The Egyptians may have known of the rotation and even of the orbit. Forget
which Egyptians calculated the diameter of the earth. They were only off
by about 225 miles, using sticks and shadows at a certain time. Way before
Europe and Rome admitted the earth was not flat.


It was Eratosthenes, a Greek. But he did hang out in Alexandria.
