In 1950 the mummified corpse of the Tollund Man who lived during the 4th century BC was found in a bog on the Jutland peninsula of Denmark.
Tollund Man’s body was so well-preserved that it was first thought to be that of a recent murder victim.
Although initially thought to be a hanged criminal, subsequent scholarship suggests that he was a human sacrifice because of the position of his body and closed eyes and mouth.
