The Bauche map was published in 1737 by Phillipe Bauche, a French geographer. The map shows Antarctica, well before the continent was “discovered”.
It was reportedly copied from earlier maps and shows Antarctica accurately as it lies with no ice. It shows the Canary Islands in their correct positions and also the correct outline of the underwater plateau on which they are located. (Which means the ancient source map was based upon information of the shape before the glaciers melted and the oceans rose.)
More amazingly, it even shows a waterway which divides Antarctica into two land-masses. Amazingly, in 1958, when the first seismic survey was done, that waterway was discovered under the existing mile of ice. Some geologists believe the last time this ice-free condition existed was millions of years ago.
