I add some properly Latin American myths and mythological characters, whose importance commonly extends beyond the borders of a single country. Unpretentious to be exhaustive, only as a first approach.
✔️ Pachamama (myth of the indigenous peoples of the Andes mountains)
✔️ The myth of the original Selk’nam matriarchy (Tierra del Fuego)
✔️ The civilizing hero Bochica (Muisca Civilization)
✔️ The myth of Viracocha (Inca Empire)
✔️ The Popol Vuh (as Stephen said)
✔️ The solar God Huitzilopochtli (Mexica Culture)
✔️ The Tupi Guarani myth of the “Land without Evil”
Its importance is capital, since each of them expresses a particular worldview, ranging from the relationship with the earth to human relationships and the link with transcendence.
