This guide offers a unique opportunity to discover the Musée d'Orsay, recognised as the world's largest collection of Impressionist and Post-Impressionistpaintings, with a 360-degree presentation of the works carefully selected to represent the collections and reproduced in this book. Each work is accompanied by a technical sheet and a note written by a curator describing the artist, the context in which it was produced, its description and an aesthetic analysis. This didactic work has become a reference in art history: the works are presented in chronological order, demonstrating the artistic wealth of the period from 1830 to 1930. Whether paintings, sculptures, photographs or objects, these works have earned the institution an international reputation.
