This exhibition deliberately makes indeterminacy a key that opens another reading of an entire section of modern and contemporary plastic creation. Initially defined as a loss with respect to the network, the blur turns out to be the preferred means of expression in a world where instability reigns and where visibility has become blurred. Water lilies have long been considered by artists or studied by historians as the model of an abstract, complete and sensitive painting, a harbinger of the great immersive installations to come. On the other hand, the indeterminacy that reigns over the vast aquatic expanses of Monet's large canvases has remained unthinkable. The exhibition will follow a thematic and not chronological thread. An introductory room will be devoted to the aesthetic roots of the blur in the 19th and early 20th centuries, following the intellectual, scientific, social and artistic upheavals with which Impressionism grew.
