This episode looks at the Maya civilization and their advanced knowledge of mathematics and time-keeping. It presents theories as to why the Maya backdated the 5125-year long-count calendar to 3114 BC (over 3,000 years before their civilization began), and what could happen after it ends December 21, 2012. Discussed are two artifacts, Tortuguero monument six, and a Comalcalco mud brick that may suggest the return of a star god Bolon Yokte; the Popol Vuh creation myths; the Chilam Balam manuscripts; and the monuments of Tikal (which is suggested to have been built to mimic the Pleiades cluster) and Chichen Itza dedicated to the return of the Maya god Kukulkan.
