First Chorister:  It's a coup d'état! The overthrow of the state! 
Second Chorister: It certainly sounds that way, but how can we know?
First Chorister:  We could go and see?
Second Chorister:                   We can't. We're only the chorus.
               We can never leave this space. It's one of the rules.

—Aeschylus, Agamemnon [Lines 1138–1141]
