Quipu of the Tahuantinsuyo Empire

Quipus (1200–1532 AD) were the Inca Empire’s record-keeping system, using knotted cords to encode information. Variations in knot type, position, and color represented data for administrative tasks like census and resource management, highlighting the empire’s complex societal organization. This tactile communication method demonstrates the Inca’s ingenuity in managing vast territories.
