I thought even as far back as the 6th century people knew the world is round (Greeks/Romans), they even got the circumference pretty closely calculated. That wasn’t what was in question, it was what they would find that was in dispute. Columbus assumed he was taking a shortcut to get to India because he had some weird notions about the size of the earth (he thought it was smaller). The flat-earther stuff is more a modern conspiracy theory and Columbus’ story was embellished by Washington Irving (of Sleepy Hollow fame) to make it seem like everyone else thought the earth was flat.
Absolutely right. Nobody really wanted to sponsor Columbus because they already knew how big the globe was, and that Columbus’ proposed expedition would run out of supplies before he got to east Asia by going west - because they were unaware of the Americas existing.
The earliest globe that still exists was started in 1490, and finished in 1492, the very year that Columbus set sail. Columbus didn’t return to Spain until March 15, 1493.
Exactly, the average educated estimate of that time was that Eurasia spanned 180º of longitude (which ended being surprisingly closer to the right value) and Columbus thought Asia was much bigger.

as far back as the 6th century
At least 800 years before that, maybe more. Eratosthenes calculated Earth’s circumference around 240 BC. I would assume you have to believe the Earth is round is if you’re measuring a circumference.
You’re right, many (most?) ancient civilizations knew the earth is round.
It’s not a big mental leap. Things disappear over the horizon. The sun and moon are round. Maybe the earth is round too 🤔
I always wondered where the crazy idea that people once believed that the Earth was flat came from.
So, looks like it comes from a single prolific academic that mixed fiction and history, describing people just about a century before him, and that everybody took for gospel. A famous book said “hey, everybody on your grandpa generation believed this”, and it became common knowledge!
I’m not sure I’m even surprised by something like this.
Yes, Eratosthenes estimated the circumference of the Earth “with an error on the real value between −2.4% and +0.8%”, probably sometime between 250-200 BC (his adult life - I don’t think we know the exact date when he published his work).
People knew the world was round long before anyone attempted to prove it by sailing around it instead of just illustrating it with math. Knowing isn’t the same as proving it in the real world. Also, the knowledge the world is round doesn’t establish that there’s a continuous body of water encircling the entire globe. We had to get out there and see what was beyond the known.
I can’t even imagine how exciting that must have been, to see parts of the world that no human had ever seen before. I was just thinking last night that I miss not knowing things about the world. We have all the information about the entire earth at our fingertips now. When I was a kid there was still a lot of mystery left, but the information age destroyed that.
Actually, Columbus was 100% certain the earth was round. What he believed is that the earth was significantly smaller than the mathematicians said, and that he’d be able to sail straight to India from Portugal. He was greedy and wanted to establish new trade routes. Most of the governments of Europe said "No, you fucking idiot, the earth is as big as the mathematicians say it is, and you’re going to starve to death on your way to India. They would have been right had he not bumped into America by accident. Anyway, that’s why native Americans are Indians and why there’s such a thing as the west indes.
Also Columbus was convinced until his death he found India
I’m honestly surprised to still be seeing this flat earth nonsense. I figured it would’ve fizzled out by now.
In 99% of cases it’s not literally believed, but argued for the sport of debate
There’s something interesting about trying to come up with fake science to support the bullshit, and that’s all it’s ever been except for fringe cases
The problem with the existence of the Internet is nothing can fizzle out now. Used to be your village idiot who thought the world was flat and the Bible was literal would be isolated by stigma within the limited society where they existed, and isolated by distance from any other village idiots.
Now you can find a community of idiots immediately. It’s just a web search away. The community reinforces itself, meaning no bad idea ever has to die as long as someone on earth still thinks it’s true.
Calm down, joke police. It’s just a misdemeanor. Let OP off with a warning.
