Djenné disease iconography
Surface bumps, pustules, and applied ridges on Djenné terracottas read as deliberate clinical depictions of dermatologic disease (smallpox, yaws, onchocerciasis) rather than ornamental scarification, per Imperato 2021.
Djenné disease iconography is the scholarly reframing — established with extensive medical-iconographic evidence by Pascal James Imperato in his 2021 Journal of Community Health article — of the surface bumps, pustules, ridges, and modelled lesions found across the Inland Niger Delta terracotta corpus (approximately 11th-16th century CE). The conventional reading of these features as ornamental scarification (carried across decades of auction-catalogue and gallery copy) is corrected to: deliberate, highly accurate clinical depictions of dermatologic conditions, principally smallpox, yaws (treponematosis), and onchocerciasis (river blindness).
Functional interpretation: the figures functioned in ritual-healing contexts in two principal modes: (1) protective effigies installed in shrine assemblies to guard against disease, and (2) transfer-of-burden objects used by healers in the symbolic transfer of disease from patient to figure. The interpretation links the Djenné corpus to other West African healing-figurine traditions (Senufo boli, Fon bocio, Songye nkisi-related practice) within a broader sub-Saharan ritual-medical framework.
Why the correction matters: the scarification misreading systematically erases the medical and religious purpose of the corpus, reducing what are ritual-clinical objects to merely "decorated" sculpture. The reframing is also relevant for legal/restitution arguments: the figures are not generic "tribal art" but specific ritual-medical instruments with high cultural-property weight in the Republic of Mali.

Current status online: absent from all public-facing online resources surveyed in the 2026-05 competitor audit; first content publishing the reframing has clear citation-priority advantage.
