The Magic Skin (La Peau de chagrin) is set in early 19th-century Paris and tells the story of a young man who finds a magic piece of shagreen that fulfills his every desire. For each wish granted, however, the skin shrinks and consumes a portion of his physical energy. Although the novel uses fantastic elements, its main focus is a realistic portrayal of the excesses of bourgeois materialism. Balzac's renowned attention to detail is used to describe a gambling house, an antique shop, a royal banquet, and other locales. He also includes details from his own life as a struggling writer, placing the main character in a home similar to the one he occupied at the start of his literary career. The central theme of La Peau de chagrin is the conflict between desire and longevity. The magic skin represents the owner's life-force, which is depleted through every expression of will, especially when it is employed for the acquisition of power. Ignoring a caution from the shopkeeper who offers him the skin, the protagonist greedily surrounds himself with wealth, only to find himself miserable and decrepit at the story's end.
