Quinametzin
In Aztec mythology, the Quinametzin Giants populated the world during the previous era of the Sun of Rain (Nahui-Quiahuitl). They were punished by the gods because they did not venerate them, and their peak-civilization came to an end as a result of great calamities and as a punishment from the heavens for grave sins they had committed. The construction of the pyramid of Cholula and the City of Teotihuacan (The Place Where Men Become Gods) was attributed to the Quinametzin Giants.
