by Pyotr Pavlensky. In the early hours of Oct. 16, 2017, Pavlensky set fire to the ground-floor windows of a branch of the Banque de France on the Place de la Bastille. “Institutions of power are oppressive, yet they are also oddly vulnerable to someone who denies their legitimacy. He is now at work documenting the government’s contribution to ‘Lighting’ — the CCTV images, court transcripts, letters from the prison authorities that constitute the larger artwork. All his work, Pavlensky says, reveals that society at large may be a prison, but it is still possible to exert a kind of negative liberty.”
