Captain Cook was thought to have been the first navigator to round Cape Horn (the southern tip of South America), from the Atlantic into the Pacific, and according to maps at his disposal at that time (in the mid 1700’s), a large continent should have been seen just to the south of the tip of South America, a huge continent, shown on the world atlas maps of Gerhard Mercator (drawn about 200 years before Cook’s time), whose outline is remarkably like the actual outline of Antarctica, but is shown to be about 4 times too big, thus almost touching the southern tip of South America on those medieval maps, composed hundreds of years before the Russians “discovered” Antarctica in 1818.
Cook was no doubt expecting to see the big continent just to the south of Cape Horn, but these maps showing Antarctica were compilations of pieces of ancient maps, patchworks of bronze age source maps, and so, the latitudes of the shorelines of Antarctica were obviously misread for the compilations, although the accurate details of the shape and location the continent indicate that ancient navigators were there, measuring time, to thereby be enabled to measure east-west distances, to accurately measure and map the earth, by the stars, as detailed in the explanation under Ice Age Civilizations (article #2).
The 1532 Oronteus Finaeus Map shows the coastal mountain ranges of Antarctica, which are now under thousands of feet of snow and ice, and the Buache Map of 1739 even shows the two land masses of Antartica which are now under all the snow and ice, so the ancient navigators were there, even early in the Ice Age, lending credence to the Genesis account, that this was going on circa 2200 B.C., just after the Deluge, around the time of the Tower of Babel incident, when the Middle East was wet and lush, because of the dense cloudcover which at that time was being caused by the warmer ocean waters of the Ice Age. (It’s the only way you can explain the engine for the prolific evaporation for the dense cloud-cover necessitated for that kind of massive snowfall.)
