Landscape with a Stormy Sky

Rousseau's Landscape with a Stormy Sky from around 1842 captures the dramatic atmospheric conditions that he considered among the most revealing tests of a landscape painter's observational power. Storms were among the most dynamic and transient of natural phenomena — the specific quality of a storm's light, the weight of its clouds, the particular green of vegetation before rainfall — demanded rapid and accurate observation that left no room for compositional invention or academic formula. Rousseau painted outdoors in all conditions, developing the meteorological sensitivity that the Barbizon painters shared with John Constable and that would pass directly to the Impressionists. This stormy landscape demonstrates his mastery of dark, heavy cloud formations and the theatrical light they create.

Rousseau's oil-on-canvas technique employs rich, dark tones and vigorous brushwork to capture the turbulent sky and the landscape responding to the approaching storm. The dramatic contrasts of light and shadow create the emotional intensity that defines his most powerful landscape paintings.
