Turner, at all events, never came to the conclusion that his knowledge of the sea was complete, for to the end of his life he maintained the freshness and variety of his interpretation. He gave to it, year by year, a deeper note of sentiment, responding always more directly to the impression he received, and eliminating everything that did not help in the attainment of his pictorial purpose. Detail at the last he almost entirely disregarded, concentrating the whole of his attention upon the main effect by which temperamentally he was inspired; but the things essential for the construction of his picture and for making clear the meaning of his motive he observed with the most scrupulous care. Even in his slightest and, seemingly, most casual notes of the sea there was the subtlest accuracy of vision, and there was the truest summing up of the story that was told by the particular phase of the subject he had chosen for the exercise or his powers as an interpreter of nature’s message. Never did he descend to a formula or use a set convention to gain his dramatic result. It was partly for this reason that he stood so sublimely apart from his contemporaries; he did not repeat himself, while they were too often content to follow rules and to do over again things that they had discovered to be attractive to the public. Yet many of the artists of Turner’s period were men of distinction and their sea paintings had satisfying merit and no small measure of inspiration. Stanfield suggested well the movement and action of the sea and was sensitive to its atmosphere; Copley Fielding saw and took the opportunities that the sea offered him for arranging graceful compositions and charming studies of light and shade, and he, too, had a sound understanding of wave movement; De Wint and David Cox, both masterly students of nature, painted the misty subtleties of the coast with masculine power and with the knowledge that comes only from prolonged and thoughtful observation; and others not less observant showed that the pictorial possibilities of the sea had by no means escaped them. But none of them arrived at Turner’s magnificent disregard of limitations or approached him in dramatic strength, and certainly none of them had the courage to abandon, as he did, detailed reality for the sake of presenting a higher and more impressive truth.
