>>13149735if you type in “map of the earth 1600” into an image search engine, nearly all the maps of the entire “globe” show a concave sphere. the same applies to “ancient maps of the earth” or “ancient maps“.
this shows that nearly all the cartographers in the renaissance (early 1600s) thought the Earth was a concavity, not a convexity. what happened at this time? The “primitive” man idea is ruled out because Concave Earth Theory (CET) is counter-intuitive. previous to early 1600 AD only Plato believed that we lived inside a concave Earth (Phædo). the Earth (e.g. water) looks like a flat plane to the horizon and so an uneducated man would presume that the Earth was flat.
