hem, in which the colours of the hieroglyph chalchihuitl , green and red, with a white fringe, are reproduced, thus forming a kind of pictograph of her name. The same purpose is served by a large blue disk in the middle of the skirt. In Codex Vaticanus B she holds the bone-dagger and agave spike for ceremonial blood-letting. She stands on foaming water, on which floats a burnt-offering of firewood and rubber.
In the Aubin tonalamatl she is pictured as standing in a stream, down which swirl away a jewel-box, an armed man, and a woman.
