Clouds at Sunset, Hudson, New York

Frederic Edwin Church's study captures atmospheric effects over the Hudson River valley in quick, economical strokes. The artist numbers five cloud formations across the composition, annotating their tonal and structural qualities. Church's method—sketching from nature to analyze light and weather patterns—informed his large-scale studio paintings. This working drawing demonstrates the observational practice fundamental to Hudson River School aesthetics, where American landscape painters prioritized direct study of natural phenomena to achieve luminous, dramatic canvases that celebrated the nation's wilderness.
