Marita Genesis of Potsdam, Germany has an interesting area of study: execution site archaeology. Genesis is just one of a number of scientists and scholars interested in finding out how those executed died and how executioners, particularly in the Middle Ages, lived. Matthias Schulz of Der Spiegel has the story.
Archaeologists at various sites are studying the remains of "thieves, sodomites and child murderers" to learn how they were executed and what was done with the bodies afterwards. They are also looking at torture and witch-burning, and the grim qualifications for the hangman.
