Does the Ishango Bone Indicate Knowledge of the Base 12? An Interpretation of a Prehistoric Discovery, the First Mathematical Tool of Humankind [article]

Vladimir Pletser
2012 arXiv   pre-print
Additional circumstantial evidences are given to support the hypothesis that the Ishango bone is a primitive mathematical tool using the base 12 and sub-bases 3 and 4.  ...  The Heinzelin's Ishango bone has notches that seem to form patterns, making it the first tool on which some logic reasoning seems to have been done.  ...  Appeal to the Reader Like the mathematical knowledge was maybe transferred from Central Africa to Ancient Egypt and then to Europe, the bone followed a somewhat similar odyssey.  ...
