Teotl (MH575v)
This black-line drawing of the compound glyph for the personal name Teotl (“Deity” pr "Spirit," attested here as a man’s name) shows an anthropomorphic head in profile, facing toward the viewer's right. The curling bits that seem to suggest a stone (tetl) are a phonetic indicator for the start of the word teotl. The "stone" even has a diagonal stripe across the face, which further suggests that stone is meant for this phonetic purpose (not contributing any semantic meaning).

Glyphs for teotl in the Codex Mendoza (c. 1541) do not have faces; they are half-suns. But by 1560, in the Matrícula de Huexotzinco, Christian influences seem to have led to the use of faces on some teotl glyphs, such as this one. See comparisons, below. The glyph here is much like the one on MH576r, except that one has red colorant added.
