This photo shows a giant Olmec stone head from La Venta, Mexico. During the excavations in the 1940s and 1950s, 17 such heads were found, which, as expected, generated a lot of questions.
Archaeologists are still wondering how the people of that time managed to create such large and heavy statues, what tools they used and how they were able to transport the materials.
The Olmec civilization (older than the Maya) is one of the greatest enigmas in history.
Certainly the most famous of the La Venta monumental artifacts are the four colossal heads. Seventeen colossal heads have been unearthed in the Olmec area, four of them at La Venta, officially named Monuments 1 through 4.
Three of the heads—Monuments 2, 3, and 4—were found roughly 150 meters north of Complex A, which is itself just north of the Great Pyramid. These heads were in a slightly irregular row, facing north. The other colossal head—Monument 1 (shown at left) – is a few dozen meters south of the Great Pyramid.
The La Venta heads are thought to have been carved by 700 BCE, but possibly as early as 850 BCE, while the San Lorenzo heads are credited to an earlier period. The colossal heads can measure up to 9 feet 4 inches (2.84 m) in height and weigh several tons. The sheer size of the stones causes a great deal of speculation on how the Olmec were able to move them. The major basalt quarry for the colossal heads at La Venta was found at Cerro Cintepec in the Tuxtla Mountains, over 80 km away.
Each of the heads wears headgear reminiscent of 1920s-style American football helmets, although each is unique in its decoration. The consensus is that the heads likely represent mighty Olmec rulers.
