The Italian theatre company Socìetas Raffaello Sanzio, led by Romeo Castellucci, began its passionate incursion into Italian theatre in the 1980s. Through an analysis of their most challenging critical texts and manifestos, as yet unpublished in English, this paper will examine the theoretical foundations of Socìetas Raffaello Sanzio's oeuvre and the profound implications of the iconoclasm of their performances, and propose new means of deciphering their work. During the 1980s the company forged new linguistic and visual theatrical techniques, which were further developed through the 2002–2004 project, Tragedia Endogonidia. I argue that the relevance of their early work lies in their theoretical and practical widening of the parameters of representation. Excerpts from manifestos and texts written by Romeo and Claudia Castellucci, along with critical texts related to their work, are unless otherwise indicated translated into English by the present author.
