This book focuses on Romeo Castellucci's theatrical project, exploring the ethical and aesthetic framework determined by his reflection on the nature of the image. But why does a director whose fundamental artistic tool is the image deny this key conceptual notion? Rooted in his conscious distancing from iconoclasm in the 1980s, Castellucci frequently replaces this notion with the words 'symbol', 'form' and 'idea'. As the first publication on the international market which presents Castellucci's work from both historical and theoretical perspectives, this book systematically confronts the director's discourse with other concepts related to his artistic project. Capturing the evolution of his theatre from icon to iconoclasm, word to image and symbol to allegory, the book explores experimental notions of staging alongside an 'emotional wave', which serves as an animating principle of Castellucci's revolutionary theatre.
