A robot will soon begin exploring the last stretch of a tunnel found at the archaeological site of Teotihuacan in central Mexico, the third time anywhere in the world that such an automaton is used to design excavation strategies.
The tunnel, discovered under the Temple of the Plumed Serpent, or Quetzalcoatl, is believed to lead to a chamber almost 2,000 years old, probably a place where dignitaries of the pre-Columbian city received their investiture or were buried, the National Anthropology and History Institute, or INAH, said.
So far, INAH has found approximately 60,000 pieces of artifacts and pottery throughout the excavation, and they theorize that the tunnel could lead them to where the remains of rulers of the ancient city may have been laid to rest. According to archaeologist Sergio Gomez, “every day our expectations are increasing”. It’s known that rulers were buried in the holiest places. “For a long time local and foreign archaeologists have attempted to locate the graves of the rulers of the ancient city, but the search has been fruitless.”
