AT FIRST, THE skeleton in grave 134 seemed unremarkable. In 2018, archaeologists in Germany descended upon the ancient town of Nida, about a mile and a half outside Frankfurt. The archaeologists focused their attention on excavating a cemetery. Here they would look at more than 100 plots where people had been buried, often with objects. So when the archaeologists came upon grave 134 and saw what appeared to be a necklace resting below the skeleton’s chin, they weren’t shocked or overly curious.
