Etymology | According to the Inca mythology, Pachacámac or Pacha Kamaq (“creator of the land”; being pacha: “land” and kamaq: “creator” or “created” in Quechua language) was a god. The Pachacámac, son of the sun, came to our world and climbed to the highest summit (perhaps a volcano) to throw four stones to the four cardinal points, thereby taking possession of everything that covered his sight and reached his stones. The name also refers to fossorial lifestyle in high elevations. |
