Tezcacoacatl (Mdz18r)
This compound glyph for the title Tezcacoacatl merges two elements, a mirror (tezcatl), which is repeated five times, and a snake or serpent (coatl). Thus, the serpent has five mirrors along the part of its body that shows (the upper half). These mirrors are filled with red and a black dot in the middle. Surrounding the circles is a black skin. The belly of the snake is white. Its head is a mottled pink and white color. It is shown in profile, looking to the viewer's right. Its eye is open. Its red tongue is bifurcated.

From the contextual/historical image, one can see that the title glyph is attached to a man's head. His name glyph is farther to the left, Ome Cuauh (or Cuauhtli, eagle). For another example of a serpent with circles on its skin, such as Tezcacoacatl has, see the example of one of the names Itzcoa from the Matrícula de Huexotzinco, below.
