Note 2 — Chapter V · DEITIES OF THE EARTH AND GROWTH PROPER
Reading edition
Another of her distinguishing characteristics, as has been remarked, is the black colouring in the region of the mouth, which frequently extends to and includes the tip of the nose and chin and, as Sahagun states, this was effected with liquid rubber, as in the case of the Fire-god. The small patch or circle on her cheek is also commented upon by Sahagun, who says, “a hole has she placed on her cheek”—the “hole” being probably a disk of rubber with a perforated centre. As an alternative to this we find in Codex Borgia two broad horizontal lines and in Codex Borbonicus several short, vertical black lines below the eye, and it would seem that the concentric circle on the shield of the goddess in the Sahagun MS. has the same meaning—that is, it is probably a symbol of sex.2 In some representations her skirt is covered with crescent-shaped objects perhaps typical of her symbol—excrement.
