Besides Tezcatlipoca, there were also other high gods, whose functions related to creation and generation, but, like many high gods among primitive peoples, the amount of active worship paid them was relatively small. Such were Tonacatecutli and his wife Tonacaciuatl, dwellers in the highest heaven, who were said to be Toltec deities, and were identified with Ometecutli and Omeciuatl, also associated with Tulan. The creation once over, they received little direct worship, save that appeals were made to them in invocations relative to pregnancy and birth. Tonacatecutli was also identified with Chicome Xochitl (“Seven Flower,” a calendrical name), in which manifestation he appeared as a fertility-god, and Tonacaciuatl was at times likewise identified with Xochiquetzal and Chicome Coatl. Attention has already been called to the manner in which the Aztec tried to add to the dignity of their tribal god by transferring to him the functions of other deities, and it is not therefore surprising to find in one passage that Uitzilopochtli is identified with Tonacatecutli. Connected with the creator-deities are two interesting personalities, Oxomoco (male) and Cipactonal (female). These were the prototypes of all magicians, patrons of the magical arts, assistants in the creation of men and in the discovery of maize, and general advisers in the migration of the Nahua tribes. The material attributes of these personages are not clear, and it is difficult to find a pictorial representation which can be said with certainty to portray either of them. As regards Mictlantecutli, the god of the underworld, the case is quite otherwise; he is very frequently shown, and nearly always takes the form of a skeleton, often with a stone knife in place of his nose (Fig. 4, _b_). Skulls and bones are his inevitable accompaniments, the owl is his bird, and his feminine partner was named Mictlanciuatl. Other elemental divinities, of rather nebulous attributes, were the sky-gods Citlalicue and Citlaltonac, who were associated with the creator-gods, the sun and the morning star; and also Yoaltecutli and Yoalticitl, night-deities, of whom the former seems to be identified with the sun and the constellation Gemini, and the latter with Teteoinnan.
