The only identifiable form of "writing" known from the Inca civilization is their knotted quipu. These colorful cords, knotted in various ways, were used to convey information such as census data, tributes, and even historical accounts, serving as a complex accounting and communication tool in the absence of a formal writing system. Additionally, the Inca's extensive network of roads, known as the Inca Trail, spanned over 25,000 miles across diverse terrains. This engineering marvel facilitated trade, military movements, and the swift relay of messages throughout the empire, showcasing their advanced organizational skills and commitment to connectivity in a vast empire.
