Maya mythology
As Olmec mythology has left no documents comparable to the "Popol Vuh" from Maya mythology, any exposition of Olmec mythology must be based on interpretations of surviving monumental and portable art (such as the "Señor de Las Limas" statue at the Xalapa Museum), and comparisons with other Mesoamerican mythologies. Olmec art shows that such deities as Feathered Serpent and a rain supernatural were already in the Mesoamerican pantheon in Olmec times.
