The Fifth Sun: Nanahuatzin Throws Himself into the Fire

Before the world had a sun, the gods gathered in darkness at Teotihuacan — the city of the gods, north of what is now Mexico City — and faced a problem. Someone had to become the sun. Someone had to throw themselves into the great sacred fire and burn.

Two volunteered.

Tecuciztecatl was magnificent. His offerings were rich — coral branches, red feathers, golden balls of grass, the best of everything. He was proud of his courage and expected to succeed. Nanahuatzin was the opposite in every way: small, scabbed with sores, poor in his offerings — dried sedge grass, cactus thorns, and blood drawn from his own diseased skin. He was not expected to amount to anything.

The fire was built. It blazed for four days. The gods stood waiting.

Tecuciztecatl approached the fire. The heat pushed him back. He gathered himself and approached again. The heat pushed him back again. Four times he approached; four times he retreated, face turned from the flames. His courage, as it turned out, was the kind that depends on things going well.

Then Nanahuatzin's turn came. He prayed. He looked at the fire, which was immense and terrible. And then he simply ran and threw himself in. The text says he didn't stop, didn't flinch, didn't close his eyes. He burned completely. He rose as the sun.

Tecuciztecatl, shamed by this, finally leaped in behind him. He rose as the moon. But the gods, observing that his leap had required an example — that he had needed someone else's courage before he found his own — struck his face with a rabbit and dimmed his light. The moon would be bright, but not as bright as the sun.

The story does not end with the rising of the sun. There is one more crisis: the sun would not move. It stood fixed in the sky, blazing but stationary. The gods understood what was required. They had to die — all of them — to give the sun the energy to travel. Quetzalcoatl, the wind god, sacrificed them one by one. Their deaths became the force that pulls the sun across the sky every day.

What the Aztec cosmology encodes here is a theology of radical sacrifice: the world is not stable, the sun is not guaranteed, life is maintained by ongoing expenditure, not passive existence. The small, diseased, humble god became the sun because he was willing to stop calculating. The question the story leaves open — and it is a sharp one — is which of us is Tecuciztecatl, approaching and retreating, and which is Nanahuatzin, who simply ran.
