I'll digress for the sake of others who may also find the flat earth interesting Professor Donalds Simanek' Pages (Lock Haven University of Pennsylvania) are a pretty good collection of brain food. Click on Myths and Mysteries of Science then Flat Earth and read that Aristotle pretty much had the round earth nailed until he got to #6(elephant theory).
Few paragraphs down discusses Erathosthenes 200ish BC measurements of shadows at Alexandria and Syene(now Aswan) where he closely estimates the size of the
earth. Much further down some flat earthers rethink his measurements and conclude the 7.2 degree difference in shadows is because the sun is 3000 miles away.
Tamarack Mines Plumb Lines is a good round earth brain teaser.
Museum of unworkable devices page is a interesting place to spend some time.
