Khipus, the portable information archives created by the Inca, may stir up memories of 1970s macrame with their long strands of intricately knotted, earth-toned fibers, but their function more closely resembled that of a densely plotted computerized spreadsheet.
As Cecilia Pardo-Grau, lead curator of the British Museum’s current exhibition Peru: a journey in time explains in the above Curators Corner episode, khipus were used to keep track of everything from inventories and census to historical narratives, using a system that assigned meaning to the type and position of knot, spaces between knots, cord length, fiber color, etc.
Much of the information preserved within khipus has yet to be deciphered by modern scholars, though the Open Khipu Repository — computational anthropologist Jon Clindaniel‘s open-source database — makes it possible to compare the patterns of hundreds of khipus residing in museum and university collections.
Even in the Incan Empire, few were equipped to make sense of a khipu. This task fell to quipucamayocs, high born administrative officials trained since childhood in the creation and interpretation of these organic spreadsheets.
Fleet messengers known as chaskis transported khipus on foot between administrative centers, creating an information superhighway that predates the Internet by some five centuries. Khipus’ sturdy organic cotton or native camelid fibers were well suited to withstanding both the rigors of time and the road.
A 500-year-old composite khipu that found its way to British Museum organics conservator Nicole Rode prior to the exhibition was intact, but severely tangled, with a brittleness that betrayed its age. Below, she describes falling under the khipu’s spell, during the painstaking process of restoring it to a condition whereby researchers could attempt to glean some of its secrets.
