When archaeologists found a tunnel under Mexicos birthplace of the gods, they could only dream of the riches they would discover. Now its wonders from jewel-eyed figures to necklaces of human teeth are being revealed to the world
In 2003, a tunnel was discovered beneath the Feathered Serpent pyramid in the ruins of Teotihuacan, the ancient city in Mexico. Undisturbed for 1,800 years, the sealed-off passage was found to contain thousands of extraordinary treasures lying exactly where they had first been placed as ritual offerings to the gods. Items unearthed included greenstone crocodile teeth, crystals shaped into eyes, and sculptures of jaguars ready to pounce. Even more remarkable was a miniature mountainous landscape, 17 metres underground, with tiny pools of liquid mercury representing lakes. The walls of the tunnel were found to have been carefully impregnated with powdered pyrite, or fools gold, to give the effect in firelight of standing under a galaxy of stars.
The archaeological site, near Mexico City, is one of the largest and most important in the world, with millions of visitors every year. This was its most exciting development for decades and the significance of these new discoveries is explored in a major exhibition opening this month at the de Young Museum in San Francisco.
