Ancient DNA Unveils Secrets of Poland’s 400-Year-Old Vampire Burial

Uncovering the Identity and Precautions of Zosia

Scientists recently published the first systematic research on Zosia in the Journal of Archaeological Science: Reports, utilizing ancient DNA and cutting-edge laboratory techniques to understand who she was and why she faced such extreme post-mortem measures. Dariusz Poliński, a professor at the Institute of Archaeology at Nicolaus Copernicus University in Toruń, Poland, and lead author of the study, noted the exceptional nature of the grave. It was unusual that there were two precautions, two methods of showing that this skeleton should be kept in the grave — so the fear of the body coming back to life was greater, Poliński explained. Excavations at the Pień site near Dąbrowa Chełmińska began in 2005, uncovering a total of 101 graves used over roughly four generations in the seventeenth century. Researchers determined the burial ground was likely Protestant due to the complete absence of Catholic devotional items like crosses and medals. During this era, Protestant groups from Germany and the Netherlands—primarily Lutherans and Mennonites—lived alongside the predominantly Catholic Polish population. While padlocks have occasionally been recovered from Jewish cemeteries in Poland, study authors confirmed the site carried no other characteristic features of a Jewish grave. John Blair, a University of Oxford professor emeritus of medieval history and archaeology who was not involved in the new study, emphasized the cultural context of the findings. They were undoubtedly perceived as potentially dangerous corpses, that might harm the living if not disabled in this way, Blair said of females buried with sickles over their throats. Corpse-killing measures are widely attested in burials, at many dates and across the world, though this specific practice seems to be distinctive of early modern Poland, added Blair, author of Killing the Dead: Vampire Epidemics from Mesopotamia to the New World.

Deviant Burials in a 17th-Century Polish Cemetery

Zosia’s grave was far from an isolated anomaly within the Pień burial ground. Several dozen graves in the rural field featured atypical body arrangements or restraining objects that researchers classified as deviant. These unusual interments included a child buried face down, a skeleton positioned as in a crucifixion, and graves encircled with stones around the skull to prevent biting or movement. The physical layout of the cemetery further highlights how society marginalized these individuals. Set away from the village on a slope by a crossroads and far from any church or chapel, the field likely served as a burial place for individuals rejected by society, irrespective of their social status, who were likely feared even after death, according to the research team. Such burial places were generally omitted from written sources, which explains the absence of source data concerning them. This mode of burial was applied to suicides, heretics, outsiders without municipal citizenship, vagrants, and the tragically deceased. Physical evidence from Zosia’s tomb reveals specific details about how the protective measures were applied. A triangular-shaped padlock was fastened to the corpse’s big toe during the initial burial, though it was eventually found unlocked. Meanwhile, the sickle—crafted with a handle made of birch, alder, or maple wood—was positioned over her neck at a later date, poised to decapitate her if she attempted to rise. Researchers hypothesized that the blade was added before the body fully decomposed, as no skeletal joints were found detached or displaced.
