Mosaic mask of Tezcatlipoca

Mexica*/Mixtec, 15th-16th century AD
From Mexico

The skull of the Smoking Mirror

This mosaic is believed to represent the god Tezcatlipoca, or ‘Smoking Mirror’, one of four powerful creator deities, who were amongst the most important gods in the Mexica pantheon. The name ‘Smoking Mirror’ derives from the Nahuatl (Mexica) word tezapoctli, meaning ‘shining smoke’ and representations of Tezcatlipoca are typically characterised by distinctive black stripes on the face and a smoking mirror generally displayed in his headdress, at his temple or in place of a torn-off foot.

The base for the mosaic is a human skull. The skull is cut away at the back and lined with deer skin on which the movable jaw is hinged. Long deerskin straps would have allowed the skull to be worn as part of priestly regalia. Skull ornaments like this are depicted in the Mixtec Zouche Nuttal codex.

The mosaic decoration is worked in alternate bands of bright blue turquoise and black lignite. The eyes are made of two orbs of polished iron pyrite framed by rings made of white conch (Strombus) shell. The nasal cavity is lined with plates of bright red Spondylus (thorny oyster) shell.

The turquoise, lignite, pyrite and shell were all procured from the farthest reaches of the Mexica empire and beyond. The effort made in assembling this diverse selection of exotic materials emphasises the divine ‘other-worldly’ nature both of the mosaic and whoever wore or displayed it.

*The people and culture we know as 'Aztec' referred to themselves as the Mexica (pronounced 'Mé-shee-ka').
