Book excerpt: The Art of Frenzy presents a masterful analysis of public madness from the Renaissance to the Industrial Age. Frenzy--the most flagrant and political form of madness--is the madness of warrior-heroes, kings, scolds, and the possessed. Its representation incorporates a range of traditional characters and figures, from Hercules and Orlando to Medea and Britannia. Understood as abusive power and belligerence out of control, and described in terms drawn equally from definitions of tyranny and liberty, frenzy has always been articulated with a significant degree of political meaning. Integrating art history with cultural studies, political history, and the history of medicine, Jane Kromm draws on a wide range of mediums and contexts--from asylum sculpture to political broadsheets, medical texts, the imagery of revolution, caricature and medical illustrations--to clarify the importance of this interpretative pattern.
