The Incas, dyed cords with different colors, tied knots in them, just for to send messages out to the people and the world. It was not easy for people in nowadays to understand the meanings of those cords, however difficulties will always overcome and eventually we are going to be able to communicate with the Incas (through their work of Quipu) and the Egyptians (through their work of papyrus), and then understand their messages.
