MEXICO CITY (AFP) ― Mexican archeologists on Tuesday announced the discovery of 23 stone plaques with carved images inside the main temple of what was once the Aztec capital of Tenochtitlan, in downtown Mexico City.

The carved images of serpents and warriors tell stories that include the birth of the Aztec warrior god Huitzilopochtli, the National Institute of Anthropology and History (INAH) said.

The tiles were likely carved when the main temple was built between 1440 and 1469, said archeologist Raul Barrera.

It is the first time that archeologists discover stone carvings set up explicitly to narrate an Aztec myth within the ancient city’s most sacred temple, the statement read.

The tiles on average measure 50 centimeters by 40 centimeters.
