Though in looking at nature he was determined to see with his own eyes and not with those of any former master, he found that the science of his predecessors was necessary to him before his sketches could be translated into large pictures. In these pictures his vivid tones and fresh colour are grafted upon the formulae of Claude and Rubens, and it is a common error to regard Constable as an opponent of the great old masters. ”
