Succubus

Succubus is a female demon traditionally imagined as taking life-force from men through sexual contact, rather than by drinking blood. The figure makes desire itself a mode of predation: the victim’s physical strength and health are depleted, while supernatural compulsion can turn an unwanted encounter into a story that appears to excuse or displace responsibility. In the book’s account, the Succubus belongs not to one fixed creature-type but to a long, shifting family of seductive predators whose forms overlap with those of vampires, demons, and revenants.

Identity and Ancient Roots

The Succubus is presented as the female counterpart to the Incubus, but the distinction does not make the pair simple opposites. Their shared operation is the theft of vitality through sexual contact, an alternative to the vampire’s more familiar act of taking blood. The source links this family of beings to tales of unseen nocturnal assault and to a recurring idea: bodily weakness or unexpected pregnancy can be attributed to an external supernatural agent. Across centuries, the demons’ appearance becomes more attractive, making the threat at once more seductive and more difficult to distinguish from desire freely chosen.

An early parallel appears in the account of Lamia. In Greek myth, after Zeus’s infidelity with Lamia, Hera kills Lamia’s children, or compels Lamia to kill them herself, and condemns her to insomnia. Zeus gives Lamia the ability to remove her eyes so she can rest; she later takes revenge on humanity by sucking the blood of sleeping children. Over time, Lamia changes in the stories: from a bereaved, blood-drinking figure she becomes a deadly seductress who lures and devours young men, resembling a Succubus. This transformation shows how the boundaries between blood-drinker and sexual demon could shift without the underlying image of predatory intimacy disappearing.

Sexual Predation and the Loss of Agency

Tales of the Incubus and Succubus make sexual contact a means of draining health, whether or not blood is taken. The encounters are often described as enjoyable for the victim, a feature that complicates their violence: pleasure can coexist with an inability to refuse. In the book’s analysis, the supernatural attacker serves as an explanation for experiences that would otherwise be difficult to name, including sexual violation and physical decline. The demon’s power offers a scapegoat for moral and bodily consequences, but that same explanation can blur the victim’s agency by making coercion appear to absolve them of responsibility for what happened.

The female demon, in particular, is described as taking men’s purity and physical strength while they sleep. The account traces this pattern to the Lilitu, characterized as a demon who lies upon sleeping men to satisfy her desire and leaves them weakened. The related figure of Lilu appears in an ancient Mesopotamian tradition: a faceless demon that attacks women through their dreams. These figures vary in gender and form, but share a nocturnal assault on the sleeping body. Their stories make sleep a vulnerable threshold, where an encounter can be experienced as both intimate and imposed.

Demonology, Sex, and the Corpse

In 1597, King James VI and I addressed the mechanics of demonic impregnation in Daemonologie. His discussion considers two possible means: a demon might take sperm from a living man and convey it to a woman, or might borrow a dead body and use it visibly as a man. The reasoning turns on the supposed coldness of the sperm after such transfer or contact with a corpse. The book summarizes the implication as a demon needing to be both male and female, able to change biological sex in order to take sperm from a man and transfer it to a woman.

This argument is relevant to the development of vampire lore because demons were also believed capable of possessing a corpse and wearing it as a kind of costume. In that conception, the dead body is not simply a returning person: it can be an instrument through which a supernatural being walks among the living and seduces them. The source describes this as part of a gradual separation between the revenant and the vampire, even as the idea of an undead seducer helps prepare the ground for later vampire mythology. The Succubus therefore occupies a conceptual borderland: its defining act is sexual predation, but the stories around it touch the same questions of bodily invasion, death, and apparent return that shape accounts of the undead.

Folkloric Variants and the Seductive Stranger

The book places the Succubus within a broader, geographically varied tradition of supernatural seducers. The Hungarian Lidérc may appear to a lonely woman as a lost loved one, visit her repeatedly at night, and gradually drain her blood until she wastes away. It can also take the form of a Csodacsirke, or miracle chicken, which hatches in a human armpit and must be kept occupied lest it damage the house. The Trauco, from Chile’s Chiloé Province, is described instead as a sexually powerful forest creature whose advances no attractive young woman can resist; its potency becomes an explanation for unexpected pregnancy. These beings are not presented as interchangeable with the Succubus, but their stories share the figure of a supernatural visitor whose apparent allure conceals the removal of choice or vitality.

Scottish tales of the Baobhan Sith offer another close comparison. In one story, four men shelter in a shieling after hunting. They sing and dance, and the dancers wish aloud for partners. Four women enter; three dance with the men, while the fourth sits with the singer. One man notices blood dripping from his companions and escapes. His pursuer becomes powerless when he reaches a nearby field of horses; at daylight he returns to find the others dead, their blood drained. A second tale relocates the encounter to a cave. The hunters wish for their sweethearts, except Macphee, who says he is glad his wife is at home. The women attack, but Macphee’s dog drives them away and fights off a great hand reaching into the cave. The differing details—an uttered wish, a companion’s warning, the horse field, the dog—organize the same danger around desire and the means of escape. The Baobhan Sith are described as sometimes fairy-like, yet their seductive violence recalls the Succubus tradition.

Cultural Function and Significance

Across the examples, supernatural seducers give form to fears and explanations that move between sex, illness, and death. The book notes that people have repeatedly used such beings as scapegoats for moral and physical troubles. Their stories also make coercion narratively legible: a person may be represented as drawn to an encounter and horrified by it afterward, with supernatural influence accounting for the apparent contradiction. That structure can dramatize the loss of agency, even as it risks reducing the victim’s experience to a convenient explanation.

The Succubus is significant to vampire history less as a stable species than as part of a changing vocabulary of predation. Lamia’s evolution from child-killing blood-drinker to seductive devourer, the demon’s imagined use of a corpse, and the many local variations on nocturnal assault show how readily blood, sex, and death could meet in folklore. The vampire and the Succubus remain distinguishable in their characteristic methods, but their shared imagery—an alluring or uncanny presence that feeds on the living—helps explain why traditions of erotic demons could contribute to the foundations of later undead mythology.
