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 suggest dates thousands of years in the future.
