    Frequently Asked Questions

    The Lebombo Bone is a prehistoric baboon fibula discovered in the Lebombo Mountains, dating back to approximately 35000 BCE. It is widely recognized as the world's oldest known mathematical artifact, featuring 29 distinct notches that suggest it was used as a tally stick. This discovery provides crucial evidence for the early development of mathematical thinking and record-keeping in ancient human history.

    As a primary example of prehistoric mathematics, the Lebombo Bone indicates that early humans were practicing numerical notation and counting long before the rise of major civilizations. It predates other famous artifacts like the Ishango Bone, placing the origins of mathematical logic deep within African archaeology. This artifact suggests that early humans used tally sticks to track lunar cycles or other recurring events.

    The Lebombo Bone was unearthed in Border Cave, located in the Lebombo Mountains between South Africa and Eswatini. Scientific dating places the artifact at roughly 35000 BCE, making it a cornerstone of African archaeology. Its age and clear intentional markings offer a unique window into the cognitive abilities and daily lives of humans living during the Late Stone Age.
