Onyx Marble Mask
In Teotihuacan, during the 3rd and 7th century CE, masks depicted ideal human faces with geometric brows, triangle noses, oval mouth, and oval eyes. As seen in this specific mask, the eyes and mouth are indented which could potentially be a space for shells or other stones. This mask was made by onyx marble, which is pretty heavy and thus was probably not a wearable mask (no holes for eyes/mouth either). (1) Most masks in Teotihuacan were made from heavy stones that typically weighed around 3-6 kilograms, meaning they could not be worn. It did have holes on the sides which could mean it could have been attached to other sculptures of deities, or even buried. (2)
