Previously Hidden Text on a 500-Year-Old Map Reveals New Clues About the Cartographer's Sources and Its Influences on Important Maps That Came Later (nationalgeographic.com) 78

Greg Miller, writing for National Geographic: This 1491 map is the best surviving map of the world as Christopher Columbus knew it as he made his first voyage across the Atlantic. In fact, Columbus likely used a copy of it in planning his journey. The map, created by the German cartographer Henricus Martellus, was originally covered with dozens of legends and bits of descriptive text, all in Latin. Most of it has faded over the centuries. But now researchers have used modern technology to uncover much of this previously illegible text. In the process, they've discovered new clues about the sources Martellus used to make his map and confirmed the huge influence it had on later maps, including a famous 1507 map by Martin Waldseemuller that was the first to use the name "America."

  • What's that body of land in the top right corner of the map? Is it Alaska?
    • No, it's Japan. Yes, too far off the coast for the scale. That point on the east side of Asia is supposed to be Korea.
  • I suspect there was a lot of wilful forgetfulness as to the many sources of knowledge when it came to "western" discoveries and inventions.

    • it's that progress was slowed so much that it's almost like it did.
    • 1. Lots of knowledge was lost as civilizations were overrun by barbarians, libraries were burned etc.

      2. Knowledge was also lost because it was difficult and costly to spread it around before the invention of the printing press. If only one copy of a map exists, a single fire leads to point 1 above.

      3. On occasion, knowledge was seen as a competitive advantage and hoarded instead of shared. I suspect this goes for a bunch of Chinese inventions/discoveries that were subsequently rediscovered by the Europeans.

        The oldest commonly acknowledged surviving written record of Vinland appears in Descriptio insularum Aquilonis, by Adam of Bremen, a German (Saxon) geographer and historian, written in about 1075. To write it he visited the Danish king Svend Estridsen, who had knowledge of the northern lands and told him of the "islands" discovered by Norse sailors far out in the Atlantic, of which Vinland was the most remote. The exact phrasing of this, the first mention of Vinland in known written sources, is as follows:

        ....

        More geographically correct were Icelandic texts from about the same time, which presented a clear picture of the northern countries as experienced by Norse explorers: north of Iceland a vast, barren plain (which we now know to be the Polar ice-cap) extended from Biarmeland (northern Russia) east of the White Sea, to Greenland, then further west and south were, in succession, Helluland, Markland and Vinland. The Icelanders had no knowledge of how far south Vinland extended, and they speculated that it might reach as far as Africa.

          So they, too, left it to some German to write up the results of their explorations. And neither the Vikings nor the Germans made much use of that knowledge, but left it to the Spanish to exploit the riches of that remote land.

          • "The Germans" did not exist at that time.
            It was an area with perhaps 100 small and larger principals, small kingdoms and earlships.
            Despite the success with the Kogge, a trading ship, they were not great sailors anyway.

            The fact that "one german" wrote about it, does not mean many german (rulers?) knew about it.
            Heck, it was not even common knowledge 50 years ago in the western world ...

              Lots of medieval things got lost and were found again, which doesn't mean it wasn't known of, just maybe not considered worthwhile to bother with compared to Rus, India, China. Even Great Britain in the 18th century saw India as more valuable.

          • Some people speculate that the Viking colonies in the New World failed because the climate cooled too much. I've also read that hostile natives eventually drove them out. In either case, it wasn't for lack of trying that the Viking entry into the New World was a dead end.

      Boo hoo.

      When I visit touristy spots (famous temples) in Japan and school is in session, there are often school kids there with an assignment to ask a white foreigner questions in English. This has happened to me 3 times. When they ask me where I'm from and I reply "United States", I get a puzzled look. Then I say "America" and they understand.

        For some reason, people who don't live in Mexico or Canada seem to think Mexicans and Canadians get upset when people living in the USA get called "Americans."

          Well if Mexicans and Canadians don't get upset then that settles it right? No others left in the Americas. Good thing they approved you to speak for them so that this could get cleared up so quickly.

          Possibly true. However, it doesn't hurt to keep them in mind and there are some people who do care. Columbians mostly in my experience and they appreciate the effort when I catch and correct myself before they can do so./p.

        • During a trip earlier this year to Toronto, I had visited Fort York. At least one sign referenced "Americans" plundering and burning the place. Since I doubt they would being doing it to themselves, it stands to reason they were referencing the US soldiers (history class, years ago, touched upon it as an US offensive towards the British which, while successful, wasn't quite as strategic as hoped, the museum at the site of the fort suggests the same but in less sugarcoated language, for fairly plain reasons)

        If you will forgive my bluntness, the problem seems to be your ignorance. The phrase nuestra América crops up frequently in official Cuban media, for example.

        You may try a little harder to avoid exposing your ignorance. It is, in fact, well known that the bulk of both continents fully recognize the hubris of the US in identifying only themselves as "Americans" when "America" refers to the continent(s).

          The USA is the *only* country in the Americas with 'America' as actually part of it's official name, so over a century ago those of us in the US became known as "Americans" as a form of shorthand, since "United Statesian" or whatever is just ridiculously cu

          No one spoke up as to be upset that we're known as Americans.

          Right, wrong, or indifferent... it's what we are called. United Statesians or United States of Americans just doesn't quite roll of the tongue.

      not to a nation that was going to be formed some 270 years later.

      And then a bunch of states got together, i.e., united, and called themselves the United States of America .

      A bunch of other states of America that preferred not to be united later developed a massive inferiority complex when the rest of the world shorthanded the name and nationality to "America" and "Americans." But they daren't call themselves, e.g., "The Bazilian State of America" and "Americans," because "ewwwwwwww!"

      Super short version: Once you've ceded the name, most people don't want to hear you complain.

      • That may be because those other countries don't speak in English. "América" refers to the whole north-south continent in Spanish [wikipedia.org] and Portuguese [wikipedia.org]. The rest of the world didn't "cede the name", they simply weren't using it in your language, but theirs.

              Just like people in Europe call ourselves Europeans. Maybe it's you who don't know Spanish or Portuguese?

              The European who is confusing language with nationality is supposing that I don't know a language, in addition the fact that it somehow proves his argument.

              Try again.

    • Of course! Now today we refer to that continent as "the Americas" while our nation is known for short as "America" as in "the United States of". Just like Mexico is known as Mexico because it is the short version of "The United States of Mexico." But you knew that already and just came here to hate.
