1 Enoch 8:1

1 And Azâzêl taught men to make swords, and knives, and shields, and breastplates, and made known to them the metals 〈of the earth〉 and the art of working them, and bracelets, and ornaments, and the use of antimony, and the beautifying of the eyelids, and all kinds of costly stones, and all colouring tinctures. 2 And there arose much godlessness, and they committed fornication, and they were led astray, and became corrupt in all their ways. Semjâzâ taught enchantments, and root-cuttings, Armârôs the resolving of enchantments, Barâqîjâl, (taught) astrology, Kôkabêl the constellations, Ezêqêêl the knowledge of the clouds, 〈Araqiêl the signs of the earth, Shamsiêl the signs of the sun〉, and Sariêl the course of the moon. And as men perished, they cried, and their cry went up to heaven . . .

Pirkei DeRabbi Eliezer 22:4

Rabbi Simeon said: From Seth arose and were descended all the generations of the righteous. From Cain arose and were descended all the generations of the wicked, who rebel and sin, who rebelled against their Rock, and they said: We do not need the drops of Thy rain, neither to walk in Thy ways, as it is said, "Yet they said unto God, Depart from us" (Job 21:14). Rabbi Meir said: || The generations of Cain went about stark naked, men and women, just like the beasts, and they defiled themselves with all kinds of immorality, a man with his mother or his daughter, or the wife of his brother, or the wife of his neighbour, in public and in the streets, with evil inclination which is in the thought of their heart, as it is said, "And the Lord saw that the wickedness of man was great in the earth" (Gen. 6:5). Rabbi said: The angels who fell from their holy place in heaven saw the daughters of the generations of Cain walking about naked, with their eyes painted like harlots, and they went astray after them, and took wives from amongst them, as it is said, "And the sons of Elohim saw the daughters of men that they were fair; and they took them wives of all that they chose" (Gen. 6:2). Rabbi Joshua said: The angels are flaming fire, as it is said, "His servants are a flaming fire" (Ps. 104:4), and fire came with the coition of flesh and blood, but did not burn the body; but when they fell from heaven, from their holy place, their strength and stature (became) like that of the sons of men, and their frame was (made of) clods of dust, as it is said, "My flesh is clothed with worms and clods of dust" (Job 7:5).
