Several sites of prehistoric rock art exist in Chile. The works comprise the three main techniques employed by the pre-Hispanic artists: petroglyphs (engravings), pictographs (paintings) and geoglyphs (markings or designs on the land). The ones pictures on this postcard are the pictographs of Milla: “On one of the panels, two camelids with blank faces, one with an empty womb, are depicted walking, followed by a person wearing a feather plume and preceded by another dressed in a tunic decorated with a zigzag motif and headdress similar to the traditional conical hats of the Tamarugal Pampa.”
