A femme fatale, sometimes called a maneater, Mata Hari, or vamp, is a stock character of a mysterious, beautiful, and seductive woman whose charms ensnare her lovers, often leading them into compromising, deadly traps. She is an archetype of literature and art. Her ability to enchant, entice and hypnotize her victim with a spell was in the earliest stories seen as verging on supernatural; hence, the femme fatale today is still often described as having a power akin to an enchantress, seductress, witch, having power over men. Femmes fatales are typically villainous, or at least morally ambiguous, and always associated with a sense of mystification, and unease.

Delilah is a woman mentioned in the sixteenth chapter of the Book of Judges in the Hebrew Bible. She is loved by Samson, a Nazirite who possesses great strength and serves as the final Judge of Israel. Delilah is bribed by the lords of the Philistines to discover the source of his strength. After three failed attempts at doing so, she finally goads Samson into telling her that his vigor is derived from his hair. As he sleeps, Delilah cuts Samson's hair, thereby enabling her to turn him over to the Philistines.
