Basically Antarctica is a very long way away from the old world (you have to sail south from South Africa for roughly 2,500 miles before you get to Antarctica). Because earlier voyages of discovery were intended to open routes to known destinations (ie Columbus trying to get to Asia by sailing West) and were quite dangerous, nobody may have been willing to finance or undertake a voyage to the south just to see if anything was there, at least not for a few hundred years after Columbus.
Also of course it's really cold down there; a fact that probably encouraged a lot of explorers to try mapping more pleasant places first.
Antarctic was discovered in 1773........... Or was it? Scientists are investigating some so called pyramids, they are doing analyisis to see whether they're man made or natural. There was also a map, the Piri Reis map, which depicted Antarctica exactly how it is, but without ice! This was 300 years before it was "discovered"..
Have you ever been there? If not for the internet and school... Would you know it existed?
Now... Go back in time BEFORE the internet and email, tv and phones... Who would ever think to head to the cold...cold...cold... southern pole?
It just took longer for information and technologies to advance to A.) research that region and B.) to spread the news.
Probably for the two reasons of its down on the map further away and itscreally cold
still it is far away from population. It is situated in polar region and the possibilities losing directions made it hard to reach there.
