It’s actually a myth that people still thought the Earth was flat back then. A myth that still gets published in school books unfortunately.
The ancients Greeks figured out the Earth was round.
The reason Columbus had trouble finding a sponsor for his voyage is that nobody wanted to pay for it.
Not that idiots who gripe about people that died of the flu 500 years ago care about facts.
“It’s actually a myth that people still thought the Earth was flat back then. A myth that still gets published in school books unfortunately.”
Absolutely.
People had known that the Earth is round since the time that they first were able to sail far enough from the shore to watch the shore disappear over the horizon. It wasn’t lost on them why you would see the high ground reappear first.
