Eratosthenes made a good guess
Another false statement.
Eratosthenes was not guessing. If you had any knowledge of the subject you would know that. if you had any interest in the truth, you would have checked.
Eratosthenes deduced a method for calculating the size of the Earth. It was not a guess. It was a logical deduction stemming from observations and a knowledge of maths. The method involved a repeated experiment and maths. It was not in any way, shape or form a guess.
The inaccuracy is due to the limitations of technology and resources available to him, particularly that he could not very accurately measure the distance between two cities. But the method is correct and his results are not a guess.

CrakrJak, you're making things up again.
here`s what you wrote:
Also, people didn`t "know" the earth was round. It was an unproven hypothesis.
Just a few posts later, you`re claiming that you wrote something completely different:
[quote]Therefore there were several theories as to how large the earth might be.[/quote]
As usual, you are not consistent with either yourself or reality. You change your position on an ad hoc basis in response to proof that you are wrong.
I have no doubt that next time the subject arises you will revert to claiming that people didn`t know that the Earth is round. If someone proves you wrong again, in that future thread, you`ll probably do the same thing you`ve done here - shift the goalposts and make untrue statements about what you wrote.
You`re canny enough to know that it`s easier to make a false statement than to prove it wrong, so you`re right to just keep on as you
