In 2021, at Suontaka Vesitorninmäki, Hattula, in Finland, archaeologists discovered the grave of a Viking warrior, the body wearing female clothes, on a soft feather blanket with trinkets, and two swords. They believe that the person had Klinefelter syndrome, giving rise to XXY chromosomes. This had probably been a person respected in their eleventh-century society, wearing women's clothing, fighting as a warrior, perhaps understood to be one of the many sexes on the huge spectrum of sexual identity that was then known but which we have tried to forget.
