The definition of Panopticon:
Panopticon is generally the sense that we are always being observed. It is a way to control society. There are more specific examples of Panopticon, for example, times of the gladiator when battles were performed in front of a crowd where death was almost always imminent. The act of putting a prisoner to death in front of numerous observers was another panopticon. So much of everyday was observed. Citizens were under constant social surveillence. Even at inapporpriate times.
