A 2,000-year-old green serpentine stone mask was found at the base of the Pyramid of the Sun in Teotihuacan, Mexico.
It’s believed that these offerings were left as part of a ritual to inaugurate the construction of the pyramid, hence its location at the lower level. The mask itself is extremely lifelike, which gave rise to the theory that it’s actually a portrait. This would be incredible, as archaeologists have little information about the people who constructed Teotihuacan. There are also conflicting theories about the exact use of the pyramid. Even the name isn’t original.
