Relatively few works by Balzac can bear comparison with Illusions perdues [Lost Illusions] for its overall scope and chronological span, or for its range of themes, characters and stylistic registers. This blockbuster of a story is, in effect, a trilogy of novels that were first written separately (Illusions perdues, 1837; Un Grand home de province à Paris, 1839; Eve et David, 1843). They were then brought together and reworked into a single text in three parts, under the title Illusions perdues, for the collective edition of Balzac's works in 1843 that was to be entitled
