Archaeologists excavating a Medieval cemetery site in Kałdus, Poland, recently discovered hundreds of graves — among them, they found 14 anti-vampire burials. Some of these people were decapitated, others buried face-down, and still more were weighted down with stones. One of the major theories about ancient “vampire” graves is that people buried in this way were unhealthy or disabled, causing their compatriots to treat them differently in death because of their physical differences in life. A team of researchers set out to investigate diseases apparent on the bones of these 14 so-called vampires.
