The Aztec Cosmology: Five Suns and the Creation of the Current World

The world has been created and destroyed four times before this one. We are living in the fifth sun — the fifth attempt by the gods to create a world that works, a world that can sustain human life, a world that will last. And this world, too, will end. The question is not whether it will end, but how — and what the human beings who inhabit it owe to the gods who created it.

The Aztec cosmology is one of the most dramatic and most philosophically sophisticated creation narratives in world mythology. It is not a story of a perfect world created by a benevolent god. It is a story of repeated failure and repeated renewal — of gods who sacrifice themselves to create a world, of worlds that fail and are destroyed, and of the current world as a fragile, precious achievement that requires constant maintenance through human participation in the divine order.

The Structure of the Aztec Universe

The Aztec universe is organized vertically into thirteen heavens above and nine underworlds below, with the earth — Tlaltipac — at the center. Each level of the heavens is inhabited by specific divine beings and governed by specific forces. The highest heaven — Omeyocan, the place of duality — is the dwelling of Ometeotl, the supreme dual deity who encompasses both the masculine and feminine principles of existence.

The earth is understood as a great disk floating on the primordial waters, divided into four quadrants by the four cardinal directions. Each direction is associated with a specific color, a specific deity, a specific tree, and a specific quality of energy: east (red, the direction of the rising sun and new beginnings), north (black, the direction of the underworld and death), west (white, the direction of the setting sun and the feminine), south (blue, the direction of the sun at its zenith and the forces of life).

At the center of the earth stands the axis mundi — the world tree that connects the underworlds below with the heavens above, the vertical axis around which the cosmos is organized. The Aztec capital Tenochtitlan — built on an island in the middle of Lake Texcoco — was understood as the center of the world, the point where the axis mundi meets the earth's surface.

The Five Suns: The Five Creations

The most important narrative in Aztec cosmology is the story of the Five Suns — the five successive creations of the world, each presided over by a different sun and each destroyed by a different catastrophe.

The First Sun: Nahui Ocelotl (Four Jaguar)
The first world was created by the god Tezcatlipoca — the Smoking Mirror, the god of darkness and sorcery — who became the first sun. This world was inhabited by giants who ate acorns. It lasted 676 years before Quetzalcoatl struck Tezcatlipoca into the water with a stone club. Tezcatlipoca transformed into a jaguar and destroyed the world, devouring all its inhabitants.

The Second Sun: Nahui Ehecatl (Four Wind)
The second world was created by Quetzalcoatl — the Feathered Serpent — who became the second sun. This world was inhabited by people who ate pine nuts. It lasted 364 years before Tezcatlipoca took revenge, causing Quetzalcoatl to fall from the sky. The resulting hurricane destroyed the world; the people were transformed into monkeys.

The Third Sun: Nahui Quiahuitl (Four Rain)
The third world was created by Tlaloc — the rain god — who became the third sun. This world was inhabited by people who ate aquatic seeds. It lasted 312 years before Quetzalcoatl caused a rain of fire to fall from the sky, destroying the world. The people were transformed into birds.

The Fourth Sun: Nahui Atl (Four Water)
The fourth world was created by Chalchiuhtlicue — the goddess of water and rivers — who became the fourth sun. This world was inhabited by people who ate wild maize. It lasted 676 years before a great flood destroyed it. The people were transformed into fish.

The Fifth Sun: Nahui Ollin (Four Movement)
The fifth world — our world — was created at Teotihuacan, the great city of the gods, in a ceremony of divine sacrifice. The gods gathered in darkness — for there was no sun — and two of them volunteered to sacrifice themselves to become the new sun and moon.

The proud and wealthy god Tecuciztecatl was expected to become the sun. But when the moment came to throw himself into the sacred fire, he flinched four times. The humble, diseased god Nanahuatzin — covered in sores, poor, and unassuming — threw himself into the fire without hesitation and became the sun. Shamed, Tecuciztecatl finally jumped and became the moon. But because he had hesitated, one of the gods struck the moon with a rabbit, dimming its light — which is why the moon is less bright than the sun, and why the Aztecs saw the image of a rabbit in the moon's face.

But the new sun and moon did not move. They hung motionless in the sky. The gods realized that the sun required blood to move — that the sacrifice of Nanahuatzin was not enough. And so all the gods sacrificed themselves, their blood setting the sun in motion. The fifth sun began to move across the sky, and the current world began.

The Debt of Blood: Human Sacrifice in Aztec Cosmology

The story of the Fifth Sun explains the Aztec practice of human sacrifice — one of the most misunderstood and most sensationalized aspects of Aztec culture. Human sacrifice was not cruelty or barbarism. It was a cosmic obligation — the repayment of the debt that human beings owed to the gods who had sacrificed themselves to create the current world.

The Aztec word for human sacrifice — nextlahualli — means "debt payment." The gods had given their blood to set the sun in motion; human beings owed their blood to keep it moving. Without the regular offering of human blood, the sun would stop moving, the world would end, and the darkness that preceded the fifth sun would return.

This understanding does not make human sacrifice morally acceptable by modern standards. But it does make it comprehensible — the expression of a coherent cosmological framework in which the relationship between human beings and the divine is one of mutual obligation, in which the gods have given everything and human beings owe everything in return.

The victims of Aztec sacrifice were not understood as simply killed. They were understood as transformed — as joining the divine order, as becoming part of the cosmic machinery that sustains the world. Warriors who died in battle or on the sacrificial stone became companions of the sun, accompanying it on its journey across the sky. Women who died in childbirth — understood as a form of battle — became companions of the sun on its journey from noon to sunset.

Huitzilopochtli: The Sun God and God of War

Huitzilopochtli — the Hummingbird of the South — is the patron deity of the Aztec people and the god of the sun and of war. He is the divine force that drives the sun across the sky each day, defeating the forces of darkness and the stars that would prevent the sun from rising. His daily victory over the darkness is the cosmic drama that human sacrifice is designed to support.

Huitzilopochtli's birth is one of the most dramatic narratives in Aztec mythology. His mother Coatlicue — the earth goddess — was sweeping the temple when a ball of feathers fell from the sky and impregnated her. Her daughter Coyolxauhqui and her four hundred sons — the stars — were outraged by their mother's mysterious pregnancy and decided to kill her. But as they attacked, Huitzilopochtli was born fully armed from his mother's womb, defeated his siblings, and dismembered Coyolxauhqui, throwing her body to the bottom of the mountain.

This myth is enacted every day: Huitzilopochtli (the sun) defeats the stars and the moon (Coyolxauhqui) at dawn, driving them from the sky. The great circular stone of Coyolxauhqui — discovered at the base of the Templo Mayor in Mexico City in 1978 — depicts the dismembered moon goddess at the base of the pyramid, just as the myth describes.

Quetzalcoatl and Tezcatlipoca: The Cosmic Duality

The central dynamic of Aztec cosmology is the opposition and interaction between Quetzalcoatl — the Feathered Serpent, the god of light, of wind, of the morning star, of civilization and sacred knowledge — and Tezcatlipoca — the Smoking Mirror, the god of darkness, of sorcery, of the night sky, of the unpredictable forces of fate.

These two gods are not simply good and evil. They are the complementary principles of existence — the light and the dark, the ordered and the chaotic, the civilized and the wild — whose interaction generates the dynamic tension that makes the world possible. The story of the Five Suns is, in part, the story of their ongoing conflict and cooperation — each destroying the other's creation, each contributing to the eventual creation of the current world.

Tezcatlipoca's obsidian mirror — the smoking mirror that gives him his name — is the instrument through which he sees all things: the past, the present, the future, the hidden thoughts of human beings. It is the mirror of fate, the instrument of the divine intelligence that governs the unpredictable forces of existence. The obsidian mirrors used by Aztec diviners were understood as earthly counterparts of Tezcatlipoca's cosmic mirror — instruments through which the divine intelligence could be accessed and consulted.
