Ovid
The Metamorphoses of Ovid, Book I (Fable. 10)
Deucalion and Pyrrha re-people the earth by casting stones behind them, in the manner prescribed by the Goddess Themis, whose oracle they had consulted.

He thus spoke, and they wept. They resolved to pray to the Deities of Heaven, and to seek relief through the sacred oracles. There is no delay; together they repair to the waters of Cephisus,65 though not yet clear, yet now cutting their wonted channel. Then, when they have sprinkled the waters poured on their clothes66 and their heads, they turn their steps to the temple of the sacred Goddess, the roof of which was defiled with foul moss, and whose altars were standing without fires. Soon as they reached the steps of the temple, each of them fell prostrate on the ground, and, trembling, gave kisses to the cold pavement. And thus they said:

“If the Deities, prevailed upon by just prayers, are to be mollified, if the wrath of the Gods is to be averted; tell us, O Themis, by what art the loss of our race is to be repaired, and give thy assistance, O most gentle Goddess to our ruined fortunes.” The Goddess was moved, and gave this response: “Depart from my temple, and cover your heads,67 and loosen the garments girt around you, and throw behind your backs the bones of your great mother.” For a long time they are amazed; and Pyrrha is the first by her words to break the silence, and then refuses to obey the commands of the Goddess; and begs her, with trembling lips, to grant her pardon, and dreads to offend the shades of her mother by casting her bones. In the meantime they reconsider the words of the response given, but involved in dark obscurity, and they ponder them among themselves. Upon that, the son of Prometheus soothes the daughter of Epimetheus with these gentle words, and says, “Either is my discernment fallacious, or the oracles are just, and advise no sacrilege. The earth is the great mother; I suspect that the stones in the body of the earth are the bones meant; these we are ordered to throw behind our backs.” Although she, descended from Titan,68 is moved by this interpretation of her husband, still her hope is involved in doubt; so much do they both distrust the advice of heaven; but what harm will it do to try?

They go down, and they veil their heads, and ungird their garments, and cast stones, as ordered, behind their footsteps. The stones (who could have believed it, but that antiquity is a witness of the thing?) began to lay aside their hardness and their stiffness, and by degrees to become soft; and when softened, to assume a new form. Presently after, when they were grown larger, a milder nature, too, was conferred on them, so that some shape of man might be seen in them, yet though but imperfect; and as if from the marble commenced to be wrought, not sufficiently distinct, and very like to rough statues. Yet that part of them which was humid with any moisture, and earthy, was turned into portions adapted for the use of the body. That which is solid, and cannot be bent, is changed into bones; that which was just now a vein, still remains under the same name.69 And in a little time, by the interposition of the Gods above, the stones thrown by the hands of the man, took the shape of a man, and the female race was renewed by the throwing of the woman. Thence are we a hardy generation, and able to endure fatigue, and we give proofs from what original we are sprung.

66. Poured on their clothes.]—Ver. 371. It was the custom of the ancients, before entering a temple, either to sprinkle themselves with water, or to wash the body all over.

67. Cover your heads.]—Ver. 382. It was a custom among the ancients to cover their heads in sacrifice and other acts of worship, either as a mark of humility, or, according to Plutarch, that nothing of ill omen might meet their sight, and thereby interrupt the performance of the rites.

68. Descended from Titan.]—Ver. 395. Pyrrha was of the race of the Titans; for Iapetus, her grandfather, was the son of Titan and Terra.

69. Under the same name.]—Ver. 410. With his usual propensity for punning, he alludes to the use of the word ‘vena,’ as signifying either ‘a vein’ of the body, or a ‘streak’ or ‘vein’ in stone, according to the context.
