Olmec in the context of "2nd millennium BC"

A cradle of civilization is a location and a culture where civilization was developed independently of other civilizations in other locations. A civilization is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages (namely, writing systems and graphic arts).

Scholars generally acknowledge six cradles of civilization: Mesopotamia, Ancient Egypt, Ancient India and Ancient China are believed to be the earliest in Afro-Eurasia, while the Caral–Supe civilization of coastal Peru and the Olmec civilization of Mexico are believed to be the earliest in the Americas. All of the cradles of civilization depended upon agriculture for sustenance (except possibly Caral–Supe which may have depended initially on marine resources). All depended upon farmers producing an agricultural surplus to support the centralized government, political leaders, religious leaders, and public works of the urban centers of the early civilizations.

San Lorenzo Tenochtitlán or San Lorenzo is the collective name for three related archaeological sites—San Lorenzo, Tenochtitlán and Potrero Nuevo—located in the southeast portion of the Mexican state of Veracruz. Along with La Venta and Tres Zapotes, it was one of the three major cities of the Olmec, and the major center of Olmec culture from 1400 BCE to 900 BCE. San Lorenzo Tenochtitlán is best known today for the colossal stone heads unearthed there, the greatest of which weigh 28 metric tons (28 long tons; 31 short tons) or more and are 3 metres (9.8 ft) high.

The site is not to be confused with Tenochtitlan, the Aztec capital located within Mexico City. Administrative names were translated into Aztec/Nahuatl and spread alongside Catholic names during the European conquest, replacing any original locality names, as the original Olmec name was lost.

La Venta is a pre-Columbian archaeological site of the Olmec civilization located in the present-day Mexican state of Tabasco. Some of the artifacts have been moved to the museum Parque-Meseo La Venta [es], which is in nearby Villahermosa, the capital of Tabasco.

The Olmec colossal heads are stone representations of human heads sculpted from large basalt boulders. They range in height from 1.17 to 3.4 metres (3.8 to 11.2 ft). The heads date from at least 900 BCE and are a distinctive feature of the Olmec civilization of ancient Mesoamerica. All portray mature individuals with fleshy cheeks, flat noses, and slightly-crossed eyes; their physical characteristics correspond to a type that is still common among the inhabitants of Tabasco and Veracruz. The backs of the monuments are often flat.

The boulders were brought from the Sierra de Los Tuxtlas mountains of Veracruz. Given that the extremely large slabs of stone used in their production were transported more than 150 kilometres (93 mi), requiring a great deal of human effort and resources, it is thought that the monuments represent portraits of powerful individual Olmec rulers. Each of the known examples has a distinctive headdress. The heads were variously arranged in lines or groups at major Olmec centres, but the method and logistics used to transport the stone to these sites remain unclear. The heads all display distinctive headgear and one theory is that these were worn as protective helmets, maybe worn for war or to take part in a ceremonial Mesoamerican ballgame.

San Bartolo is a small pre-Columbian Maya archaeological site located in the Department of Petén in northern Guatemala, northeast of Tikal and roughly fifty miles from the nearest settlement. San Bartolo's fame derives from its splendid Late-Preclassic mural paintings still heavily influenced by Olmec tradition and from examples of early Maya script.
