Deviant burials and social identity in a postmedieval Polish cemetery: An analysis of stable oxygen and carbon isotopes from the “vampires” of Drawsko
Bibliographic record
Abstract
Abstract Objectives Deviant burials can reveal important information about both social and individual identity, particularly when the mortuary record is supplemented by an examination of skeletal remains. At the postmedieval (17th to 18th c. AD) cemetery of Drawsko (Site 1), Poland, six individuals (of n = 285) received deviant, anti‐vampiristic mortuary treatment. A previous study using radiogenic strontium isotope ratios ( = 0.7112 ± 0.0006, 1 σ , n = 60) found that these “vampires” were in fact locals, not migrants to the region targeted for deviant burial due to their status as immigrant outsiders. However, considerable geologic overlap in strontium isotope ratios across the North European Plain may have masked the identification of at least some nonlocal individuals. This study further contextualizes strontium isotope ratios using additional biogeochemical data to test the hypothesis that additional nonlocals were present in the Drawsko cemetery. Methods Stable oxygen and carbon isotopes from the dental enamel of 58 individuals interred in both normative and atypical burials at Drawsko were analyzed. Results Both δ 18 O c(VPDB) ( = −4.5 ± 0.7‰) and δ 13 C ap isotope values ( = −13.6 ± 0.8‰) displayed little variability and were not significantly different between vampire and normative burials, supporting prior strontium results of a largely local population. Nevertheless, homogeneity in oxygen isotope values across other northern European sites makes it difficult to speculate about isotopic regional diversity, leaving open the possibility that additional migrants to the region remain undetected. Additionally, carbon isotope values point to a locally sourced diet dominated by C 3 resources but with some supplementation by C 4 goods that likely included millet, fitting with historic descriptions of postmedieval diet in Poland. Conclusions Those interred as vampires appear local to the region and thus likely underwent deviant funerary treatment due to some other social stigma not apparent from the skeleton.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
