tepetl (CQ)
This element of a hill or mountain (tepetl) has been carved from the compound glyph of the place name Huitziltepec. It is painted a green-brown. It comes to a point at the top, because the painter added a hummingbird head at the top.

This shape is not typical for a tepetl glyph. Besides the point, it does not have the curling rocky outcroppings nor the yellow and red horizontal lines at its base where water could spring forth. The design of hill glyphs in the Quetzalecatzin Codex look much like landscape paintings of hills, having apparently evolved away somewhat from traditional glyphs. Still, there are a few examples of the tepetl in the Quetzalecatzin that have a horizontal white line where the red and yellow lines typically appear in other manuscripts (see below).
