Llanberis Lake, North Wales

Jackson belonged to a loosely associated group of artists known as the Bristol School. When his father's business closed in 1820, he became a drawing master, helped to organize an exhibition at the Bristol Institution in 1824, and joined the Bristol Society of Artists. Influenced by Francis Danby at the outset, Jackson developed a distinct individual style after his mentor moved to London in 1824. To establish a national reputation, Jackson joined London's Old Water-Colour Society in 1823, and sent works to the group's annual exhibitions through 1848. This Welsh mountain view demonstrates a mature, sophisticated technique, with sponging, stopping, scratching and glazing used to evoke shifting tones and atmospheric effects. A colored version of the subject is at the Victoria and Albert Museum in London.
