The Nazca culture (also Nasca) is thought by many archaeologists to have been the civilization which flourished from approximately 100 BC to about 600 AD in the river valleys of the Rio Grande de Nazca drainage and the Ica Valley. Having been heavily influenced by the preceding Paracas culture, which was known for extremely complex textiles, the Nazca produced an array of beautiful crafts and technologies such as ceramics, textiles, and perhaps the famous geoglyphs which bear their name.
