For example the Piri Reis map, where they followed the ice around the entire ocean that were in. From 1513, created by the ottomans who had a global empire.

Can you point to the version of this map that shows that, because the only one I can find shows the East coast of the Americas on the left edge and the west coast of Europe/Africa on the right and the southernmost point appears to still be in South America ("these shores are said to be very hot").

Or the map found in a copper cylinder, over 1,000 years old, shows all of our continents and a dozen or so further past the ice. Outside of our ocean. They even have names.

The one that only exists as a low quality photo in a single article from 1907? The same article that questions it's claims of being that old? The map that has several circles drawn on it and only one or two that flat-earthers interpret as a wall and aren't drawn like the other continents, but more like latitude lines? The one that doesn't actually have any names on it?

There are dozen of examples.

Would LOVE to see them.
