1 Enoch 8:1-2
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 . . .
Commodianus On Christian Discipline 3
When Almighty God, to beautify the nature of the world, willed that that earth should be visited by angels, when they were sent down they despised His laws. Such was the beauty of women, that it turned them aside; so that, being contaminated, they could not return to heaven. Rebels from God, they uttered words against Him. Then the Highest uttered His judgment against them; and from their seed giants are said to have been born. By them arts were made known in the earth, and they taught the dyeing of wool, and everything which is done; and to them, when they died, men erected images. But the Almighty, because they were of an evil seed, did not approve that, when dead, they should be brought back from death. Whence wandering they now subvert many bodies, and it is such as these especially that you this day worship and pray to as gods.
