Short answer: Aztec myth (more precisely Mexica myth, one branch of a Nahua world whose descendants live in Mexico today and still speak Nahuatl) runs on one uncomfortable idea: existence is not free. The universe has already collapsed four times, we live in the fifth attempt, and it keeps moving only because somebody keeps paying for it. New here? Start with what mythology actually is, and note that the feathered serpent belongs to a much larger family of serpent gods than you would expect.
The main gods
| Name | Domain | The story in one line |
|---|---|---|
| Quetzalcoatl | Wind, knowledge, the morning star | The feathered serpent who went down to the land of the dead and bled on old bones to make us |
| Tezcatlipoca | Night, fate, conflict, kingship | The smoking mirror: brother, rival and dark reflection of Quetzalcoatl |
| Huitzilopochtli | The midday sun, war, the Mexica state | Born fully armed to defend his mother, and he chose where his people would build their city |
| Tlaloc | Rain, storms, mountains, farmland | Far older than the Mexica: he gives the harvest and he takes it away |
| Coatlicue | Earth, birth and death at once | The serpent-skirt mother, made pregnant by a ball of feathers and nearly killed by her own children for it |
| Coyolxauhqui | The moon | Huitzilopochtli's sister, cut down at the foot of the mountain: the moon beaten by the sun every dawn |
| Mictlantecuhtli | The underworld | Lord of Mictlan, who keeps the bones of every earlier humanity and hates lending them |
| Xolotl | Twilight, twins, dogs, the evening star | Quetzalcoatl's dog-headed twin, who walks the sun down through the night |
The five suns
| Sun | How that world ended |
|---|---|
| First, Four Jaguar (Tezcatlipoca's) | Jaguars came out of the dark and ate the people |
| Second, Four Wind (Quetzalcoatl's) | A hurricane swept it clean; the survivors became monkeys |
| Third, Four Rain (Tlaloc's) | Fire fell from the sky; the survivors became birds |
| Fourth, Four Water (Chalchiuhtlicue's) | A flood lasting 52 years; the survivors became fish |
| Fifth, Four Movement (ours) | Not yet, but the sources agree: earthquakes, and no sixth world |
The serpent who bled to make people
After the fourth world drowned, nothing was left of humanity but bones, stacked in Mictlan. Quetzalcoatl went down for them, passed Mictlantecuhtli's trick test, then fell and broke the bones, which is why people come in different sizes. He ground the fragments like maize and bled onto the powder until it became people. This mythology starts not with a god commanding, but with a god cutting himself open.
Reaching Mictlan is its own journey: nine levels, four years, obsidian winds, and a last river you cross on the back of a dog, which is why dogs were buried with the dead. Compare it with three other underworld rulers.
An eagle on a cactus
Coatlicue was sweeping a temple when a ball of feathers made her pregnant. Her daughter Coyolxauhqui and four hundred sons came to kill her over the scandal; Huitzilopochtli was born adult and armed, defended his mother and sent his sister down the mountain in pieces. The Mexica carved that scene into stone at the foot of the Templo Mayor, so every sunrise replayed it.
The same god later told a wandering, unwelcome people to look for an eagle perched on a cactus. They found it on a marshy island nobody wanted and built Tenochtitlan there, under what is now central Mexico City. That eagle is on the Mexican flag: this mythology is not a museum piece, it is on the passport.
The Templo Mayor carried two shrines on one pyramid, Huitzilopochtli's and Tlaloc's: sun and rain, war and maize, sharing a summit.
Why the universe had to be fed
Two calendars ran at once, a 260-day ritual count and a 365-day year, meshing like gears and realigning every 52 years. At the end of each cycle every fire was put out while people waited to see whether the sun would return. That was not a metaphor to them.
The fifth sun was lit at Teotihuacan when a god threw himself into a bonfire and the others gave their blood to move it. Human offerings repaid a debt the gods had paid first. Two things are true about the scale: Spanish chroniclers had every incentive to inflate the numbers, and some reported figures are arithmetically impossible, while excavation at the Templo Mayor confirms the practice was real and organised.
Quick questions
Who is the most important Aztec god?
It depends who is asking. For the Mexica state, Huitzilopochtli: their own patron, tied to the sun, the army and the legitimacy of Tenochtitlan. Across Mesoamerica and across centuries, Quetzalcoatl: honoured from Teotihuacan to the Maya lowlands long before the Mexica existed, and remembered as the god who made people rather than the one who led an empire.
Why did the Aztecs practise human sacrifice?
Because they believed the sun ran on borrowed energy, four worlds had already ended and the gods had bled first. Offerings paid down a debt, which is also why priests and rulers drew their own blood with maguey spines. On the numbers, hold two facts together: colonial accounts had political reasons to exaggerate, and archaeology confirms the practice existed.
Is the Day of the Dead Aztec?
Not directly. Today's Día de Muertos is syncretic: Catholic All Saints and All Souls layered over Indigenous practices of feeding and welcoming the dead, plus a lot of twentieth-century Mexican nation-building. Older elements survive inside it, including the dog that guides the soul, but it is a living tradition with Mexica ancestry, not an Aztec festival kept intact.
Aztec myth is not in MythologyNow yet: our audio dramas live in Greece, Egypt and the Norse north. While the feathered serpent waits his turn, meet the gods we do narrate, pick a myth to listen to, or read about the symbols behind all of them.
