Bernstorf

Linear B in Bavaria is a forgery, right?

Maybe, but not necessarily. Could have gotten traded somewhere in the Mycenaean sphere of influence and traded on to some savages onto some other savages.

Maybe not.

In 2000 the imposing fortified citadel of Bernstorf near Munich in Bavaria, which burned down in about 1300 B.C. or thereafter, and had already yielded a gold treasure of vaguely Aegean appearance, produced two amber seals that seemingly bear sign-groups in Linear B. Since these finds were so outlandish, they attracted little notice: indeed, the seals’ authenticity has been questioned, unfairly as it appears. However, a new reading of the signs suggests links with the slave-women called Ti-nwa-si-ja or Ti-nwa-ti-ja who appear in the Linear B archives of both Pylos and Knossos.

It is suggested that both the seals and the treasure were the symbols of authority of a defunct Mycenaean town called Tinwanthos, whose women were enslaved when this town was incorporated into the kingdom of Pylos; the Pylian rulers would have sent these valuable objects as diplomatic gifts to trading partners far away, so that nobody could make use of them.

But what if the gold treasure is forged, too?
The finders of both artifact groups were the same two people. They got nearly a million DMarks for it and also a museum and medals.

was it found in the red circle area ?

It wouldn't even be the biggest hoax in historical artifacts, I'm afraid. Not even top 10.

nope, a few hundred kilometers more to the southwest

Still one of the most awkward ones.
According to the German wikipedia, one of the finds was made using a fortune teller of sorts.

I asked because E-V13 is typically but it seems they aren't linked

is typically Greek*

But those should be Slavs from the balkans, who moved to czechia during times of the austro-hungarian empire, right?

(slavs of mediterranian ethnicity)

Yes it is, according to all archaeologists

Though it wouldn't be sos trange considering Cypro Minoan marks and perhaps even Ugaritic marks were discovered as far as the Western Mediterranean

Riding your boat westward on the mediterranian is one thing. Going over the alps is different.
Also, it seems that all scientists agree that the site Brenstorf wasn't settled during that time around -1300, and was actually just some sort of refugium for nearby settlements-

The Western Mediterranean is more easily explained than Bavaria, due to the Globalization present in the Mediterranean at the time

picrelated is the gold claimed to be from the Bernstorf site

>3000 samples
Good but still not definitive
Gene flow from south Europe can explain 5% of E-V13 in Germany. Could also be remnants of Roman rule

Also Y-haplomemes are not really informative of ancestry past 1000 years (typically 1000s of years)

The other inscribed amber is even more ridiculous.

Obviously parts of an ancient Bavarian spaceship.

There were Bronze age trade routes through Central Europe that connected the Mediterranean and Baltic Sea though.

But that's a few hundred km east of, avoiding the alps. Bernstorf however is right north of the alps (you can actually see them from there with your bare eyes)
