I’ve written several stories about Teotihuacan, and now I’m writing another one. Researchers studying a tunnel beneath the pyramid known as the “Temple of the Feathered Serpent” discovered hundreds of metallic spheres. The significance of these balls, carved from pyrite, is unknown, but the tunnel was believed to have been used by priests and/or rulers for secret rituals.
Archaeologists initially used robots equipped with laser scanners and infrared cameras to explore parts of the tunnel that had not been previously excavated. Now they plan to excavate the remainder of the tunnel and adjoining chambers. They believe important artifacts are awaiting discovery along with the gold-colored spheres. The tunnel has lain undisturbed for about nearly 2,000 years.
The city of Teotihuacan was already abandoned when it was first discovered by the Aztec, who called it the City of the Gods. It has been slow to give up its secrets, partly because no writing system has been discovered there, which is odd considering the high level of organization required to construct and govern it. No one knows who built thecity, which is believed to have been a major cultural and trading center.
