pornographic

1857, "description of prostitutes," from Fr. pornographie, from Gk. pornographos "(one) writing of prostitutes," from porne "prostitute," originally "bought, purchased" (with an original notion, probably of "female slave sold for prostitution;" related to pernanai "to sell," from PIE root per- "to traffic in, to sell," cf. L. pretium "price") + graphein "to write." Originally used of classical art and writing; application to modern examples began 1880s. Main modern meaning "salacious writing or pictures" represents a slight shift from the etymology, though classical depictions of prostitution usually had this quality. Pornographer is earliest form of the word, attested from 1850. Pornocracy (1860) is "the dominating influence of harlots," used specifically of the government of Rome during the first half of the 10th century by Theodora and her daughters.
