What metaphors are used in Tropic of Cancer by Henry Miller?

Paris is a metaphor for art and literature. Paris has long been known as a center for literature and art. This reputation draws Henry to the city, as he tries to become a writer, and he cannot leave Paris for long. The suburbs do not have the same attraction, nor does Dijon. Henry must make his transition in Paris, and after he does, he feels the calm beauty and deep history of the place.
