Autochthon (ancient Greece)

In ancient Greece, the concept of autochthones (from Ancient Greek αὐτός autos "self," and χθών chthon "soil"; i.e. "people sprung from earth itself") means the indigenous inhabitants of a country, including mythological figures, as opposed to settlers, and those of their descendants who kept themselves free from an admixture of colonizing entities.

In mythology, autochthones are those mortals who have sprung from the soil, rocks and trees. They are rooted and belong to the land eternally.
