Ecatilma (MH860r)
This black-line drawing of the simplex glyph for the personal name Ecatilma ("Wind Cape" of "Cape of Ehecatl," attested here as a man's name) shows a square cape (tilmatli) with the profile of an anthropomorphic head facing right. The head has short spiky hair and a large beak-like mouth, apparently the device through which Ehecatl, the divine force of wind, blew the wind.

Gabrielle Vail and Christine Hernández (Re-Creating Primordial Time, 2013, ) describe Ehecatl as the wind aspect of Quetzalcoatl, and they note that Ehecatl "wears a buccal (duck) mask through which to blow wind." That the "beak" may have been perceived as a blowing device is supported by the glyph for Pitztli (below).
John Montgomery drew a group of wind glyphs (possibly mainly Mixtec), showing the variety of ways the blowing device might look. It is published in FAMSI, Inc.
Gordon Whittaker has recommended preserving the spelling of Eca-, even when the intention may well be Eheca-. The Eca- spelling is pervasive. The dictionary differentiates between ecatl (air, breath) and ehecatl (wind). The reduplication of the first syllable seems to suggest there is more volume to the air and/or it has greater movement. The "cape" in this glyph is just a white square, but we know from the gloss what is meant.
