In ancient folklore traced back to medieval legend, a “succubus” is an enticing female or supernatural female entity that appears in dreams, who takes the form of a attractive human woman in order to seduce men, usually through sexual intercourse. Religious traditions hold that regular sexual encounters with a succubus may result in the deterioration of the man’s health or even his death. In modern fictional representations, a succubus may or may not appear in dreams and is often depicted as a highly voluptuous seductress or enchantress; whereas, in the past, succubi were generally depicted as frightening and demonic. The word is derived from Late Latin succuba “strumpet” (from succubare “to lie under,” from sub- “under” and cubare “to lie”), used to describe the supernatural being as well. The word is first attested from 1387. And there is the short, Saturday morning version, history lesson boys and girls.
