Tennessee Williams explores the theme of entrapment and flight through symbolism and motifs that depict a want for escape, relationships that portray entrapment of each other and conventions of a play, such as scenery, stage directions, narrative and dialogue that heighten these ideas as a whole.
The opening scene sketches out the scenery and initial symbol of entrapment for all the characters - the flat which is ‘always burning with the slow implacable fires of human depression’. As Williams describes, the flat is a symbol of depression, formulated by the era the play was set in, the 1930s - just after the Wall St. Crash, in which America suffered great economic depression. The words “burning” and ‘fires’ link into the main symbol that literally attaches itself to the flat: the fire escape. Williams describes it as ‘accidental poetic truth’, telling us that this is not only an escape from tangible fire, but also an escape from the ‘fires of human depression’ - not only the economic depression of society, but in many ways the depression of the Wingfield family themselves. As it is the only entrance into the Wingfield apartment, it is in essence, their only escape.
Williams explores this symbol further through his character Tom, who frequently goes out to smoke on the fire escape in an attempt to escape the reality of his home. For example, in Scene 5, Tom goes outside to smoke and talks to the audience about how the “world was waiting for bombardments” - showing Tom’s desire for adventure - foreshadowing his flight in Scene 7. Opposite to this, showing the difference in character, Laura trips up on the fire escape in Scene 4. This shows how Laura is unable to truly escape the flat and, in many ways, does not seek flight, but is more, hurt when attempting to seek flight. This links into the symbolism of the broken glass unicorn in Scene 7, in which Jim
