The two-volume work provides comprehensive information about artistic reactions to the Prinzhorn Collection, from the beginnings of the collection in 1919-1921 to the present day. It reflects on a significant aspect of the ten-year museum activity in Heidelberg, which spans from the exhibitions 'Expressionism and Madness' (2005), 'Surrealism and Madness' (2009/2010), and a series of monographic cabinet exhibitions to the anniversary exhibition 'From Kirchner to the Present - Artists Respond to the Prinzhorn Collection.' Additionally, there are occasional performances of musical interpretations during exhibition openings or in separate concerts. One of the volumes presents reactions in the field of visual arts, while the other focuses on literary and musical responses. Alongside good illustrations and detailed documentation of Heidelberg.
