The symbolic character of a work of art must not be lost from sight, for it is the clue to the interpretation of pictures, as it is of all art. The painter feels his way through the gamut of his palette to a harmony of color just as truly as the musician summons the notes of his scale and marshals them into accord. The painter is moved by some sweep of landscape; it wakens in him an emotion. When he sets himself to express his emotion in the special medium with which he works, he represents by pigment the external aspect of the landscape, yes; but not in order to imitate it or reproduce it: he represents the landscape because the colors and the forms which he registers upon the canvas express for him the emotions roused by those colors and those forms in nature. He does not try to match his grays with nature's grays, but this nuance which he gropes for on his palette, and having found it, touches upon his canvas, expresses for him what that particular gray in nature made him feel. His one compelling purpose is in all fidelity and singleness of aim to "translate the impression received." The painter's medium is just as symbolic as the notes of the musician's nocturne or the words of the poet's sonnet, equally inspired by the hour and place. Color and line and form, although they happen to be the properties of _things,_ have a value for the emotions as truly as musical sounds: they are the outward symbol of the inward thought or feeling, the visible bodying forth of the immaterial idea. The symbolic character of the material world is not early apprehended. In superficial reaction upon life, men do not readily pass beyond the immediate actuality. That the spiritual meaning of all things is not perceived, that all things are not seen to be beautiful, or expressive of the supreme harmony, is due to men's limited powers of sight and feeling. Therefore is it that the artist is given in order that he may reveal as yet unrealized spiritual relations, or new beauty. The workaday world with its burden of exigent "realities" has need of a Carlyle to declare that things are but a wonderful metaphor and the physical universe is the garment of the living God. In the realm of thought an Emerson, seer of transcendent vision, must come to restore his fellows to their birthright, which is the life of the spirit. As in life, so in art men do not easily pass the obvious and immediate. The child reads "Gulliver's Travels" or "The Pilgrim's Progress" for the story. As his experience of life both widens and deepens, he is able to see through externals, and he penetrates to the real significance, of which the narrative is but the symbol. So it is with an insight born of experience that the lover of art sees no longer the "subject," but the beauty which the subject is meant to symbolize.
