Waterloo Bridge, Gray Day

Waterloo Bridge, Gray Day, painted in 1903, belongs to Monet's London Series - the group of nearly 100 canvases he produced during three visits to London between 1899 and 1901. From his room at the Savoy Hotel, Monet painted the Thames, Waterloo Bridge, and the Houses of Parliament under different weather and light conditions, producing serial studies that pushed Impressionism toward the threshold of abstraction. Monet worked on the London paintings in his Giverny studio, using memories and sketches to recreate the atmospheric effects he had observed. The result was a series in which the motif - the bridge, the river, the distant buildings - is progressively absorbed into the enveloping atmosphere of fog, smoke, and colored light. In Waterloo Bridge, Gray Day, the bridge is barely distinguishable from the mist that surrounds it, its arches reduced to grey silhouettes against a sky of pearly luminosity. The London Series represents Impressionism at its most radical: the point where the depiction of specific places gives way to the depiction of transient atmospheric conditions. Monet's fog is not a detail added to a view of the bridge; it is the primary subject, and the bridge exists primarily as a structure within and against which the fog becomes visible.

Monet's London Series demonstrated that serial painting could reveal truths about perception that single images cannot. His method of painting the same motif under different conditions influenced every subsequent artist who used seriality as a means of investigation, from Cezanne's Mont Sainte-Victoire to Warhol's Shadows.

Waterloo Bridge, Gray Day captures the moment when Monet's Impressionism becomes indistinguishable from the atmosphere it depicts. The bridge is not painted through the fog; the fog itself is the painting, and the bridge is merely the scaffold on which it hangs.
