huictli (MH497v)
This black-line drawing of the element huictli (digging stick) has been taken from the compound glyph of the personal name, Zacamol (see below). The shape sits at an angle and is triangular, with the wide end at the bottom.

Evidence that the huictli came to be called a coa in Mexican Spanish comes from the Spanish-language text in the Florentine Codex.
