From the ancient Mayan language: hunab ku, translates as "giver of movement and measure". Consists of: hun, "unique", "only"; nab, "measure" and "movement" and ku or kub, "giver". The Anahuac civilization is only one, regardless of how many different cultures in time and space represent it. So that the Maya, Nahua or Zapotec, just to mention three of the more than two hundred peoples that existed prior to the European invasion and occupation. So by having the same " philosophical-cultural matrix" known as Toltecáyotl, we are not in front of "different civilizations", i.e., the Maya are not a civilization in themselves, are on the other hand, part of a whole entity known as civilization of the Cem náhuac.
So the philosophical-spiritual concept of Hunab Ku, "giver of movement and measure", is not only creation of the Mayan culture, in the nahuatl language (lingua franca of the Cem ?náhuac for thousands of years) is named as Tloque Nahuaque. As well as Chac, representing the world luminous energy symbolized by water, also exists in the Zapotec culture with the name of Cosijo, and likewise found in the nahua culture named Tlaloc. All three share the same philosophical-religious root, but each culture represented it ichnographically differently, however all three concur in depicting a sort of goggles and a snake tongue.
