Olmec Civilization: Mesoamerica's Mother Culture Explained

Introduction to the Olmec Civilization

Long before the Maya, Aztec, or Toltec flourished in Central America, there lived the Olmecs — a civilization that has continued to intrigue and amaze the world. They were the most prevalent group in Mesoamerica and a highly developed, well-organized society with a complex calendar and hieroglyphic writing system. The Olmecs are widely regarded as the mother civilization of Mesoamerica.

The Olmecs lived in the areas of La Venta in Tabasco, San Lorenzo Tenochtitlan, and Laguna de los Cerros in Veracruz during the pre-classic period. They built their cities around a central raised mound. These mounds, used for religious ceremonies, were replaced with pyramid-shaped structures around 900 B.C. The Olmecs used basalt, quarried from the Tuxtla Mountains, to construct plazas and religious pyramid structures. Houses were made of wooden walls with clay and palm rooftops, and a hierarchical society separated the elite from the common groups in residential areas. Crop production was made possible through an irrigation system the Olmecs built throughout their cities. They supplemented crops by hunting and by accessing waterways for fishing and trading with surrounding cultures.

Olmec Society, Religion, and Daily Life

Because the Olmecs used animals as powerful symbols of religion, it is widely accepted that they practiced shamanism, believing that each person possessed an animal spirit. It is also believed that hallucinogenic substances derived from the marine toad were used by shamans to induce trances. The elite and nobles were buried ceremoniously with jewels in plazas constructed with jade walls.

Beginning around 1200 B.C., Olmec influence spread as far as what are now the modern nations of Guatemala, Honduras, Belize, Costa Rica, and El Salvador. After creating a culture that would later be adapted by all the Mesoamerican civilizations that followed, the Olmecs disappeared around 300 B.C. Because even their bones have long since decomposed in the humid rainforest, everything scholars know about them is based on the remains of cities and on comparisons to later civilizations. There are therefore numerous theories concerning Olmec origins, social structure, and religion. What is generally accepted among scholars is that the Olmecs' ancestors, "like those of all Native Americans, were Asian hunter-gatherers who crossed into the Americas at least 12,000 years ago, at the end of the most recent ice age." From bits of ancient refuse and remnants of mud buildings, it is concluded that around 2000 B.C., descendants of these original groups had settled in small fishing villages along the rivers of what is now the Mexican states of Veracruz and Tabasco.

Olmec Art and the Colossal Stone Heads

The Olmecs are known for their unique artistic creations, most notably their colossal head sculptures. The majority of these heads were either decapitated or destroyed in some way by the Olmecs themselves after a ruler died, apparently as a sacrifice to the gods or animal spirits. Most of the heads bear deformed features — a ritual practice carried out at birth for noble children, much as was done in Mayan culture. Other recurring motifs in Olmec art include jaguars, serpents, and monkeys.

Because of its repetition across art forms, the jaguar is clearly regarded as a supernatural creature, and the intertwining of human and animal figures reflects a religious belief in the connection between the two worlds. Jade was the preferred material for most art sculptures, as it was for the plaza walls. Notably, jade was not a natural stone found in the Olmec heartland, indicating that the Olmecs maintained extensive trade networks.

What is unanimously agreed upon by art historians and archaeologists is that the Olmecs produced the earliest sophisticated art in Mesoamerica and that their distinctive style provided a model for the Maya, Aztec, and other later civilizations in the region. Peter David Joralemon of Pre-Columbian Art Research Associates explains that prior to 900 B.C., small Olmec objects tend to be ceramic, whereas later pieces were commonly made from jade and serpentine — rare materials that required skilled artisans to carve.

Most Olmec artifacts are sculptures and figurines, decorated stone stelae, votive axes, altars, and similar objects, some of which were polished to a mirror-like shine. From the earliest period, human figures wear simple costumes, while later figures are more elaborate. Ceramics were relatively simple sculptures, while jade pieces tend to have been made for rulers to wear. As Joralemon explains, "They were clearly a display of personal wealth, an indication of status and prestige" — evidence that Olmec society may have been growing increasingly stratified. Recurring images include birds, dwarfs, hunchbacks, dragons, and most importantly the "were-jaguar" — part human, part jaguar — indicating a strong belief in the supernatural world and shamanism. Although archaeologists have found a variety of household objects, most are broken, and as Joralemon notes, "we know relatively little about the common Olmec."

The most famous of all Olmec artifacts are seventeen colossal stone heads, probably representations of rulers, thought to have been carved between 1200 and 900 B.C. from blocks of volcanic basalt. The heads range from five to eleven feet in height and weigh up to twenty tons. Scholars do not know how the Olmecs transported the basalt from quarries some eighty miles away to the top of a plateau roughly 150 feet high. As Joralemon observes, "It must have been an incredible engineering effort — these people didn't have beasts of burden, and they didn't have wheels. We don't know if they floated the blocks on rafts or traveled over land."

Origins, Social Structure, and Political Organization

Olmec expert Richard Diehl has stated that by around 2000 B.C., "we know that they had adapted to the environment," supplementing "their diet with cultivated plants — maize and beans — they became more and more dependent on agriculture, perhaps because the population was increasing." However, archaeologists do not know what caused a society of farmers to evolve into a class-based social structure, with "leaders and commoners, bosses and laborers, artisans and priests." Diehl believes that population pressure was a key factor: as pre-Olmec villages grew, they stratified. "A new elite class probably asserted its leadership through charisma, control of trade networks and control of people, all of which led to the evolution of a complex society and, eventually, the art style we call Olmec." Whether this theory is accurate is debatable; nonetheless, by 1200 B.C., Olmec society was flourishing on a fertile plain overlooking the Chiquito River at San Lorenzo.

By comparison, Olmec sites such as San Lorenzo are far less impressive than the Mayan cities of the Yucatan peninsula, partly because Olmec sites supported only a few thousand people compared to Mayan sites of 100,000 or more. The sites were also built on a more modest scale: the Great Pyramid at La Venta, built around 800 B.C., is only about 100 feet high — roughly half the height of the tallest Mayan pyramid at Chichen Itza. Yet the Olmecs laid out each site "according to a preconceived plan, a fact that reflects both the people's religious beliefs and a fairly sophisticated knowledge of engineering," as demonstrated by the mounds at La Venta, which are oriented exactly eight degrees west of north.

According to Ann Cyphers, an Olmec scholar at Mexico's National Autonomous University, the San Lorenzo site shows evidence of a class structure, "with more elaborate housing for the upper classes and simpler accommodations for the middle class and the poor — workshops for producing artifacts, and irrigation and drainage systems — all these things show a society of great complexity."

However, that complexity did not extend to Olmec politics. Diehl explains that instead of a single unified state, the Olmec were a collection of chiefdoms: "There were probably a number of different populations, forming groups that rose and fell over time and shifted alliances. I don't think there was any political integration." Furthermore, no one knows whether the major cities — San Lorenzo, La Venta, and Tres Zapotes — traded with one another or even co-existed peacefully.

There is still hope that scholars will be able to solve many of the unanswered questions surrounding the Olmecs, since most sites have barely been studied due to annual floods that coat the land with thick layers of silt that dry into impenetrable clay. According to Diehl, approximately eighty percent of the entire Olmec territory in southern Mexico has been converted from jungle to cow pasture and sugar-cane fields over the last twenty years. "There's so much vegetation on the surface that you can't just pick up pottery. Generally, you can't even see the ground," and the hot, humid climate makes fieldwork very difficult. Nevertheless, during the last decade, researchers have uncovered a number of key sites, including the monument-strewn ruins of Teopantecuanitlan in Guerrero and the sacred shrine at El Manati, whose murky springs yielded the first examples of wooden Olmec statuary and the earliest known evidence of child sacrifice in Mesoamerica.

Conclusion: The Enduring Influence of the Olmecs

Although the Olmecs are perhaps the least known of the lost civilizations, it is clear that their culture played an intricate part in the development of the peoples who followed them into the valley. The Olmecs enabled the Maya, Toltec, and eventually the Aztec to establish organized societies with defined class structures and political systems. Due to Olmec achievements in masonry and agriculture, great pyramids, palaces, and temples dot the Latin American landscape, along with canals, bridges, and irrigation systems traceable to these ancient cultures. Through the Olmecs, later civilizations were able to expand upon inherited knowledge of timekeeping and writing, creating sophisticated and complex calendar systems. Traces of the rubber ball games first innovated by the Olmecs can be found throughout the cultures that followed them. In fact, the Maya, Toltec, and Aztec owe much of their success and cultural flourishing to this ancient people, who first ventured into the region some three thousand years ago and left the world a wealth of enduring civilization.
