Erotica (from the Greek ἔρως, eros "desire") is any artistic work that deals substantively with erotically stimulating or sexually arousing subject matter. All forms of art may depict erotic content, including painting, sculpture, photography, drama, film, music or literature. Erotica has high-art aspirations, differentiating it from commercial pornography.
Curiosa is erotica and pornography as discrete, collectible items, usually in published or printed form.
Erotica and pornography 
Distinction is often made between erotica and pornography (as well as the lesser known genre of sexual entertainment, ribaldry), although some viewers may not distinguish between them. Pornography's objective is the graphic depiction of sexually explicit scenes so as to arouse a quick, intense reaction. Additionally, pornography is often described as exploitative or degrading.
