I’m playing AC Valhalla and just noticed at least one of the pigs in my village is all inked up, I know these games strive for historical accuracy with some stuff but couldn’t find anything about it online
This post is about Norse tattooing traditions, or the lack thereof. u/Platypuskeeper's answer goes into detail about the current scholarship on the topic. You can read through that while you wait for an answer but I would guess that Scandinavians tattooing their pigs but not anything else would be highly unlikely.
