The history of erotic depictions includes paintings, sculpture, photographs, dramatic arts, music and writings that show scenes of a sexual nature throughout time. They have been created by nearly every civilization, ancient and modern. Early cultures often associated the sexual act with supernatural forces and thus their religion is intertwined with such depictions. In Asian countries such as India, Nepal, Sri Lanka, Japan and China, representations of sex and erotic art have specific spiritual meanings within native religions. The ancient Greeks and Romans produced much art and decoration of an erotic nature, much of it integrated with their religious beliefs and cultural practices.
