This interesting article from Tor.com talks about how some of the bodies found in Viking graves with weapons are actually women. It seems that even though the sagas speak of women fighting alongside the men, many archaeologists would just assume that if there was a weapon in the grave then the person buried there had to be a man. Pretty lame move in my opinion.
Ignore the subhead of the article. The study they reference claims half of the “settlers” were female, not half of the “warriors” found in graves but why expect a journalist to let truth stand in the way of a good headline? (Is my bias against lazy writers who don’t bother to read the entire article they are lifting quotes from showing?)
Anyway, I highly recommend reading the comments, there are some thoughtful additions and a few links to further reading.
