cuauhtetepoyo (Mdz20v)
This multicolored painting is an iconographic example for the noun cuauhtetepoyo, a Mexica war shield with an eagle-claw design. Red and white predominate in this shield, but turquoise blue, green, and yellow also appear. Colored feathers were prized for creating some of these works of art, which were apparently also carried onto the battlefields.

Claws and sharp nails were major themes in Nahua artistic design, perhaps for their ability to draw blood. Blood was a vital life force, and it was an offering to the divine forces as a way of pursuing the continuation of life. For another example of the cuauhtetepoyo chimalli, see Marc Thouvenot's vignette that is based on a detail from the Códice Matritense de la Real Academia.
