I wish I was there to remember it lol.
On a different note, historians will know exactly what happened; the story is written around the stone in runes...
Those are not really runes, they include Cyrillic characters in runic style. I see the words "v sedemiy den maya" (on the 7th day of May) and "kopim" (with a spear).
i also don't think runestones have artwork like this on them? like fuckin have fun carving that with a chisel.. and the paint would last approximately 2 hours painted onto a rock in nordic weather.
Certainly i've never seen a runestone with artwork on it and i live in sweden, hell they don't even have that much text, it's like the ancient equivalent of graffiti tags.
TORBJÖRN MADE THIS STONE IN HONOUR OF HIS DAUGHTER HILDA WHO MADE A REALLY LOVELY STEW
It's not weirder than many other things that are from centuries or millennia ago. It's always fun to see the weird theories people come up with, everything from aliens to masturbatory use.
