The origins of the Western theatre have been built on the ritual of ancient theatre, as Florence Dupont reminds us. However this dimension which was left behind by the classical and modern theater has been replaced by new agreements. As they appear to be primarily social there is nothing ritual in these new rites anymore. Theatre is now desecrated and appears as the prerogative of a bourgeois society reinventing its cultural and societal code. The separation that was consumed by the famous fourth wall resulted in the twentieth century research renewal links between the performance hall and the stage. They actually went through a stepping outside the framework and the reinvention of a game which, in Guy Debord’s footsteps, denounces the “society of the spectacle”. The adjustment between the theatre reference frames and the need for community sharing, on both sides of the house, highlights the “games” in the functional sense, i.e the flaws or the assets that result from it. A “game between the boards” has set itself in the theater, as a palimpsest of the lost ritual.
