LIMA, PERU—Twenty-five well-preserved quipus, made of multiple knotted wool and cotton strings of different colors, were discovered at the archaeological complex of Incahuasi in Peru’s Lunahuana Valley. Quipus, which are thought to have been used for record keeping, are usually found in a funerary context, but this collection was unearthed in warehouses, or kallancas. This is “what makes us believe they were used for administrative purposes,” archaeologist Alejandro Chu, who is in charge of the site, told Peru This Week.
