Madame Bovary is a novel by Gustave Flaubert that was attacked for obscenity by public prosecutors when it was first serialised in La Revue de Paris between 1 October 1856 and 15 December 1856, resulting in a trial in January 1857 that made it notorious. After the acquittal on 7 February, it became a bestseller in book form in April 1857, and now stands virtually unchallenged not only as a seminal work of Realism, but as one of the most influential novels ever written.
