"Wasn't Mercator's popularity due to it making all the key trading ports more easily visible?"
No, not at all. Rather, the #Mercator map was just the simplest mathematical #mapprojection that allowed any sailor to use the easiest form of #navigation possible, in pre-modern times.
Most folks weren't shown how this map was supposed to be used, so it often gets misinterpreted by moderns

Nice idea of #Map Cutouts found in used book store. But sadly in well meaning, but wonky #Gall-Peters #mapprojection
