Cox's later work produced after his move to Birmingham in 1841 was marked by simplification, abstraction and a stripping down of detail. His art of the period combined the breadth and weight characteristic of the earlier English watercolour school, together with a boldness and freedom of expression comparable to later impressionism. His concern with capturing the fleeting nature of weather, atmosphere and light was similar to that of John Constable, but Cox stood apart from the older painter's focus on capturing material detail, instead employing a high degree of generalisation and a focus on overall effect.
