Mask of Tlaloc
From: Mexico (Aztec/Mixtec)
Date: 15th-16th century AD
This striking mask is probably meant to be Tlaloc, the Aztec rain god. It is made of turquoise mosaic. Turquoise reminded the Aztecs of green leaves and life-giving water.
Tlaloc's face is made out of two serpents, one green and one blue. Each encircles an eye before they intertwine across the nose. Mosaic feathers flank the face and may have been part of a larger head ornament made of quetzal-bird feathers. The mask might have been worn by the priest that served Tlaloc in the Great Temple.
