Cairo Map

"The world's oldest map, which Richard J. "Dick" Benson dates to 6018 B.C., depicts the elegant theory of mathematics embodied in the planning of the city of Cairo. The megaliths shown are (C) Cheops, (K) Kephren, (M) Mikerinus, and (S) Sphinx. Benson's work may well provide a helpful, radically new framework for historical linguistics as well as uncover a lost simplicity in the art and numbers of geometry."
