The Cord Keepers - Frank L. Salomon - Bog

The Inkan empire did not have writing as it is usually understood. The Inkas kept track of information - including their social and political organization - on khipus, knotted cords of cotton or wool. This book offers a reading of the khipus of one Andean village, where villagers have conserved a set of these enigmatic cords to the present day.
