Pachamama is a goddess revered by the indigenous people of the Andes. She is also known as the earth/time mother. In Inca mythology Mama Pacha or Pachamama is a fertility goddess who presides over planting and harvesting. She causes earthquakes and is typically in the form of a dragon. She is also an ever present and independent deity who has her own self-sufficient and creative power to sustain life on this earth. Pachamama is the wife of Pachakamac and her sons are Inti the sun god, and Killa, the moon goddess. In Quechua cosmology, these are the four organizing principles of nature based on water, earth, sun, and moon. Llamas as well as burned, elaborate miniature garments are sacrificed to her. After the conquest by Spain, which forced conversion to Roman Catholicism, the figure of the Virgin Mary became united with that of the Pachamama for many of the indigenous people. In pre-Hispanic literature, Pachamama is seen as a cruel goddess eager to collect her sacrifices. As Peru began to form into a nation, however, Pachamama began to be–and to this day is–perceived as being benevolent and giving. She is also seen as nature itself. Thus, problems arise when people take too much from nature because they are taking too much from Pachamama.
