This model was a prize winner in the Unknown Political Prisoner competition. Pevsner compared the Parthenon in Athens as a symbol of wisdom with the competition as a symbol of moral rebirth. He therefore sought a form for his monument that was 'plastic, architectonic and sculptural'. The monument was to be seen in its entirety from any direction. Pevsner made a full scale sculpture in bronze from this model in 1955-6. It belongs to the French National Museum of Modern Art in Paris. The model here, though somewhat simplified, indicates the surface complexity of the finished version, whose outer sides are filled in with sheet metal. The central spherical image represents captivity.
