The ishango bone is one of the earliest counting sticks found on earth. The use of that 25,000-year-old, 10 cm long piece of bone with equal distant markings on it is disputed. But whatever the reasoning behind using it, counting sticks, in general, wasn’t invented to be pretty. They were invented to count, and then to use that count to make decisions and take an action. Be that the good old split counting stick which is used to count debt levels in medieval Europe, or possibly the ishanbo bone.
