A master thesis Theatre and Madness ? Madman as a Dramatic Image and as a Social Role is exploring changing images of Madman´s image in theatre and drama of western culture, from antic to the modern ages and in relationship to historical, social and cultural contexts. The goal of the thesis is not the complexity of the research. The thesis is merely interested in selected chapters of theatre tradition, that are partially corresponding with personal creative background, particularly with dramaturgy of a John Webster´s play ?The Duchess of Malfi? in Theatre Disk. The work is aspiring for searching and gaining consciousness of roots of this archetypal image, which is standing at a beginning of theatre creation and represents its deep source and possible danger. This image is intended to be magically fulfilled and overreached by its description.
