How Vampires Work

The vampires in contemporary books, movies and television shows are incredibly elaborate creatures. According to the predominant mythology, every vampire was once a human, who, after being bitten by a vampire, died and rose from the grave as a monster.

Vampires crave the human blood and hunt humans during the night. They use their protruding fangs to puncture their victims' necks.

Since they're reanimated corpses — the living remains of a deceased person — vampires are often referred to as "the undead." According to legends, the blood-drinking beings can still pass as healthy humans, however, and will walk undetected among the living. In fact, vampires may be attractive, highly sexual beings, seducing their prey before feeding. A vampire may also take the form of an animal, usually a bat or wolf, in order to sneak up on a victim.

Vampires are potentially immortal, but they do have a few weaknesses. Killing vampires can typically be achieved with a stake through the heart, fire, beheading or direct sunlight. Vampires are canonically wary of crucifixes, holy water and garlic. They don't cast a reflection, and they have superhuman strength.

These vampire beliefs, with their particular combination of characteristics and governing rules, are actually a fairly recent invention. Bram Stoker conceived the lore in his 1897 novel "Dracula." Other authors reinterpreted Dracula in a number of plays, movies and books.

But while the specifics are new, most of the individual elements of the legend have deep roots, spanning many regions and cultures. In the next few sections, we'll look at some of the more notable vampire ancestors.

The Legends of Lamastu

Nobody knows when people came up with the first vampiric figures, but the legends date back at least 4,000 years, to the ancient Assyrians and Babylonians of Mesopotamia.

Mesopotamians feared Lamastu (also spelled Lamashtu), a vicious demon goddess who preyed on humans. In Assyrian legend, Lamastu, the daughter of sky god Anu, would creep into a house at night and steal or kill babies, either in their cribs or in the womb. Believers attributed sudden infant death syndrome and miscarriage to this figure.

Lamastu, which translates to "she who erases," would also prey on adults, sucking blood from young men and bringing disease, sterility and nightmares. She is often depicted with wings and birdlike talons, and sometimes with the head of a lion.

To protect themselves from Lamastu, pregnant women would wear amulets depicting Pazuzu, another evil god who once defeated the demoness.

Lilith: From Eden to Demoness

Lamastu is closely associated with Lilith, a prominent figure in some Jewish texts. Accounts of Lilith vary considerably, but in the most notable versions of the story, she was the original woman. God created both Adam and Lilith from the Earth, but there was soon trouble between them. Lilith refused to take a subservient position to Adam, since she came from the same place he did.

In one ancient version of the legend, Lilith left Eden and began birthing her own children. God sent three angels to bring her back, and when she refused, they promised they would kill 100 of her children every day until she returned. Lilith in turn vowed to destroy human children.

Accounts of Lilith as a child-killer seem to be taken directly from the Lamastu legend. She is often described as a winged demoness with sharp talons, who came in the night, primarily to steal away infants and fetuses. Most likely, the Jews assimilated the figure of Lamastu into their tradition, but it's also possible that both myths were inspired by a third figure.

While she is often depicted as a terrifying creature, Lilith also had seductive qualities. The ancient Jews believed she would come to men at night as a succubus.

Greek and Celtic Nightmares

The ancient Greeks feared similar creatures, notably Lamia, a demoness with the head and torso of a woman and the lower body of a snake.

In one version of the legend, Lamia was one of Zeus' mortal lovers. Filled with anger and jealousy, Zeus' wife, the goddess Hera, made Lamia insane so she would eat all her children. Once Lamia realized what she had done, she became so angry that she turned into an immortal monster, sucking the blood from young children out of jealousy for their mothers.

The Greeks also feared the empusai, the malicious daughters of Hecate, the goddess of witchcraft. The empusai, who could change form, came up from Hades (the underworld) at night as beautiful women. They would seduce shepherds in the field, and then devour them.

A similar creature, the baobhan sith, shows up in Celtic folklore.

Asian Myths and the Evolution of Vampire Legends

Vampire-like figures also have a long history in the mythology of Asia. Indian folklore describes a number of nightmarish characters, including rakshasa, gargoyle-like shape-shifters who preyed on children, and vetala, demons who would take possession of recently dead bodies to wreak havoc on the living.

In Chinese folklore, corpses could sometimes rise from the grave and walk again. These k'uei were created when a person's p'o (lower spirit) did not pass onto the afterlife at death, usually because of bad deeds during life. The p'o, angered by its horrible fate, would reanimate the body and attack the living at night.

One particularly vicious sort of k'uei, known as the Kuang-shi (or Chiang-shi), could fly and take different forms. The Kuang-shi was covered in white fur, had glowing red eyes and bit into its prey with sharp fangs.

Nomadic tribes and traveling traders spread different vampire legends throughout Asia, Europe and the Middle East. As these stories traveled, their various elements combined to form new vampire myths. In the past 1,000 years, vampire legends have been especially pervasive of eastern European contributions.

Eastern European Vampire Folklore

Eastern European folklore directly inspired the Dracula legend and the modern vampire belief system that came out of it. History records dozens of mythical vampire figures in this region, going back hundreds of years. These vampires all have their particular habits and characteristics, but most fall into one of two general categories:

The most notable demon vampires were the Russian upir and the Greek vrykolakas. In these traditions, sinners, unbaptized babies and other people outside the Christian faith were more likely to be reanimated after death. Those who practiced witchcraft were particularly susceptible because they had already given their soul to the devil in life. Once the undead corpses rose from the grave, they would terrorize the community, feeding on the living.

By many accounts, these undead corpses were required to return to their grave regularly to rest. When townspeople believed that someone had become a vampire, they would exhume the corpse and try to get rid of the evil spirit.

They might try an exorcism ritual, but more often they would destroy the body. This might entail cremation, decapitation or driving a wooden stake through the heart. Bodies might also be buried face down, so the undead corpses would dig deeper into the earth, rather than up into shallower ground. Some families secured stakes above the dead body so it would impale itself if it tried to escape.

The Strigoi: Living and Dead

The vampires in Moldavia, Wallachia and Transylvania (now Romania) were commonly called strigoi. Strigoi were almost exclusively human spirits who had returned from the dead. Unlike the upir or vrykolakas, the strigoi would pass through different stages after rising from the grave.

Initially, a strigo might be an invisible poltergeist, tormenting its living family members by moving furniture and stealing food. After some time, it would become visible, looking just as the person did in life. Again, the strigo would return to its family, stealing cattle, begging for food and bringing disease.

Strigoi would feed on humans, first their family members and then anyone else they happened to come across. In some accounts, the evil spirits would suck their victims' blood directly from the heart.

Initially, a strigo needed to return to the grave regularly, just like an upir. If townspeople suspected someone had become a strigo, they would exhume the body and burn it, or run spikes through it. But after seven years, if a strigo was still around, it could live wherever it pleased.

It was said that strigoi would travel to distant towns to begin new lives as ordinary people, and that these secret vampires would meet with each other in weekly gatherings.

In addition to undead strigoi, referred to as strigoi mort, people also feared living vampires, or strigoi viu. Strigoi viu were cursed living people who were doomed to become strigoi mort when they died. Babies born with abnormalities, such as a tail-like protrusion or a bit of fetal membrane tissue attached to the head (called a caul), were usually considered strigoi viu.

If a strigoi mort living among humans had any children, the offspring were cursed to become undead strigoi in the afterlife. When a known strigoi viu died, the family would destroy its body to ensure that it would not rise from the grave.

Vampire Hysteria

In other parts of eastern Europe, strigoi-type creatures were known as vampir, or vampyr, most likely a variation on the Russian upir. Western European countries eventually picked up on this name, and "vampyr" (later "vampire") entered the English language.

In the 17th and 18th centuries, vampire hysteria spread through eastern Europe. People reported seeing their dead relatives walking around, attacking the living. Authorities dug up scores of graves, burning and staking the corpses of suspected vampires.

Word of the vampire scare spread to western Europe, leading to a slew of academic speculations on the creatures, as well as vampire poems and paintings. These works in turn inspired an Irishman named Bram Stoker to write his vampire novel, "Dracula."

The Count Counts!

In eastern European folklore, you could ward off a vampire by scattering seeds on the ground, either on top of the vampire's grave or outside your house. Vampires were said to be obsessive creatures, and they were compelled to count all the seeds.

If you hid a nail in the seeds, it would prick the vampire midway through the count. The vampire would then drop the seeds and have to start all over again.

Bram Stoker's 'Dracula': The Birth of a Legend

Abraham (Bram) Stoker, a theater manager and part-time novelist, was not the first author to feature the vampire in a literary work, but his version is the one that really caught on. This is largely due to the novel's unforgettable villain, Count Dracula, as well as the foreboding setting.

Stoker arrived at both elements through extensive research. He set much of the action in the mysterious mountains of the Transylvania province of Romania, and he based his vampires on eastern European and gypsy folklore.

Selectively sampling from several versions of the vampire myth and adding some details of his own, Stoker formed the standard for the modern vampire. Unlike the vampires in the eastern European tradition, Stoker's monster loses power in the sunlight, is repelled by crucifixes and has acute intelligence.

Interestingly, Stoker's vampires do not have reflections, while many earlier vampire creatures were fascinated by their own reflection.

Stoker's research also turned up a name for his villain. The original Dracula was a real person, Prince Vladislav Basarab, who ruled Wallachia in the mid 1400s. His father was known as Vlad Dracul (translated as either "Vlad the dragon" or "Vlad the devil"), in recognition of his induction into a society called The Order of the Dragon.

Vlad Jr. was sometimes referred to as Vlad Dracula, meaning "son of Dracul," but more often he was called "Vlad Tepes," meaning "Vlad the Impaler." This was in reference to Vlad's predilection for impaling his enemies on long wooden stakes.

The Evolution of the Vampire in Modern Media

The real Dracula had a reputation for unfathomable brutality (a reputation many Romanians claim is inaccurate), but there is not much evidence showing that people believed he was a vampire.

Stoker's fictional villain is not closely modeled after the real Dracula, though they are sometimes linked in movies based on the book. Mainly, Stoker borrowed the name of the prince, as well as his social standing. Unlike the wandering, homeless strigoi, Stoker's vampire was a wealthy aristocratic type, hiding out in a grandiose castle.

In the 1927 play "Dracula," and the film adaptation that followed in 1931, Bela Lugosi embraced this aristocratic notion, playing the count as a suave, sophisticated gentleman. This play also introduced Dracula's familiar outfit: black formal wear and a billowing black cape.

In the novel "Dracula," the count is described as a withered, ugly old man, more like Max Shreck's portrayal in the 1922 silent film adaptation, "Nosferatu" than Lugosi's presentation. But the suave Dracula caught on, showing up in scores of vampire movies, television shows and cartoons.

The vampire has continued to evolve over the years, as novelists and filmmakers reinterpret and expand the mythology. In Anne Rice's popular novels, she takes vampires to the next level, giving them a conscience and a range of emotions. In her work, vampires are not necessarily evil — they are presented as real, rounded people. On the television show "Buffy the Vampire Slayer," creator Joss Whedon has pursued similar ideas, exploring the idea of a vampire with a soul.

A 'Real Vampire'?

Throughout history, there have been a number of living people who exhibited vampire-like behavior. The most famous historical vampire was Elizabeth Bathory, a Transylvanian noblewoman who lived from 1560 to 1614.

Bathory, who was terrified of aging, became convinced that bathing in blood (and perhaps consuming it) was the secret to maintaining a youthful appearance.

To this end, she tortured and killed hundreds of people, mostly young women. Eventually, she was tried for her crimes and imprisoned in a small room in her castle, where she died.

While the majority of vampire scholars focus on the cultural roots of vampire lore, some historians have looked to physical origins. There is no scientific evidence of actual vampires, but there are a number of real medical conditions that might result in vampiric behavior or appearance.

Medical Conditions Mimicking Vampirism

One of the most interesting "vampire diseases" is porphyria. Porphyria is a rare disease characterized by irregularities in production of heme, an iron-rich pigment in blood. People with the more severe forms of porphyria are highly sensitive to sunlight, experience severe abdominal pain and may suffer from acute delirium.

One possible treatment for porphyria in the past might have been to drink blood, to correct the imbalance in the body (though there's no clear evidence of this). Some porphyria sufferers do have reddish mouths and teeth, due to irregular production of the heme pigment. Porphyria is hereditary, so there may have been concentrations of sufferers in certain areas throughout history.

A more likely physical root of vampirism is catalepsy, a peculiar physical condition associated with epilepsy, schizophrenia and other disorders that affect the central nervous system.

During a cataleptic episode, a person essentially freezes up: The muscles become rigid, so that the body is very stiff, and the heart rate and respiration slow down. Someone suffering from acute catalepsy could very well be mistaken for a corpse.

Today, doctors have the knowledge and tools to accurately determine whether or not someone is alive, but in the past, people would decide based only on appearance. Embalming was unknown in most of the world until relatively recently, so a body would have been put right in the ground as is.

A cataleptic episode can last many hours, even days, which would allow enough time for a burial. When the person came to, he or she might have been able to dig themselves out and return home. If the person did suffer from a psychological disorder, such as schizophrenia, he or she might have exhibited the strange and disturbing behavior associated with vampires.

Decomposition and Misunderstandings of Death

The behavior of actual corpses might have suggested vampirism as well. After death, fingernails and hair often appear to continue growing because the surrounding skin recedes, which may give the impression of life. Gases in the body expand, extending the abdomen, as if the body had gorged itself.

If you were to stake a decomposing corpse, it could very well rupture, draining all sorts of fluids. This might be taken as evidence that the corpse had been feeding on the living.

Psychological Roots of Vampire Lore

While these conditions might have fueled a fear of the undead, the origins of vampire mythology are most likely psychological rather than physical. Death is one of the most mysterious aspects of life, and all cultures are preoccupied with it to some degree.

One way to get a handle on death is to personify it — to give it some tangible form. At their root, Lamastu, Lilith and similar early vampires are explanations for a terrifying mystery, the sudden death of young children and fetuses in the womb. The strigoi and other animated corpses are the ultimate symbols of death; they are the actual remains of the deceased.

Vampires also personify the dark side of humanity. Lilith, Lamastu and the other early vampire demonesses are the opposite of the "good wife and mother." Instead of caring for children and honoring a husband, they destroy babies and seduce men.

Similarly, undead vampires feed on their family, rather than supporting it. By defining evil through supernatural figures, people can get a better handle on their own evil tendencies and externalize them.

The appearance of so many vampire-like monsters throughout history, as well as our continued fascination with vampires, demonstrates that this is a universal response to the human condition. It's simply human nature to cast our fears as monsters.

A Psychic Twist

One modern variation on the vampire legend is the "psychic vampire." These self-identified vampires claim that they crave psychic energy from others and have the power to drain it without the person's knowledge.

Psychic vampires typically attempt to drain life-force energy through meditation and concentration. If they do not feed, they say, they will become weak as if they had not eaten.

According to some believers, this sort of vampire has been around for thousands of years. Some claim this phenomenon inspired the undead vampires of folklore.

Real Bloodsuckers

In many modern movies and books, vampires can take the form of a vampire bat, a real animal that feeds on blood. In actuality, vampire bats don't usually kill their prey, and they pose little threat to humans. In fact, they are small, reclusive, docile animals.

Vampiric shape-shifters go back thousands of years, but the particular connection to vampire bats is fairly recent. Vampire bats are only found in Central America and South America, so the Europeans and Asians who originally conceived of these monsters didn't know about them. When European explorers discovered the strange animals, they were soon incorporated into the vampire myth.
