Actually the thing was found in 1960...............Patrice L was assassinated in 1961............so they probably looked around..............and like wow.........i am sure that that was the reason.........



The Ishango Bone, a notched talley stick discovered at Ishango in the Congo (Zaire) in 1960 by Jean de Heinzelin de Braucourt, and now preserved in the Royal Belgian Institute of Natural Sciences, is one of the oldest known objects that may contain logical or mathematical carvings. It may be simply a talley stick.
