 There is an inscription that refers to the year 321 BC, but no text explains the significance of this date.An event at Copán is linked to another event that happened 208 days before in AD 159 at an unknown location that is also mentioned on a stela from Tikal, suggesting that it is a location somewhere in the Petén Basin, possibly the great Preclassic Maya city of El Mirador.This AD 159 date is mentioned in several texts and is linked to a figure known as "Foliated Ajaw".
