Tlazolteotl has been completely identified with the Teteo innan or Toci of Sahagun and other writers, but though she ranked as the Earth-mother of Mexico par excellence, there is no room for doubt that her worship was originally alien, and assuredly of Huaxtec origin. The Huaxtecs were a people of Maya origin or affinities, isolated from the main body of that race, dwelling on the east coast of Mexico, and retaining many of their peculiar customs; and it is noteworthy that a Huaxtecan goddess should be alluded to in Mexican tradition as coming to Tollan, the city of the Toltecs, the people whom so many writers have tried to identify with the Maya. As has been observed, she was accompanied at the ochpaniztli festival by a band of youths dressed to represent Huaxtecs, who in the Codex Borbonicus picture of the festival are shown as wearing the cone-shaped Huaxtec cap. She herself wears the Huaxtec nose-ornament in common with the octli-gods. She is repeatedly stated to have had her “home” in Cuextlan, the Huaxtec country, and there are good grounds for supposing that its inhabitants, of whose religion we know little, had brought the cult of the Earth-mother to such a pitch of complex perfection as rendered its absorption of the allied Mexican cults merely a matter of time and occasion. That she was originally a personification of the maize is also clear. In her songs she is alluded to as “the yellow bloom” and “the white bloom,” and the references to her dwelling in Tamoanchan, the western paradise where the maize was supposed to have had its mythical origin, and where she gave birth to Cinteotl, the young maize-god, proves her association with this food-plant. But she was also the Earth, the insatiable, lustful mother, who gives birth to Cinteotl the young maize-god, who is also the obsidian knife of sacrifice, for the Earth is the mother of stone. As Sin, she was also the mother of death, for Cinteotl in this guise was undoubtedly a god of fatality or doom. Like many other deities of the earth she may have had an almost plutonic significance, for she is called Tlalli Iyallo, “Heart of the Earth.” But I think that Seler (Fejérváry-Mayer, p. 145) has mistaken the true significance of this expression in applying to it the meaning “interior of the earth.” The word “heart” in the Nahua tongue does not necessarily mean “interior.” True, Tepeyollotl, the Earthquake-god, possessed a similar designation, but on the other hand the Quiche Popol Vuh alludes to the god Hurakan as “The Heart of Heaven,” and I take the expression to mean in general “soul, spirit,” rather than “interior.” But, again, deities of grain have very frequently a subterranean association, and, according to Duran’s description of the feast of the goddess, we find that she was supposed to make her coming known by an earthquake shock, and she is ruler of the thirteenth week, ce olin, which some authorities translate as “earthquake” or “earth-motion.”
