Archaeologist William Saturno said Tuesday he was awe-struck when he uncovered a Maya mural not seen for nearly two millennia. Discovered at the San Bartolo site in Guatemala, the mural covers the west wall of a room attached to a pyramid, Saturno said at a briefing.

In brilliant color, the mural tells the Maya story of creation, he said. It was painted about 100 B.C., but later covered when the room was filled in.
