The term erotic literature encompasses fictional and factual stories and accounts of eros (passionate, romantic, or sexual relationships) intended to arouse erotic feelings in readers. This may overlap yet also contrast with erotica, which focuses more specifically on sexual feelings. Other common elements are satire and social criticism. Much erotic literature features erotic art to illustrate the text.
Although cultural disapproval of erotic literature has always existed, its circulation was not seen as a major problem before the invention of printing, as the costs of producing individual manuscripts limited distribution to a very small group of wealthy and literate readers. The invention of printing, in the 15th century, brought with it both a greater market and increasing restrictions, including censorship and legal restraints on publication on the grounds of obscenity. Because of this, much of the production of this type of material became clandestine.
