Ancient Greek mathematicians were erroneously credited with African discoveries

Evidence

Western falsification of history is also evident in the attribution of ancient Africans’ mathematical knowledge to Thales and Euclid. In fact, ancient Africans in Egyptian Sais were able to calculate the height of a pyramid as well as the distance of a ship in the ocean from a given point on land. — Frans Dokman, Beyond Bantu Philosophy_…, 945

  • QUESTION: What is the evidence that Thales’ theorems came from Egypt, and is that a settled historiographic position or a contested Afrocentric claim?
