Until then the story had been confined to the portrayal of a unique passion, love, but love in an ideal sphere and outside of the necessities and miseries of life. The personages of these entirely psychological recitals neither ate, nor drank, nor lodged, nor had an account with their tailor. They moved in an abstract environment like those of a tragedy. If they wished to travel, they put, without obtaining a passport, some handfuls of diamonds into the bottom of their pocket, and paid with this currency the postilions, who did not fail at each way station to have exhausted their horses; some chateaus of indistinct architecture received them at the end of their journeys, and with their blood they wrote to their beloveds interminable epistles dated from the tour of the North. The heroines, no less immaterial, resembled an aquatint of Angelica Kauffmann: a large straw hat, hair somewhat straightened in the English style, a long robe of white chiffon, held at the waist by an azure sash. With his profound instinct for reality, Balzac understood that the modern life he wanted to portray was dominated by one grand fact, money, and, in La Peau de Chagrin, he had the courage to present a lover not only anxious to know if he had touched the heart of the one he loves, but also if he will have enough money to pay for the carriage in which he was bringing her home. This audacity is perhaps one of the greatest that one might permit oneself in literature, and it alone sufficed to immortalize Balzac. The consternation was profound, and the purists were indignant at this infraction of the laws of the genre; but all the young people who, going out in the evening to the home of some beautiful woman wearing white gloves ironed with gum elastic, had traversed Paris as dancers, on the tips of their shoes, fearing a spot of mud more than the crack of a pistol, commiserated, having shared these fears, like the anguishes of Valentin, who cared deeply about a hat that he could not renew and preserve despite his minute care. In moments of supreme misery, the discovery of a one hundred sou piece slid under the papers of the drawer, due to the discreet pity of Pauline, produced the effect of the most romantic theatrical strokes or of the intervention of a Peri in the Arabian tales. Who has not discovered during days of distress, forgotten in pants or in a vest, a few glorious coins appearing at just the right time and saving you from the calamity that youth fears the most: to fail to provide a beloved woman with a carriage, a bouquet, a small bench, a show program, a tip to the usherette or some trifles of this type?
