THERE is an enormous difference between a play andany other form of literature. A play is not really apiece of literature for reading. A true play is threedimensional; it is literature that walks and talks before our eyes. It is not intended that the eye shall perceive marks on paper and the imagination turn them into sights, sounds and actions; the text of the play is meant to be translated into sights, sounds and actions which occur literally and physically on a stage. Though in fact plays are often read in silence, if we are to study drama at all intelligently we must always keep this in mind.
