CIRCA aims to make clowning dangerous again, to bring it back to the street, restore its disobedience and give it back the social function it once had: its ability to disrupt, critique and heal society. Since the beginning of time tricksters (the mythological origin or all clowns) have embraced life's paradoxes, creating coherence through confusion — adding disorder to the world in order to expose its lies and speak the truth.
