‘Which Aztec god?’

hi you came to dallow primary school on tuesday the 16th of april. this model lookes like an ancient god

judging by the paint facial double ray, the skin appears to have the dress, and the breastplate, I would say that this are atributes of Xipe totec as these are shown in the Borgia Group codices.

This is not a tourist souvenir. This was found in an excavation.

No idea. It’s one of those things they sell to tourist. It has many atributes to other gods. For example the corn head, the “face paint”, the type of jewelry, etc...
