo the ill-will of so arrogant a son, or that his bellowing while still unborn might not disturb her slumbers or break her repose, withdrew herself, and sent far from her that most hurtful seed, and gave it to the rough rock.
