I discovered this gem of a sketch in an E. H. Gombrich essay from 1988. "In the masterly landscape drawings of Rembrandt the stroke is invariably adapted to the motif." It's easy to see why Rembrandt is widely admired to this day; his sketches are much more than pretty pictures, even to jaded contemporary eyes. I especially admire the rhythmic progression of horizontals in this sketch. The wash hung out to dry is a marvelous detail, tucked into the darker area of shadow.
