In the last known largely unexcavated Maya megacity, archaeologists have uncovered the only known mural adorning an ancient Maya house, a new study says—and it’s not just any mural.
In addition to a still vibrant scene of a king and his retinue, the walls are rife with calculations that helped ancient scribes track vast amounts of time. Contrary to the idea the Maya predicted the end of the world in 2012, the markings suggests dates thousands of years beyond that.
“The paintings we have here—we’ve never found them anyplace else,” excavation leader William Saturno told National Geographic News.
And in today’s Xultún—to the untrained eye, just 12 square miles (31 square kilometers) of jungle floor—it’s a wonder Saturno’s team found the artwork at all.
