Large phalli were often used near entryways, for the phallus was a good-luck charm, and the carvings were common in homes.
One of the first objects excavated when the complex was discovered was a marble statue showing the god Pan having sex with a goat, a detailed depiction of bestiality considered so obscene that it was not on public display until the year 2000 and remains in the Secret Museum, Naples.
Obscenity is the judicially recognized exception to the first amendment.
Historically, this exception was used in an attempt to ban information about sex education, studies on nudism, and sexually explicit literature.
On the other hand, graphic paintings in a brothel advertise sexual services in murals above each door.
In Pompeii, phalli and testicles engraved in the sidewalks were created to aid visitors in finding their way by pointing to the prostitution and entertainment district as well as general decoration.
They have been created by nearly every civilization, ancient and modern.Some of the more common images are of animals, hunting scenes and depictions of human genitalia.Nude human beings with exaggerated sexual characteristics are depicted in some Paleolithic paintings and artifacts (e.g. Recently discovered cave art at Creswell Crags in England, thought to be more than 12,000 years old, includes some symbols that may be stylized versions of female genitalia.There are numerous sexually explicit paintings and sculptures from the ruined Roman buildings in Pompeii and Herculaneum but the original purposes of the depictions can vary.On one hand, in the Villa of the Mysteries, there is a ritual flagellation scene that is clearly associated with a religious cult and this image can be seen as having religious significance rather than sexual.
