There is indeed the Myth of the flat Earth that is a misconception about the beliefs of scholars in the Middle Ages and some scholars certainly understood the concept of a spherical Earth since at least Eratosthenes. I’m referring to earlier history like ancient Egyptian, Chinese, and pre-Socratic Greek cosmologies. Admittedly, it’s not a great example since most of the debates about it are lost to history, and such debates wouldn’t involve the same kind of reasoning and evidential standards we use today.
