This introduction does an especially good job of finding a reason to even use Longinus. In this case, she cites a critic who uses the word "sublime," and that word then invites us to use Longinus. 

  "Babylon Revisited" is a short story by F. Scott Fitzgerald.  Its central character is Charlie Wales, a recovering alcoholic and recent widower who wants to regain custody of his young daughter, Honoria. Since the death of her mother the girl has lived in Paris with her Aunt Marion, the dead woman's sister. Charlie revisits Paris as a new man, supposedly, and must prove to his in-laws that he is a reformed and suitable father.  The story was first published in the Saturday Evening Post in 1931 and received mediocre reviews. Apparently several critics thought that Fitzgerald was writing about his own life and trying to create sympathy with his readers. Other critics said it was a disappointment compared to his novels or even his previous short stories such as those found in the collection Tales of The Jazz Age. However, this story has demonstrated its staying power by being included in anthologies that are used in both undergraduate and postgraduate levels of study. Does that mean that "Babylon Revisited" is a quality piece of work? Not necessarily, but Julian Evans wrote an article about Fitzgerald in August of 2000 entitled "An American Sublime." In the article she lists several Fitzgerald works that she feels are examples of sublimity, proving the brilliance of the author. She names The Great Gatsby as a primary example, along with two short stories, "Bridal Party" and "Babylon Revisited" (www.newstateman.com). To put "Babylon Revisited" to a more timeless test, one could measure it with Longinus' standards. In "On The Sublime," written about 300 A.D., the theorist states "For by some innate power the true sublime uplifts our souls; we are filled with a proud exaltation and a sense of vaunting joy" (120). Longinus follows this with a list of the five fruitful sources of sublimity.

The first and foremost is the ability to form grand conceptions.  Second comes the stimulus of powerful and inspired emotion. These two elements are very largely innate, while the remainder are the product of art; that is, the proper formation of the two types of figure, figures of thought and figures of speech, together with noble diction. The fifth source of grandeur is dignified and elevated word-arrangement. (121) 

By evaluating "Babylon Revisited" in accordance with Longinus' criteria, we will find that Julian Evans was correct in labeling it a sublime work.
