Mask (human face, possibly representing Xiuhtecuhtli) made of cedro wood (Cedrela odorata) and covered in turquoise mosaic with scattered turquoise cabochons. The pierced elliptical eyes worked in mother-of-pearl (Pinctada mazatlantica) and the teeth are made of conch (Strombus) shell, although two are modern synthetic replacements. The eyelids were gilded. The interior surface of the mask is painted with cinnabar. The wood was carved to produce a curve and the underlying contours of the face.
