The work and its context
The museum's open-access catalogue describes the work:
In his series of imaginary prisons, Giovanni Battista Piranesi experimented with scale, perspective, and etching to create disorienting and disturbing images of incarceration. Based on his training as a stage designer rather than on observations of real prisons, Piranesi used a low vantage point and distant staircases to disrupt traditional perspective and to emphasize both the monumentality of the space and the futility of trying to escape. Set against a strange cloud of white smoke, the densely drawn and deeply etched lines of the prisoners at left produce a confusing jumble of bodies that, while imprecise, evoke their pain and punishment.
