Seers of the Heavens -- The Maya

Synopsis
The Maya civilization, which flourished for 2,000 years in Central America, developed a sophisticated understanding of astronomy. Without the use of telescopes, or even the metal to build them, the Maya unlocked the mysteries of the movements of the heavens, and developed a very precise solar calendar that was "not off a day in 4,000 years." Some people say the Maya predicted the end of the world as we know it in 2012. This episode uses new investigations of Maya ruins and recent breakthroughs in deciphering their hieroglyphics to reveal the astronomical secrets of this great civilization.
