* "The air was thick with unseen, unmoving things." This metaphor describes the oppressive atmosphere of Paris, suggesting a sense of weight and heaviness that reflects the protagonist's (Charlie Wales') emotional state. It also evokes a feeling of unseen dangers or hidden burdens.
* "He felt that Paris was like a woman he had loved long ago, but who was now dead." This metaphor compares Paris to a lost love, emphasizing Charlie's sense of nostalgia and loss. The city, once a symbol of excitement and freedom, now represents a past he can no longer recapture.
* "He was a man who had been through a great deal and had come out of it with a certain amount of scar tissue." This metaphor suggests that Charlie has been deeply wounded by his past experiences. The "scar tissue" represents the emotional damage he carries with him, despite his attempts to move on.
* "The hotel was a place where people went to forget, or to remember, or to try to recapture something they had lost." This metaphor describes the hotel as a place where people seek solace or escape from their past. It suggests that the hotel is a microcosm of life itself, where people grapple with their memories and desires.
These are just a few examples of the many metaphors Fitzgerald employs in "Babylon Revisited." They help to create a rich and layered meaning, adding depth and complexity to the story's themes of loss, regret, and the fleeting nature of pleasure.
