    Using modern technology, archaeologists (考古学家) have recently discovered about 200 Mayan artifacts (玛雅古器) in Mexico, which surprisingly, appear to have been untouched for up to 1,000 years. The artifacts were found inside a cave in ruins of the ancient Mayan city of Chichen Itza on Mexico’s Yucatan Peninsula.

The lead researcher on the project is Mexican archaeologist Guillermo de Anda. He called the cave a “scientific treasure”.

The findings included bone pieces and burnt offering materials. In addition, incense burners, vases, plates and other objects were discovered. Some items included the portrait of Tlaloc, the rain god of central Mexico.

The cave where the objects were found is so unique. It is part of a cave system known as Balamku. The cave is long, narrow and dark. It is about three kilometers east of the main pyramid of Kukulkan. It sits at the center of Chichen Itza which is the stone city described by the United Nations as “one of the greatest Mayan centers of the Yucatan Peninsula.”

The cave sits about 24 meters underground, with areas connected by passages. Some of the passages were so narrow that researchers had to climb in or pull themselves through. The team has so far explored about 460 meters of the cave, and is unsure how far it stretches. The team plans to continue exploring the cave. The found artifacts will not be removed, but studied inside.

The team accidentally found the artifacts while exploring Chichen Itza in an effort to learn more about its underground water system. The new discovery will help scientists better understand the history, culture, lives and beliefs of people who lived in Chichen Itza, especially in the boom years.

Archaeologists believe there may be another cave hidden under the pyramid of Kukulkan that could be connected to the latest find. “Let’s hope God will lead us there,” Guillermo de Anda said. “That is part of the reason why we are entering these sites to find a connection to the natural well under the Kukulkan.”
