Erotica or "curiosa," are works of art, including literature, photography, film, sculpture and painting, that deal substantively with erotically stimulating or sexually arousing descriptions. Erotica is a modern word used to describe the portrayal of the human anatomy and sexuality with high-art aspirations, differentiating such work from commercial pornography.
