38. Mayan Calendars

Historians have identified at least two Mayan calendars, but they have not been reliably linked to a modern calendar.

The context of Mayan records is conjectural. At one time dates and other text inscribed on monuments were thought to log astronomical observations, but current translations treat them mostly as mundane history chronicling the exploits of kings. Whatever the case, the full import of Mayan astronomy has yet to be revealed.
