AN UPDATE ON THE MASS GRAVE UNDER THE PYRAMID 0F THE SUN

January 15, 2022

Archaeologist Sergio Gomez uncovered the tunnel under the Pyramid of the Sun in 2017. Among other finds, he uncovered 20 human skeletons arranged in a symbolic pattern.
Another 260 bodies were found to be built unto the fabric and foundation of the building.

They may have been sacrificed to the gods, or simply died of natural causes. Gómez and his team had to remove 1,000 tonnes of soil in order to access the tunnels. They believe the Aztecs likely deposited the dirt as a way to seal off any access points.

This meant that most of the artifacts found were largely undamaged and untouched by robbers. His team found more than 100,000 objects along the tunnel, 
The artefacts included a greenstone crocodile teeth, crystals shaped into eyes, as well as sculptures of jaguars.

And, the tunnel itself was lined in iron pyrite, it reacted to any light by shimmering like the night sky, a reaction likely purposefully induced by the Aztecs in order to replicate the stars.
