I'm really curious what this means in the larger context: does it refute the fundamental evidence that Norsemen reached the New World before Colombus, or is there enough other evidence that this is no big deal?
Archeological evidence found in the 1960s proves quite clearly that Norsemen reached the Americas 500 years before Columbus. In fact this evidence turned up - and got quite a lot of attention - in the 1960s, which is when this map was first published. But by the 1970s, analysis of the ink made it fairly clear it was a forgery.
This news is just that a more detailed analysis has been done, proving the map long believed to be a forgery was definitely a forgery. But the map was never really considered evidence of anything in particular; it was always questionable.
It doesn't have any significant impact. The map was already assumed to be fake by most scholars. We have both historical and archeological evidence for the Norsemen reaching the new world, so that is not in doubt.
None, really. People will still pay extraordinary amounts of money for old documents with shaky provenance on the basis that they'll have it and you can't, only to find out they've been duped. T'was ever and t'will ever be thus.
An NFT is just a number on a ledger. The fact it represents ownership of anything is an agreement, and there’s nothing about the NFT itself that enforces that agreement. What are you going to do about it if someone, maybe the artist or their estate decides to disagree?
