Two brothers were cutting peat in a Danish bog in 1950. They found a body so well preserved, they called the police. Closed eyes, stubble, a calm face. They were sure it was a recent crime. It was actually Tollund Man, dead for 2,400 years. A braided leather noose was still around his neck. Archaeologists believe he was a ritual sacrifice, not foul play. His last meal, a barley porridge, was still in his stomach.
