Mario Renner and Henry Westphal are metal detecting in Ziegelroda Forest, near the German town of Nebra. They’re up to no good. In fact, since they’re unlicensed the two are no better than looters. Yet they come across an incredible hoard of weapons and artifacts buried some 3,600 years ago. Of the items they dig up, one will eventually be recognized as hugely significant in our understanding of Europe’s Bronze Age.
