The People

People

Aztecs (Mexica)

Region

Central Mexico

Period

14th – 16th c.

The Aztec gods were worshipped by the Mexica people from their capital, Tenochtitlan, in central Mexico. They believed the sun would only move if fed with blood, which led to the famous sacrifices atop pyramid-temples. Their world was cut short by the Spanish conquest in the 16th century.

The 18-month ritual calendar brought festivals such as Toxcatl, in which a youth lived for a year as the embodiment of Tezcatlipoca. Every 52 years, the New Fire Ceremony extinguished every flame in the empire, rekindled from a single bonfire to prevent the end of the world.

At a glance

Tlaltecuhtli (in classical Nahuatl orthography Tlāltēuctli, literally 'Lord of the Earth', often treated as 'Lady of the Earth' because of her attributes of gestation and birth) is the colossal primordial Mesoamerican deity of the earth's crust, the personification of the living soil, of the telluric depths and of the voracious womb that devours corpses to regenerate biological life. According to the cosmogonic myth recorded in the sixteenth-century French manuscript Histoyre du Mechique, before the present universe was ordered there existed an amphibious, formless being that swam in the primordial waters, provided with sharp fangs and devouring mouths at every joint of the elbows, knees and hips. To establish a stable world, the demiurgic gods Quetzalcoatl and Tezcatlipoca descended in the form of giant serpents, seized the monster by its four limbs and split its body in two: with the upper half they raised the celestial vault, and with the lower half they consolidated the firm land. Moved by her suffering, the gods shaped the vegetation from her hair, the rivers and caves from her jaws and the mountains from her features, yet the wounded monster continued to moan in the dark nights, demanding the blood of sacrifices to sate her open mouths and to grant maize and harvests to human beings.

Name and epithets

Morphologically, the Nahuatl theonym Tlāltēuctli joins the noun tlālli ('earth', 'soil' or 'terrestrial surface') to the lordly title tēuctli ('noble', 'lord' or 'ruler'), designating strictly the 'Lord of the Earth'.

In the ancient sources

Histoyre du Mechique (Fray Andrés de Olmos and André Thevet), c. 1543 CE. Contains the foundational narrative of the dismemberment of the primordial sea monster by the two serpents Quetzalcoatl and Tezcatlipoca.

The myths

The Primordial Battle in the Ocean and the Cosmic Dismemberment. As preserved in chapter VI of the Histoyre du Mechique, in the chaotic beginnings of the world before the creation of earth and sky, the monstrous goddess…

Worship and archaeology

The cult of Tlaltecuhtli was distinguished by the invisibility of her representations in public spaces and by the liturgical intensity of her underground rites.

How the god was depicted

The monumental iconography of Tlaltecuhtli is dominated by a monstrous, androgynous figure in a squatting birth posture (in tlacatiliztli), with knees bent and arms raised at right angles.

What scholars debate

The Dilemma of Gender: Masculine, Feminine or Androgynous Entity?. The gender status of Tlaltecuhtli is one of the most discussed topics in Mesoamerican archaeology.

After antiquity

Since the striking discovery of its monolith in the historic centre of Mexico City, Tlaltecuhtli has become the foremost emblem of Mesoamerican archaeological heritage in the twenty-first century.

Did you know?

The Tlaltecuhtli monolith discovered in 2006 weighs more than 12 tonnes and measures about 4.19 by 3.62 metres, making it the largest intact Mexica sculptural piece recovered by modern scientific archaeology.
