La Mojarra Stela 1: Epi-Olmec Writing and a Warrior King

La Mojarra Stela 1 is a carved basalt monument from southern Veracruz, Mexico, bearing the longest known text in the Epi-Olmec, or Isthmian, script. Its two Long Count dates correspond to AD 143 and AD 156, and its portrait shows a ruler in an elaborate costume. Found in a river in 1986, it sparked one of the most debated decipherment claims in Mesoamerican studies.

Background: after the Olmecs

The Olmec civilization flourished on the Gulf Coast of Mexico from about 1600 BC to 400 BC. After the decline of centres such as La Venta, the region did not empty. Its later culture, from roughly 300 BC to AD 250, is called Epi-Olmec, meaning “after the Olmec”.

Epi-Olmec sites such as Tres Zapotes and Cerro de las Mesas produced some of the earliest dated monuments in the Americas, using the Long Count calendar. This calendar counted days from a mythical starting point in 3114 BC and was later used extensively by the Maya.

Discovery

In 1986 the stela was found lying in the Acula River near the village of La Mojarra, in the lowlands of southern Veracruz. It had probably been moved or had fallen into the water long after it was carved. The monument was taken to the Museo de Antropología de Xalapa, where it remains.

The Mexican archaeologist Fernando Winfield Capitaine published the first description in 1988. Scholars quickly realised that it carried by far the longest text in a script previously known only from a few short inscriptions.

The monument

The stela is roughly 2.3 metres high and 1.4 metres wide, and weighs around 4 tonnes. Its main face shows a standing man wearing a towering headdress with a bird or monster mask, ear ornaments and a decorated belt. He is usually interpreted as a ruler.

Around and beside him run vertical columns of glyphs, including the two Long Count dates, usually transcribed as 8.5.3.3.5 and 8.5.16.9.7. In the modern calendar these correspond to May of AD 143 and July of AD 156. More than 500 glyphs survive, though part of the surface is worn or damaged.

The thirteen-year gap between the dates suggests that the text covers events in the ruler’s career rather than a single moment. The combination of a large royal portrait with a long dated text resembles later Maya stelae, and many scholars see Epi-Olmec monuments as part of the shared background from which Maya royal monuments developed.

The decipherment debate

In 1993 the linguist Terrence Kaufman and the epigrapher John Justeson published a proposed decipherment in the journal Science. They argued that the script recorded an early form of a Zoquean language, part of the Mixe-Zoquean family still spoken in southern Mexico.

According to their reading, the text describes the rise to power of a ruler they called “Harvester Mountain Lord”, his rituals, a lunar eclipse, a battle and the deeds of his kin. The reading was detailed and widely discussed.

In 2003 Stephen Houston and Michael Coe tested the system on a short Isthmian text on a mask of unknown provenance. They reported that the proposed values did not produce a meaningful reading. Most specialists today regard Isthmian writing as only partly understood, with dates and some signs read, but the language content uncertain.

Other Isthmian texts

The script is known from only a handful of objects. The best-known besides La Mojarra Stela 1 is the Tuxtla Statuette, a small jade figure with a Long Count date corresponding to AD 162. Other short texts appear on stone and ceramic objects from Veracruz and neighbouring areas.

With so few examples, the stela is crucial. It allows researchers to study the order of signs, repeated phrases and the link between text and image. It may also show how early Mesoamerican rulers used writing and dated monuments to display legitimacy.

Myths and facts

Myth: The stela proves that the Olmecs invented writing. Fact: It was carved centuries after the Olmec heyday, by their Epi-Olmec successors. Earlier possible writing, such as the Cascajal Block, is debated separately.

Myth: The stela has been fully translated. Fact: A full decipherment was proposed but has not been accepted by most epigraphers.

Timeline

• c. 300 BC – AD 250: Epi-Olmec culture flourishes on the Gulf Coast.
• AD 143 (May): First Long Count date recorded on the stela.
• AD 156 (July): Second, later Long Count date on the stela.
• AD 162: Date recorded on the Tuxtla Statuette.
• 1986: The stela is found in the Acula River at La Mojarra.
• 1993: Justeson and Kaufman publish their decipherment in Science.
• 2003: Houston and Coe publish a test that challenges the decipherment.

Why it matters

La Mojarra Stela 1 is one of the longest early texts from the Americas and a window on writing outside the better-known Maya tradition. Whether or not it is ever fully read, it shows that Gulf Coast societies were recording dates, rulers and events in the second century AD.
