And I don't want to add fuel to a strange fire, but in 1764 when Jean-Jacques Rousseau wrote a letter to Beaumont regarding the absurdity of belief despite evidence, he used this as an example:

"If there is in this world a well-attested account, it is that of vampires. Nothing is lacking: official reports, affidavits of well-known people, of surgeons, of priests, of magistrates; the judicial proof is most complete."

Wasn't this the guy going around building animate porcelain dolls in suspiciously modern gothic-lolita dresses?
