Figurative aspects suggestive of infectious diseases in the ceramic pots of the pre-Columbian Moche culture. Analysis of the ceramics collection in the Larco Museum of Lima, Peru.

The historical-medical and anthropological studies, regarding Mesoamerica and South America, have been mainly focused on the great empires (Inca, Atzec, Maya), while other civilizations have been less investigated and only recently are gaining interest. In general, the paleopathological research provides interesting data to know the type of nutrition and the general environmental conditions as well as to point out some ritual mutilation practices, which were relatively frequent in the pre-Columbian cultures. A lot of civilizations flourished in the South America before the arrival of the Spanish Conquistadores in the new world. In the last years it is progressively increasing the interest for the study of the Moche culture as well as for a deeper knowledge of pathocenosis of infectious diseases in the Moche society. Human infectious diseases are known to have a frequent animal origin, in particular from domesticated species, although the species domesticated in the pre-Columbian era were a small number. The purpose of our paper has been to examine the archeological findings suggestive of infectious diseases in artistic ceramic pots, dating back to the Moche period. We examined the iconography of ceramic pots belonging to the collection of the Larco Museum in Lima and reproducing body signs suggestive of infectious diseases. We identified 8 handworks with very interesting features by a medical point of view. In these handworks there are signs and lesions possibly associated with infectious diseases: risus sardonicus, orbital edema, facial nerve palsy, dorsal kyphosis, face and skin lesions. These features are compatible with some infectious diseases, including: syphilis, Bartonella bacilliformis, leishmaniasis, Pott's disease and Chagas disease. A wide discussion about these handworks is provided.
