In the Nahua cosmogony, Quetzalcoatl, it has several names and attributes. He is the god who transforms death into life, the carnal into divine, and the instinctive into civilized. This synthesizes the most important and complex cultural of the Nahua world, which properly originated from the great Aztec civilization.
Thanks to the sacrifice of this God, the human beings received the life.
The sacrifice includes, the trip that made to Mictlan that is the region of the dead, adventure that is manifest in the legend of the suns. According to this the Gd departs towards the region in search of precious bones that will be useful for the creation of the humanity. Mictlantecutli, lord of the region of the dead where there were no doors or windows, tests him and prevents him from carrying the bones of the past generations. Quetzalcoatl aided by his bees and worms is finally able to take the bones with him. He leads them to Tamoanchan, where with a little help from Quilaztli, he makes them germinate, grinds them and puts them in a precious vessel. Upon the vessel, it makes his virile member bleed to inspire life in them. Hence the title of mazehuales, given to man, which means, those deserved by penance.
After creating humanity, Quetzalcoatl, guides them and has to feed them. The black ant asks; Where is the corn? And this takes him to Tonacatepetl which is known as the hill of sustenance, where he gives them corn. Then the god teaches the Nahuas to cultivate it, giving it its origin to agriculture.
