The dissertation argues that Sam Shepard's plays have an added invisible dimension and attempts to demonstrate this invisibility through a detailed research on his stagecraft, scenography, language, and acting techniques. It ventures to establish that it is Sam Shepard's art to create images through stage, some of which are visible onstage, and others hidden offstage; it is important, the dissertation contends therefore, to look at his plays from the point of view of the audience and reveal the techniques he uses to invoke images in the minds of the viewers.
