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.

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.
