How does Ralph Ellison use imagery in Juneteenth?

In Chapter Sixteen, Ellis' rabbit imagery evolves into the story of Brer Rabbit, as told by Donelson, signifying the filmmaking years of Bliss' life. It is significant that Brer Rabbit turns into a white pearl gun handle, which signifies the period in Bliss' life when he begins to move away from religion into the worldly realm of films and its associated evils and betrayals.
