Hermann Nitsch is seen as on of the crucial initiators of the Viennese Actionism. Together with Muehl and Frohner he hosted the first theatrical painting actions starting 1960. On his areal in Prinzendorf the "Orgien-Mysterien-Theater"is regularly taking place since 1971. A project that emanates from the idea of a synthesis of the arts and is based on Greek mystery rituals with the goal of a catharsis. Until today this defines Nitsch's artistic work.
