Origins of vampire beliefs
Many theories for the origins of
vampire beliefs have been offered as an explanation for the
superstition, and sometimes mass hysteria, caused by vampires.
Everything ranging from premature burial to the early ignorance of the
body's decomposition cycle after death has been cited as the cause for
the belief in vampires.
Slavic Spiritualism
Although many
cultures possess revenant superstitions comparable to the Eastern
European vampire, the Slavic vampire is the revenant superstition that
pervades popular culture's concept of vampire. The roots of vampire
belief in Slavic culture are based to a large extent in the spiritual
beliefs and practices of pre-Christianized Slavic peoples and their
understanding of life after death. Despite a lack of pre-Christian
Slavic writings describing the details of the "Old Religion", many
pagan spiritual beliefs and rituals have been sustained by Slavic
peoples even after their lands were Christianized. Examples of such
beliefs and practices include ancestor worship, household spirits, and
beliefs about the soul after death. The origins of vampire beliefs can
in Slavic regions can be traced to the complex structure of Slavic
spiritualism.
Demons and spirits served important functions in
pre-industrial Slavic societies and were considered to be very
interactive in the lives and domains of humans. Some spirits were
benevolent and could be helpful in human tasks, others were harmful and
often destructive. Examples of such spirits are Domovoi, Rusalka, Vila,
Kikimora, Poludnitsa, and Vodyanoy. These spirits were also considered
to be derived from ancestors or certain deceased humans. Such spirits
could appear at will in various forms including that of different
animals or human form. Some of these spirits could also participate in
malevolent activity to harm humans, such as drowning humans,
obstructing the harvest, or sucking the blood of livestock and
sometimes humans. Hence, the Slavs were obliged to appease these
spirits to prevent the spirits from their potential for erratic and
destructive behavior.
Common Slavic belief indicates a
stark distinction between soul and body. The soul is not considered to
be perishable. The Slavs believed that upon death the soul would go out
of the body and wander about its neighborhood and workplace for 40 days
before moving on to an eternal afterlife. Because of this, it was
considered necessary to leave a window or door open in the house for
the soul to pass through at its leisure. During this time the soul was
believed to have the capability of reentering the corpse of the
deceased. Much like the spirits mentioned earlier, the passing soul
could either bless or wreck havoc on its family and neighbors during
its 40 days of passing. Upon an individual's death, much stress was
placed on proper burial rites to ensure the soul's purity and peace as
it separated from the body. The death of an unbaptized child, a violent
or an untimely death, or the death of a grievous sinner (such as a
sorcerer or murderer) were all grounds for a soul to become unclean
after death. A soul could also be made unclean if its body were not
given a proper burial. Alternatively, a body not given a proper burial
could be susceptible to possession by other unclean souls and spirits.
An unclean soul was so fearful to the Slavs because of its potential
for vengeance.
From these deeply implicated beliefs
pertaining to death and the soul derives the invention of the Slavic
concept of vampir. A vampire is the manifestation of an unclean spirit
possessing a decomposing body. This undead creature is considered to be
vengeful and jealous towards the living and needing the blood of the
living to sustain its body's existence. Although this concept of
vampire exists in slightly deviating forms throughout Slavic countries
and some of their non-Slavic neighbors, it is possible to trace the
development of vampire belief to Slavic spiritualism preexisting
Christianity in Slavic regions.
Pathology
Decomposition
Paul
Barber in his book Vampires, Burial and Death has described that belief
in vampires resulted from people of pre-industrial societies attempting
to explain the natural, but to them inexplicable, process of death and
decomposition.
People sometimes suspected vampirism when a
cadaver did not look as they thought a normal corpse should when
disinterred. However, rates of decomposition vary depending on
temperature and soil composition, and many of the signs are little
known. This has led vampire hunters to mistakenly conclude that a dead
body had not decomposed at all, or, ironically, to interpret signs of
decomposition as signs of continued life. Corpses swell as
gases from decomposition accumulate in the torso and the increased
pressure forces blood to ooze from the nose and mouth. This causes the
body to look "plump," "well-fed," and "ruddy"—changes that are all the
more striking if the person was pale or thin in life. In the Arnold
Paole case, an old woman's exhumed corpse was judged by her neighbours
to look more plump and healthy than she had ever looked in life.
The exuding blood gave the impression that the corpse had recently been
engaging in vampiric activity. Darkening of the skin is also caused
by decomposition. The staking of a swollen, decomposing body could
cause the body to bleed and force the accumulated gases to escape the
body. This could produce a groan-like sound when the gases moved past
the vocal cords, or a sound reminiscent of flatulence when they passed
through the anus. The official reporting on the Peter Plogojowitz case
speaks of "other wild signs which I pass by out of high respect".
After
death, the skin and gums lose fluids and contract, exposing the roots
of the hair, nails, and teeth, even teeth that were concealed in the
jaw. This can produce the illusion that the hair, nails, and teeth have
grown. At a certain stage, the nails fall off and the skin peels away,
as reported in the Plogojowitz case—the dermis and nail beds emerging
underneath were interpreted as "new skin" and "new nails".
