Ilustração de Conquista de Peru-um carteiro Inca mensageiro

Vintage engraving showing a scene from the Conquest of Peru. An Inca Postman or Messenger carrying a Quipu. Quipus, sometimes known as khipus or talking knots, were recording devices historically used in the region of Andean South America. A quipu usually consisted of colored, spun, and plied thread or strings made from cotton or camelid fiber. For the Inca, the system aided in collecting data and keeping records.
