Chicomoztoc- The Origins of the Tribes that Settled in or Close to Mexico - This illustration depicts Chicomoztoc, with men and women. Chicomoztoc, which means "seven caves," the place from which the Aztecs believed they came, was the Nahautl word for the mouth or womb. In the Aztec myth of creation, the Mexica left the bowels of the earth and settled in Aztlán, from which they acquired the name Aztec and from where they undertook a migration southward in search of a sign for where they should settle once more.
