A quipo was a cord about 60 cm in length, tightly spun from variously coloured threads, and to which a number of smaller threads were attached in the form of a fringe. They were used among the ancient Peruvians and Mexicans for recording events. The fringe-like threads were of different colours signifying different objects or events.
