Prehistoric notation systems in Peru, with Chinese parallels
This morning, by chance, I learned about the great urban center of Caral in Peru, 120 miles north of Lima. It was occupied between ca. 26th century BC and 20th century BC and had more than 3,000 inhabitants. It was said to be the oldest urban center in the Americas and the largest for the 3rd millennium BC. Caral had many impressive architectural structures, including temples, an amphitheater, and pyramids that predate the Egyptian pyramids by approximately a century.
What attracted my attention the most, however, is this:
Among the artifacts found at Caral is a knotted textile piece that the excavators have labelled a quipu. They write that the artifact is evidence that the quipu record keeping system, a method involving knots tied in textiles that was brought to its highest development by the Inca Empire, was older than any archaeologist previously had determined. Evidence has emerged that the quipu also may have recorded logographic information in the same way writing does. Gary Urton has suggested that the quipus used a binary system that could record phonological or logographic data.
