By William Shakespeare

 

Elizabethan stages did not use scenery.

 Acknowledging the difficulty of conveying great battles and shifts of location on a bare stage, the chorus calls for a "Muse of fire" so that the actor playing King Henry can "Assume the port of Mars."

 

He asks, "Can this cockpit [i.e. the theatre] hold / The vasty fields of France?" and encourages the audience to use their imaginations to overcome the stage's limitations: "Piece out our imperfections with your thoughts."
