The document discusses expressionism in theatre and its use in the play Emperor Jones by Eugene O'Neill. Expressionism aims to represent the inner psyche on stage through symbols, short sentences, monologues and other techniques. In Emperor Jones, O'Neill depicts the protagonist Jones regressing into the unconscious levels of his mind as he travels through the jungle after escaping from prison. Jung's theories of the collective unconscious influencing innate human fears through ancestral memories is also discussed. Specific symbols in Emperor Jones like the beating of a tom-tom drum and a fabricated story of a silver bullet represent Jones' increasing fears and his struggle with his racial identity as a black man.
