Although Teotihuacan did not arise from a spontaneous prehistoric obscurity, the purity of the character of its builders and the singularity of their works does not accuse any direct affiliation, nor does it allow those responsible to be identified as some ethnic group.
The Frenchman, Desiré Charnay, who in 1880 put into effect a preliminary excavation of the City of the Gods, believed that it was a Toltec city, like many others who accompanied him in the investigation. However later studies established the beginning of the history for the Toltec civilization in the ninth century of our era and identified its capital, Tollan, with the present city of Tula in the state of Hidalgo. However the Toltec hypothesis should not be left totally discarded. In fact, their chronicles and mythological epics written in Nahuatl, the Aztecs generally called "Tolteca" a very old city of which they claim to have inherited their religious tradition, and their wisdom in part. On the other hand, they seem to have mentioned a repeated number of times Teotihuacán, and who for centuries, created the most beautiful funeral masks and the most perfect works of ceramics in the classical period. But possibly there is a deeper meaning that has to be distinguished, and perhaps also alchemist, in the expression of great artists, that also it is left to the initiators of the Fifth Sun, the Sun born Teotihuacán, according to the scriptures in Nahuatl, to be able to ascend To the zenith, the center of the universe.
The founders of the City of Gods would be considered spiritually as the era of movement, long afterwards. In this case, this is what allows the adventurous to speculate, although it is extremely bright, what Mexican archaeologist Laurette Sejourne has written for years, about Nahuatl mythology and its iconography.
The rest of the studies, consider that the theocratic aristocracy that founded and governed Teotihuacán, came from another region, probably the East, perhaps of the coast of the Gulf. The Mexican, Jimenez Moreno, and the French Jacques Soustelle speak of the Totonacas, a town established in the Northwest of Veracruz, near its former capital, El Tajin, when the Spaniards arrived. Definitely, the City of the Gods still maintains a secret identity of the race that transformed it, two millennia ago, into the spiritual metropolis of ancient Mexico.
