There is speculation as to why maps are drawn this way, it supposedly benefited the British, Scandinavian and Russian Empire (most of whom made the maps in the 18th & 19th centuries! - as well as french, Germans, Italians and other, but they benefit from the "north looking larger than southern hemisphere countries too.
It became the standard map projection for navigation because of its unique property of representing any course of constant bearing as a straight segment. Such a course, known as a rhumb or, mathematically, a loxodrome, is preferred by navigators because the ship can sail in a constant compass direction to reach its destination, eliminating difficult and error-prone course corrections.

I have never heard of those Vatican and Islamic tales of Greenland.
Current estimates are that the Greenland ice sheet is at least 400.000 years old, that's at least half a million and probably more like 800.000 years old, that still however means that within the last million years much of Greenland may have been free of ice.
It also means' that unless humanity has a very long memory these ancient records and folk memory's may have been talking about another location and NOT Greenland at all.
What happens when island's rise from the sea bed, ocean current's change direction around them and when they sink back down those same current's then change again, if it was not for the Oceanic conveyor current's we in northern Europe would be far colder than we are today especially in western Europe, how much of a change of direction in the gulf stream would have to occur for Greenland to be the beneficiary of that warming affect instead?, still the estimates are 400 to 800 thousand years BUT it was not always ice bound.
Interesting thread, that snippet alone that there are tales of the land being warm is interesting though you know we do know a lot about the Viking settlement prior to the little ice age, it was a warm period in recent geological history and during that time there were claim's that the southern part of Greenland had some forest and the Viking's settled there using there colony to explore further west until they found Vinland - the land of vines and forests much like there home but at that time even warmer which we now know was the newfoundland colony which was probably either wiped out by the local peoples (Skraelings in Viking tongue meaning foreigners) or went native - probably wiped out or the natives would have been using swords, then came the little ice age, the Viking settlement on Greenland died a slow death over several generations and the glaciers even rolled over there church leaving only the foundation of it's wall's and those of a few houses that have been excavated, over the course of those generations the settlers at the Greenland colony went from being about 6' on average very tall for peoples of that period to about 5'2" and the bones and teeth of those final generation's show that they died more of malnutrition and starvation than from the cold itself, at that same time the canals of Venice froze solid and it was not until about 1814 the Thames in London used to freeze every winter solid and they would hold an annual fair and market on top of the ice itself.
The Norse despite having great ship's whose ship lap planking (overlapping planking creating ridges along which air could be trapped making them quicker in the water as the air reduced the friction of the water against the hull) made them a semi planning (Ride over - the fast they move the higher in the water they are and they displace less water as a result) hull despite there displacement (ride through - having to displace an equal amount of water) shape were far from the most cultured people to have ever called Scandinavia there home, there ancestors perhaps 4000 years ago during another mild spell in Denmark built buildings that we would recognize today, square built proper building's with porches, room's inside etc but by the time of the Viking's other than there great long hall most of there homes were hovel's and some Vikings even lived in holes dug out of the side of hill's using the smoke of there fires to keep pests and creepy crawlies at bay (they even used the ruins of roman villas as stables and lived in such hovels themselves).
Columbus supposedly gave an account of seeing sea going native American ships which sailed between Hispaniola (Haiti) the other islands of the Caribbean and the mainland and it is possible if we look at the coc aine mummy's and tobacco as well as other south American compounds not found on this side of the Atlantic that this could mean that it was THEY whom discovered us first and not the other way around, then we have the Brazilian cover up of the discovery of a roman merchant ship in the bay of rio de Janeiro, after the American discoverer went public and asked for a permit to explore the wreck upon which he had seen several amphora of the type found in the roman empire the Brazilian navy then dumped sand and gravel over the ship since if there nations founder can be proven to have NOT discovered there country it could be a shock to there patriotism - as well as meaning the native people are probably also not the ignorant savages they are made out to be there.
So what I am saying is that the Viking's knew of Newfoundland and back then Vines grew wild there as the climate was very mild at the time of there (re)discovery of the Americas, Greenland has probably been almost entirely frozen (Except for coastal southern areas) for the better part of a million years (and we are 'supposedly' less than 300.000 years old as modern humans) so unless someone was around back then and our oral history goes back that long (the Indians - India - have an oral tradition that talk's of millions of years ago and even of things such as a bridge build between India and Sri Lanka 400.000 years ago en.wikipedia.org... and arrows of the god's that explode in what sound's awfully like a nuclear explosion/war) BUT like I say the Boffin's working with the best 'fragments' of (ACCEPTED) Evidence that they can and with the idea's of a Victorian gentleman whom visited some pacific islands (to guide them) are convinced we are less than 300.000 years old as a species (they believe we are nothing but animals I disagree obviously) - and that human's that existed before that were knuckle dragging moron's whom banged stones together all day long.
Anyway even when faced with evidence like this there are people on this site that IGNORE, DENY and then make all kinds of excuses for but basically refuse to accept even though if real it would fit perfectly into the modern species timeline that they cling too like a child's comfort blanket.
Let's just go for a mental experiment, imagine that the entire south American continent had undergone a huge cataclysm, as the continental plate of south American drifted ever further westward over the older thick ancient pacific plates it may have drifted over the remains of something called a proto-continental mass, an unusually thick pacific ocean plate which itself may once have been a continent much - much earlier in the earth's history, meanwhile as the ice melted at the end of the last ice age the pressure on the thin - young - ocean plates in the Atlantic increased AND simultaneously the magma beneath them lowered in pressure as it moved back under the areas were the ICE (which was over 2 miles thick in places) had formerly depressed the northern continent's causing the still ongoing process we today call Glacial Rebound.
Something may have given, a huge earthquake as the entire continent of south America TILTED cataclysmically thrusting hundreds of miles of former land deep into the Atlantic ocean while simultaneously the probably far older than this crowd accept city of Puma Punku/Tihuanaco/tiwanaku was shattered it's great stones flung about like a child's building block's as it was thrust upward from sea level to the great heights were it now sits on the Bolivian altiplano, once a city on a western south American fjord with a sea port now lost to the clouds.
Meanwhile a huge tidal wave - or several of them - washed over both the Atlantic and the pacific ocean's wiping out the majority of human civilization that had escaped the destruction and natural sea level rise of the end of the ice age leaving only the hunter gatherer tribal's -

I imagine most people don't understand this. I can hear school kids before map study got canned. "It's too hard and boring."
I don't think most people can even use a map.
