Describe symbolism in The Hairy Ape by Eugene O'Neill

There are some significant and important symbols throughout The Hairy Ape. The symbols are employed to reinforce the playwright's ideas and rintentions behind the play. Mildred, with her pure white dress, is a symbol of naivete, an unspotted, pure life. This innocence sinks into the depths of the ship, disrupting the equilibrium that had existed among the firemen.
