On a coastal flood plain etched by rivers flowing through swamps and alongside fields of maize and beans, the people archaeologists call the Olmecs lived in a society of emergent complexity. It was more than 3,000 years ago along the Gulf of Mexico around Veracruz.
The Olmecs, mobilized by ambitious rulers and fortified by a pantheon of gods, moved a veritable mountain of earth to create a plateau above the plain, and there planted a city, the ruins of which are known today as San Lorenzo. They left behind palace remnants, distinctive pottery and art with anthropomorphic jaguar motifs. Most impressive were Olmec sculptures: colossal stone heads with thick lips and staring eyes that are assumed to be monuments to revered rulers.
The Olmecs are widely regarded as creators of the first civilization in Mesoamerica, the area encompassing much of Mexico and Central America, and a cultural wellspring of later societies, notably the Maya. Some scholars think the Olmec civilization was the first anywhere in America, though doubt has been cast by recent discoveries in Peru.
