In medieval legend, a succubus (plural succubi; from Latinsuccuba; "prostitute") is a female demon that seduces men (especially monks) in dreams tohave sexual intercourse. They draw energy from the men to sustain themselves, often untilthe point of exhaustion or death of the victim. From mythology and fantasy, Lilith andthe Lilin (Jewish), Lilitu (Sumerian) and Rusalka (Slavic) were succubi.
According to the Malleus Maleficarum, or "Witches' Hammer", succubi would collectsemen from the men they slept with, which incubi would then use to impregnate women.Children so begotten were supposed to be more susceptible to the influence of demons.
Honoré de Balzac wrote a short story The Succubus concerning a 1271 trial ofa she-devil succubus in the guise of a woman, who amongst other things could use her hairto entangle victims.
From the 16th century, the carving of a succubus on theoutside of an inn indicated that the establishment also operated as a brothel.
