Motecuhzoma (Mdz15v)
This compound glyph for the personal name Motecuhzoma (here apparently Motecuhzoma Xocoyotzin, the Younger) features a diadem in profile, facing toward the viewer's right. This turquoise-colored diadem (the xiuhhuitzolli) is a glyph for lord (tecuhtli). The hair, tzontli, which appears under the diadem, may provide a phonetic complement for zoma (to frown in anger), the final part of the name. The small turquoise-colored elements--one floating in the air and one attached to the hair--have yet to be analyzed, but one may be a lip plug and the other an ear plug.

The museum comparison, below, also includes the diadem and hair--along with perhaps the lip plug and ear plug. Speech scrolls on this stone carving may point to the fact that Motecuhzoma was a huei tlatoani (great ruler, or tlahtoani, with the glottal stop), given that speech scrolls can stand for the verb tlatoa, to speak.

The four elements counted here include the diadem, hair, lip plug, and ear plug, which all seem to be diagnostic for Motecuhzoma.

Motecuhzoma. A bas relief stone carving on the underside of the lid of the so-called "Caja de Moctezuma Xocoyotzin," Museo Nacional de Antropología e Historia, Salón Mexica. The Museo describes the headdress as a xiuhitzolli [xiuhhuitzolli], which is the turquoise diadem. The museum signage also refers to it as the "imperial headdress."
