From a legend most likely invented by Charles Nodier, Gustave Flaubert wrote this remarkable account of truculent romantic resonances around a fatal attraction to books. Bibliomania is an interesting story, full of energy and an exalted romantic vein, which Gustave Flaubert, the future author of Madame Bovary, wrote in his youth. The anecdote of Bibliomanía was suggested to him by a story appeared in a legal magazine that narrated the supposed history of a bookseller assassin of the city of Barcelona. The Barcelona scholar and bibliophile Ramon Miquel i Planas studied in detail the appearance, development and ramifications of this legend of the murderer bookseller, whose intention he attributes to Charles Nodier. This volume includes the version of the legend as presented by Miquel i Planas and the free version that Flaubert made of it.
