You did not find it weird that Beowulf identified as a geat?

Never read it, but also, wasn't it written like hundreds of years after? I thought the oldest written stories we had were Snorres and the Icelandic sagas.

So the 5th and 6th centuries are still very much guesswork when it comes to scandinavian history.

I just always assumed that the legend of Rome was powerful enough for swedes to claim the Goths. But it makes sense that it's based on fact.
