Actually, while I am on your side, Delmar, that isn't entirely true. Non-Judeo-Christian people have known the world is round since before Christ. Ancient Greek mathematicians figured it out, using astronomy and geometry, and were surprisingly close to the accurate diameter of the earth. Now, granted, only some people knew this, and your average uneducated masses didn't. But learned men did know.Delmar said:We know that in the time before Columbus the " scientific consensus" was that the world was flat!
Please provide evidence that the writers of the Bible believed the earth was flat. While you are at it provide evidence that our solar system is not the center of the universe.
It's also true that this knowledge became less known through the Dark Ages, but even in the years leading up to Columbus' voyage, the debate was NOT whether the earth was round. The debate was how big the earth was. There were two camps, each side favoring a different area of science.
One camp (including Columbus) said the Earth was smaller than the Greeks said, because they observed meteorological phenomena and the movement of oceanic waters. Being a mariner, Columbus naturally favored this area of science. And that data indicated there was a continental land-mass only about 3,000 miles to the west, give or take, based on weather patterns and ocean currents. And everyone figured that had to be east Asia. Columbus wanted a trade route to Asia that wouldn't have to go around the southern tip of Africa.
The other camp used astronomy and geometry, and rightly knew the approximate size of the earth. And if that was the case (which it is), then Asia would be two or three times as far to the west as Columbus was claiming. Such a western trade route to Asia would have been utterly impossible.
Amusingly, both camps were partly right, of course. What neither of them counted on was a large, undiscovered continent to the west, between Europe and Asia.
Just want to put this forth to clarify the issue, and to dispel the myth that people have always thought the earth was flat before Columbus.
Now, all of that said, ancient peoples prior to the Greeks DID believe the Earth was flat. Except, of course, for the Hebrew people, who knew from their divinely-inspired scripture that the earth is, in fact, round. They had the advantage of many scientific understandings that no one else on Earth had at that time. Washing hands in running water rather than still water, the dangers of eating pork and shellfish, and many other things. The first book of the Tanakh ever written contains scientific information possessed by no one else on earth at the time, such as the fact that the earth hung in space, rather than sitting on the back of a tortoise or some such nonsense.
