From The-Best-Man-For-The-Job-Might-Be-A-Woman Department :
Archaeologists had always thought they had found the ideal Viking male warrior’s grave in southeastern Sweden. There were swords, arrowheads, and two sacrificed horses, so the interred must be a man, right?
Then Stockholm University bioarchaeologist Anna Kjellström closely examined the warrior’s pelvic bones and mandible. To her, they seemed feminine.
When none of her colleagues seemed impressed, two types of DNA testing were ordered. The results were clear: “he” was a woman.
Read Viking lore and you will find some female references. A tenth-century Irish text relates the story of Inghen Ruaidh, or Red Girl, a female warrior who supposedly led a Viking fleet to Ireland. But many considered these stories to be mythological embellishments, perhaps to conform to modern expectations.
But now we know there was a lot of truth in those old stories.
