The
Wikipedia article on vampires isn't much help. The only terms it digs up are "coven" (which was already suggested above), "house," and "basement." These seem to be only helpful suggestions based on very little evidence.
Dictionary.com does not ascribe this definition to any of the three words.
Vampires are a rather recent addition to the folklore of western Europe, first appearing in the early 1700s with the spread of legends from eastern Europe. Many of the now-standard characteristics of vampires in our modern folklore are completely apocryphal, such as having no reflection or not being able to survive exposure to sunlight. Apparently a minor Irish writer named Bram Stoker virtually invented the modern vampire in his famous 1897 novel
Dracula, mixing and matching traits from the entire catalog of spooky creatures, including werewolves.
This is a perfect illustration of the power of the printed word. Until the Industrial Revolution increased the productivity of human labor by more than one order of magnitude, more than 99% of the world population were subsistence farmers working 120-hour weeks. Even their children worked in the fields so only the children of aristocrats were sent to school. Most people were illiterate.
Industrial technology shortened the work week and can be said to have created "childhood" as we know it, giving children time to be educated, eventually establishing a phenomenon we now take for granted: universal literacy. But in addition, motor-driven printing presses created an explosion of reading material for all those newly-literate people.
A story made up by a man who was not even recognized as a writer in his own lifetime, based on a hodgepodge of old legends and beaten into shape by his own imagination, was spread by industrial technology and has become an iconic legend for a major segment of the earth's population.
