The story is retold by many authors so you may find slightly different versions all over the internet. The account is based on a 14th century Bohemian report and the events are said to have happened in 1345.
It is in that year that the wife of a potter died before she could be put on trial for suspicion of being a witch. The townsfolk decided to bury her at a crossroad since it was the custom at that time.
But she did not find peace and started to leave her grave at night, appearing to many people under various forms [beasts] and attacking them.
When her grave was opened it was discovered that she had eaten half her shroud so she was labeled a vampire and staked through the heart.
Enraged by this she pulled out the stake and started to use it as a weapon in her more vicious prowls in the night. More people were killed and the villagers decided to cremate her.
Only after she was burned to ashes did the attacks stop!
It is said that a whirlwind was seen at the place where the corpse had been cremated.
Among the papers that cover these happenings I mention: Erasmus Francisci`s “Der Höllische Proteus” ; “The Vampire, His Kith and Kin” by Montague Summers ; “The Vampire Book: The Encyclopedia of the Undead” by J. Gordon Melton; “Vampires” by Rosemary Ellen Guiley and many many others!
NOTE: You may find the name of the village written as Lewin. On a Czech map you will find it as Levin.
