Explanation:

The Inca civilization employed the quipu, a device composed of knotted and colored strings, for record keeping and communication. Used as an alternative to a writing system, the quipu enabled the Inca to record a variety of quantitative information, such as census and tax data, land allocations, movements of armies, and astronomical observations.

Notably, differing knots and string colors generated many thousands of combinations, allowing them to hold qualitative information such as ideas and potentially even poems.

Figure 8.36 presents an example of an Inca quipu, demonstrating its complexity and portability. As described by Pedro de Cieza de Léon, a 16th-century explorer, the utility and accuracy of the quipu in chronicling various elements, from precious metals to livestock, astounded even the Spanish.
