Xiuhcoatl

Also Known As: Classical Nahuatl *xiuhcōātl*, from *xihuitl*, “turquoise, grass, year,” and *cōātl*, “serpent”; commonly rendered “turquoise serpent” or “fire serpent”; plural *xiuhcocoah*
Region/Culture: Mesoamerica and the Caribbean
Mythos: Aztec Mythology
Primary Type/Nature: Elementals
Mythical Attributes: A serpent of solar fire that functions as a weapon, a back ornament and the animal form of the fire god, carrying drought, flame and the turning of the year in its body.
Role in Mythos: It is the weapon Huitzilopochtli used at Coatepec to destroy Coyolxauhqui and rout the Centzon Huitznahua, and the instrument by which the sun drives off the moon and stars.
Relation to Humans: Mortals did not petition the fire serpent directly; they wore it, carved it and built it out of paper, and the Mexica royal diadem was understood to reproduce its tail. Its yearly appearance at Panquetzaliztli, made of paper and red feathers and then burned, put the sun’s weapon briefly into human hands.

Among the rubble under Mexico City, a broken disk of stone carries a killing. On it a woman lies fallen, and driven through her chest at an angle is a serpent with its snout curled backward, its body ridged into segments, its tail flaring into a sign that meant a year. The woman is Coyolxauhqui. The serpent is the Xiuhcoatl, and the fragment is the closest thing the Mexica left to a photograph of the moment their patron god came into the world swinging.

The name splits cleanly and then refuses to settle. *Cōātl* is serpent, plainly enough. *Xihuitl* is the trouble: it means turquoise, and it means grass, and it means year, and in central Mexico in the centuries before the Spanish arrived all three of those ideas sat close to fire. Turquoise for the blue heart of a flame and the blue-green stone the fire god wore. Grass for the dry season, when the plateau turns the colour of straw and catches at a touch. Year for the sun’s slow circuit and the heat it drags behind it. So Xiuhcoatl is the turquoise serpent, and it is also the fire serpent, and the two readings were never in competition.

In Mexica art the creature is unmistakable. The snout turns sharply back on itself, like a nose pushed the wrong way. The body is segmented along its length, a stacked run of bands rather than a smooth rope of muscle. Short legs end in claws, which no rattlesnake on the plateau has ever had. Knotted strips of paper wind round the body, the same paper the Mexica soaked in blood and burned in offering, so the serpent carries the signature of sacrifice on its skin. And the tail, always the tail, opens into the trapeze-and-ray sign that stood for the year, sometimes marked as well with the glyph for grass. A stone figure of it now in London, carried out of Mexico in 1823 by the showman William Bullock and reported by an earlier collector to have come from Texcoco across the lake, shows every one of these elements in basalt, the claws still crisp.

Where it came from is genuinely unclear. The trail runs back at least to Tula in the Early Postclassic, and behind that, in the Classic period, to Teotihuacan, whose War Serpent already wore the grass symbol, the flames and the trapeze-and-ray year sign. Whether that creature is the same one under an older name, or a different animal that lent its parts, has not been settled. What is clear is that by the time of Tenochtitlan the fire serpent had become an instrument, and instruments have owners.

The story that made it famous is told in the third book of Sahagún’s great compilation, gathered from Nahua elders in the decades after the conquest. On Coatepec, the serpent mountain, Coatlicue was sweeping when a ball of down drifted onto her and left her pregnant. Her daughter Coyolxauhqui took this as an outrage and led her four hundred brothers, the Centzon Huitznahua, up the mountain to kill their mother. They arrived too late. Huitzilopochtli came out of Coatlicue fully grown and already armed, and the weapon in his hand was the Xiuhcoatl. He struck Coyolxauhqui with it and she came apart on the slope, and the four hundred he scattered and chased and mostly destroyed. Read one way this is a war story. Read another it is sunrise, the sun coming up over the ridge and putting out the moon and every star at once.

Most of the time, though, the fire serpent was not being thrown at anyone. It was being worn. Both Xiuhtecuhtli, the old lord of fire, and Huitzilopochtli appear in the codices with a xiuhcoatl fixed across the shoulders as a back device, the tail sign riding high behind the head, the paper strips lifting whenever the figure moved. For Xiuhtecuhtli the relationship went further than costume. The serpent was understood as his nahual, the animal shape a person or a god slips into, which makes the fire serpent less an object the fire god owns than a version of him that can be picked up and swung.

It also kept company in a very particular arrangement. Page 46 of the Codex Borgia shows four of them, smoking, set around a burning turquoise mirror. A mirror rimmed in turquoise found far to the east at Chichen Itza has four fire serpents running round its edge. At Tula the warrior columns on Mound B carry mirrors on their backs, and around those mirrors, again, four serpents. Four fire serpents and a disk of polished stone that catches light: the pattern held across centuries and across cultures that were not otherwise speaking with one voice.

Once a year the thing was built and burned. During Panquetzaliztli, the festival of Huitzilopochtli, a Xiuhcoatl was made of paper with red feathers pouring from its open mouth to stand for flame, and it was carried through the ceremony, and a serpent dance was performed, and the torches held up that night meant the same creature. A god’s weapon reduced to paper and feathers and then set alight, which is either a diminishment or exactly the point.

What it does is simple and total. It carries fire, and fire in this system is not merely hot. It is the year turning, the drought that cracks the ground, the light that empties the sky of stars each morning. Tonatiuh, the sun, was said to be guided across the sky by the fire serpent and to use it against the enemies that came at him from below, against the stars and the moon. It pierces. It burns. Nothing in the surviving record survives being hit by it. The Mexica made it political as well: the royal diadem, the *xiuhuitzolli* or pointed turquoise thing, is understood to reproduce the serpent’s tail, so that every ruler crowned in Tenochtitlan wore the tip of the sun’s weapon on his forehead. A carved xiuhcoatl now at Dumbarton Oaks bears the year Two Reed together with the name glyph of Moteuczoma, tying the creature to the New Fire ceremony of 1507 and to the man who ordered it.

Its limits are stranger than its powers. The Xiuhcoatl has no parents, no consort, no temple of its own and no story in which it is the one who wants something. It never speaks. Every surviving account has it in another’s grip or strapped to another’s back, aimed, worn, drawn, or assembled out of paper for a single night. It cannot act alone, and nothing in the sources suggests anyone ever thought it might. That is the peculiar shape of it: a creature with a face and claws and a name of its own, which the Mexica nevertheless chose to carve, again and again, at the exact moment somebody else was using it.

Frequently Asked Questions

What is the Xiuhcoatl?

The Xiuhcoatl is the Aztec fire serpent, a mythological snake of solar fire that served as a weapon, a ceremonial back ornament and the spirit form of the fire god Xiuhtecuhtli. Its name comes from the Nahuatl words for serpent and for turquoise, grass and year, three ideas the Mexica associated with fire. It appears constantly in Aztec sculpture and in the painted codices.

What did Huitzilopochtli do with the Xiuhcoatl?

Huitzilopochtli used the Xiuhcoatl as his weapon immediately after his birth on the mountain of Coatepec. He struck his sister Coyolxauhqui with it and destroyed her, then scattered and killed most of his four hundred brothers, the Centzon Huitznahua. A broken stone disk from the Great Temple of Tenochtitlan shows the fallen Coyolxauhqui with the fire serpent driven through her chest.

What does the Xiuhcoatl look like?

The Xiuhcoatl is shown with a sharply back-turned snout, a segmented body, and short legs ending in claws, which no real snake has. Knotted strips of sacrificial paper are wound around its body, and its tail takes the form of the trapeze-and-ray sign that the Mexica used to mean a year. It is sometimes marked additionally with the glyph for grass.

Is the Xiuhcoatl a god?

The Xiuhcoatl is not worshipped as a deity in its own right, and no myth gives it parents, a consort or a temple. It was regarded as the nahual, or animal spirit form, of the fire god Xiuhtecuhtli, and it always appears in the sources being carried, worn or wielded by another figure. That subordinate role is a defining feature rather than a gap in the record.

Why was the Xiuhcoatl important to the Aztec rulers?

The fire serpent became a political emblem as well as a religious one. The Mexica royal diadem, the xiuhuitzolli, is understood to represent the tail of the Xiuhcoatl, meaning that every crowned ruler of Tenochtitlan wore a piece of the sun’s weapon. A carved Xiuhcoatl at Dumbarton Oaks links the creature directly to Moteuczoma and to the New Fire ceremony of 1507.
