Abstract

Because these archaeological artefacts have been interpreted numerically, they are of interest in the history of mathematics. If, as alleged, the numbers record stellar and planetary movements, they are of interest in the history of astronomy. This article shows that the code of the quipu is richer than previously believed, and the astronomical hypothesis is re-examined in this light. © 1969 Nature Publishing Group.
