Archaeologists have deciphered over 15 pre-Columbian distinct writing systems from mesoamerican societies. the ancient Maya had the most sophisticated textually written language, but since texts were largely confined to the religious and administrative elite, traditions were passed down orally. oral traditions also prevailed in other major indigenous groups including, but not limited to the Aztecs and other Nahuatl speakers, Quechua and Aymara of the Andean regions, the Quiché of Central America, the Tupi-Guaraní in today's Brazil, the Guaraní in Paraguay and the Mapuche in Chile.
