Olmec Heads, Mexico

900 BCE

On a sweltering day in 1862 at the foot of the Tuxtla Mountains in the Mexican state of Veracruz, a farmworker was clearing a cornfield when he hit something hard and smooth lodged in the earth. He thought it was the rounded base of an iron cauldron buried upside down, and, it being the 1860s, he reported the find to the owner of the hacienda where he worked. The farmworker’s boss told him to dig up the cauldron immediately and bring it to him. As the farmworker labored to uncover the object, he realized he had found not a large iron bowl, but a gargantuan stone sculpture with a pair of glaring eyes, a broad nose, and a downturned mouth. What had appeared to be the base of a cauldron was actually the top of a helmet worn by the glowering figure. What the farmworker had unearthed was a colossal Olmec head, one of the first clues to the existence of that ancient culture.
