The museum is not a pony farm. Because art reveals a wealth of criminal acts in its pictures. It is not uncommon for the viewer to witness scandalous acts and murderous crimes directly. A father assaults his daughters, a naked woman raises her sword at her lover lying helplessly on the ground. But the “perpetrators in the picture” cannot always be clearly identified. And not everything that is immoral or reprehensible is also punishable. With a keen sense of criminology, the authors discuss questions of morality and criminal liability, spanning the art of the 17th century through the avant-garde to the present day.
