Following the Musée de l'Orangerie's invitation to the artist to enter into a dialogue with Claude Monet's Water Lilies, this book provides a unique opportunity to explore the «last» Nitsch and his elective kinship with the master of Impressionism, who shared his obsession with light and colour. A founder and key figure of Viennese Actionism, Hermann Nitsch (Vienna 1938-Mistelbach 2022) was renowned for his highly radical work, combining painting, music, and performance. His total art culminated in the Orgies Mysteries Theatre, conceived in 1957, a series of festivals and performances inspired by ancient and Christian rites. The last phase of his career saw him embrace a new style of painting characterised by vibrant colours.
