A multimethod analysis for tracing Gravettian red ochre provenance at Arene Candide Cave (NW Italy)
Bibliographic record
Abstract
ABSTRACT Arene Candide Cave, a key site for Western Mediterranean prehistory, is famous for the discovery of the richly adorned Mid–Upper Palaeolithic burial of the ‘Young Prince’ and for its use as a burial site at the end of the Pleistocene (Late Epigravettian). In both contexts, red ochre was a conspicuous element of the burial practices. Unfortunately, few provenance studies and analytical data are available for the pigments recovered in the cave. Likewise, the geographical and geological origins of these colouring materials, which are naturally abundant in the Liguro‐Provençal Arc, have received little to no attention despite their technical and symbolic value. During the 2008–2013 archaeological excavation at Arene Candide Cave, micromorphological samples were collected from the Upper Palaeolithic portion of the 1940s stratigraphic profiles, permitting a first description of site formation processes during the Gravettian. This led to the recognition of a Late Gravettian layer characterized by poorly sorted sediment rich in very small ochre fragments. This study establishes the provenance of these ochre fragments through the combined use of optical microscopy, scanning electron microscopy and X‐ray diffraction. The results reveal a strong correspondence between the Arene Candide ochres and local ore sites, which were never considered before as potential sources. The mineralogical composition of the samples, characterized by the presence of barium sulphate and iron oxides, indicates that the Finalese area (NW Liguria) in which the site is located was the most likely source of the colouring pigments used by the Upper Palaeolithic hunter‐gatherers of the Arene Candide Cave.

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.
