In the 1800s, a Viking burial site was unearthed in Birka, Sweden. The burial included a Viking ship, weaponry, game pieces, horses and riding accessories, and other tools. The grave was documented as that of a Viking warrior, as evidenced by the contents of the burial. As Brown shares in her book, most “sexing” (that is, determination of whether a skeleton is male or female) throughout the history of archaeology has been sexing by metal. That is to say, where weapons are found, it is deemed to be a male, where jewelry is found, female. There are a number of reasons why the field of archaeology has used this approach even as DNA testing has emerged, and Brown provides an interesting overview of this process.
