No one is denying that people have believed in a globe earth.
Ladislaus is denying that Popes Nicholas V and Alexander VI were talking about a globe earth:
No, but you've certainly shown yourself to be a posterior orifice.
There is in fact a southern magnetic pole on a Flat Earth model beyond Antarctica. Nevertheless, are you suggesting that the Pope was teaching Magisterially that there's an "Antarctic southern pole"? Maybe that statement meets the notes of infallibility too.
Stop for a second and think about what ANTarctic region means, eh? It's simply the area opposite to and away from the Arctic circle. There's an Arctic and an ANTarctic on a flat earth too. When in the souther hemisphere, thiings rotate the other way due to perspective, which is why it's called ANT.
He's trying to fool readers and suggest they were talking about magnetic poles on a flat earth. Then he's dishonestly presenting a strawman ("teaching Magisterially", "infallibility"). And another strawman: "ANTarctic region" instead of Antarctic pole.
That's why I'm showing some maps to demonstrate, what cartography was after Columbus.

That art proves nothing but the conceptions of the artist about the world.
Indeed. But if you find virtually all globes and globe-projections from a certain time, you can infer that there is a reason why that is like it is.
