Using parasite analysis to identify ancient chamber pots: An example of the fifth century CE from Gerace, Sicily, Italy
Bibliographic record
Abstract
Chamber pots are perhaps one of the more challenging ceramic forms to identify with certainty in Roman pottery studies, despite the availability of detailed ceramic typologies. Here, we describe the analysis of mineralized concretions taken from a Sicilian ceramic vessel of the fifth-century CE, and propose paleoparasitology, the identification of intestinal parasites, as a helpful method for contributing to the detection of chamber pots. Microscope analysis of the mineralized concretions revealed the presence of eggs of the intestinal nematode Trichuris trichiura (whipworm), confirming that the vessel originally contained faeces. This is the first time that parasite eggs have been identified from concretions inside a Roman ceramic vessel. Systematic parasitological investigation of calcified deposits from ceramic vessels may therefore help to establish function. In addition, the identification of intestinal parasite eggs has the potential to advance our understanding of the sanitation, diet, and intestinal health of populations who used these chamber pots.

How this classification was reachedexpand
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.
