MAP 11.1The Olmecs, ca. 1500–300 B.C.E.Olmec civilization flourished in the coastal lowlands of southern Mexico along the Caribbean coast. Olmec patterns of settlement, culture, religion, organization, and trade are known almost solely through excavation of archaeological sites.

The Olmecs were an early civilization that shaped the religion, trade practices, and technology of later civilizations in Mesoamerica. They flourished in the coastal lowlands of Mexico from 1500 to 300 B.C.E. The Olmecs formed the first cities of Mesoamerica, and these cities served as centers of agriculture, trade, and religion (Map 11.1). Through long-distance trade, the Olmecs spread their culture and technology across Mesoamerica, establishing beliefs and practices that became common to the civilizations that followed.

The Olmecs cultivated maize, squash, beans, and other plants and supplemented their diet with wild game and fish. But they lacked many other resources. In particular, they carried stone for many miles for the construction of temples and for carving massive monuments, many in the shape of heads. Across far-flung networks the Olmecs traded rubber, cacao, pottery, clay figures, and jaguar pelts, as well as the services of artisans such as painters and sculptors, in exchange for obsidian, a volcanic glass that could be carved to a razor-sharp edge and used for making knives, tools, spear tips, and other weapons.

These ties between the Olmecs and other communities spread religious practices, creating a shared framework of beliefs among later civilizations. These practices included the construction of large pyramid temples, as well as sacrificial rituals. In addition to the manner of worship, archaeologists can trace the nature of the deities common in Mesoamerica. Olmec deities, like those of their successors, were combinations of gods and humans, included merged animal and human forms, and had both male and female identities.

The Olmecs also used a Long Count solar calendar — a calendar based on a 365-day year. Archaeologists presume that the existence of the Long Count calendar meant that the Calendar Round combining the 260-day and 365-day years already existed as well. All the later Mesoamerican civilizations used at least one of these calendars, and most used both of them.
