In Greek mythology, Lamia was a beautiful woman who, like so many other beautiful Greek women, got it on with Zeus and bore a number of his children. Zeus' wife, Hera, was jealous (because Hera was nearly always jealous), and she kidnapped all the children to keep them out of their mother's arms.

Mad with grief, Lamia began to entice mortal children to serve as her substitute kids. However, her deceitful actions caused her to transform into a monster with the head and breasts of a woman and the body of a giant serpent, and rather than treating the children as her own children, she began to treat them as her own supper, devouring them with gusto.

In time, Lamia was able to reproduce, giving life to creatures like herself. The lamiae had the power to seduce men and suck out their life force.
