"Having come to Düsseldorf in 1841, Hans Gude became the Calme of the North. Achenbach taught him to approach the phenomenon of nature boldly and realistically, and not to be afraid of a rich and soft scale of colour. Schirmer, the representative of Italian still landscape, guided him to the acquisition of a certain large harmony and sense for style in the structure of his pictures, to beauty of line and effective disposition of great masses of light and shade. This quiet, sure-footed, and robust realism, which had, at the same time, a gift of style, became the chief characteristic of his Northern landscapes, in  which, however, the mutable and fleeting moods of nature were all the more neglected. Here are Norwegian mountain landscapes with lakes, rivers, and waterfalls, then pictures of the shore under the most varied phases of light, or grand cliff scenery with a somber sky and sea in commotion."
