| The Olmec flourished as the first major civilization of Mesoamerica between 1500 and 600 bc and were the first in the region to use stone for sculpture and architecture. Among other monolithic works, the Olmec carved three-dimensional stone heads, ranging in height from about 2 to 3 m (6 to 10 ft), out of basalt boulders quarried in distant mountains. Archaeologists believe the heads, all of which have similar facial features and wear helmets, are portraits of Olmec rulers. |
