A rainbow arcs across the sky, cutting through a mass of dark clouds and mist that hovers over a mountainous landscape. The scene is dominated by towering peaks on either side, their slopes shrouded in shadow and haze, with a soft glow breaking through the centre where the light touches the valley. A tranquil lake stretches across the lower half of the composition, its surface reflecting the muted tones of the sky and the surrounding hills.

Near the centre foreground, a small boat with two figures floats on the water, dwarfed by the vastness of nature around them. The vegetation in the foreground is rendered with loose, textured brushstrokes, giving a sense of wild growth and movement at the water’s edge. The palette is dominated by earthy browns, deep greens, and smoky blues, punctuated by the pale, luminous arc of the rainbow and the golden light that breaks through the clouds.

Soft, atmospheric effects are achieved with blended, almost vaporous paint handling, especially in the sky and distant mountains, while sharper lines and darker tones define the nearer forms. In the lower left corner, tangled branches and undergrowth are painted in dark, jagged strokes, creating a dense thicket at the water’s edge. The upper right corner of the painting is filled with deep shadow, where the mountain slopes blend into the overcast sky.

The water in the foreground reflects subtle hints of green and gold, picking up the colors of the vegetation and the filtered sunlight above. The rainbow’s arc is rendered with a soft, diffused edge, and its colors gently merge into the surrounding mist and cloud, enhancing the atmospheric quality of the scene. Buttermere Lake, with Park of Cromackwater, Cumberland, a Shower is created by Joseph Mallord William Turner in the 1790s. The title locates the view at Buttermere Lake in Cumberland, with a reference to a shower, which is visually echoed by the presence of the rainbow and the shifting weather depicted in the scene.
