But compared with his landscape, in which he is unique, it is plain that he excels nowhere else. The splendid display of his works in the Centenaire Exposition of the great World's Fair of 1889, was a revelation of his range of interest rather than of his range of power. It was impossible not to perceive that, surprising as were his essays in other fields to those who only knew him as a landscape painter, he was essentially and integrally a painter of landscape, though a painter of landscape who had taken his subject in a way and treated it in a manner so personal as to be really unparalleled. Outside of landscape his interest was clearly not real. In his other works one notes a certain débonnaire irresponsibility. He pursued nothing seriously but out-of-doors, its vaporous atmosphere, its crisp twigs and graceful branches, its misty distances and piquant accents, what Thoreau calls its inaudible panting. His true theme, lightly as he took it, absorbed him; and no one of any sensitiveness can ever regret it. His powers, following the indication of his true temperament, his most genuine inspiration, are concentrated upon the very finest thing imaginable in landscape painting; as, indeed, to produce as they have done the finest landscape in the history of art, they must have been.
There are, however, two things worth noting in Corot's landscape, beyond the mere fact that, better even than Rousseau, he expresses the essence of landscape, dwells habitually among its inspirations, and is its master rather than its servant. One is the way in which he poetizes, so to speak, the simplest stretches of sward and clumps of trees, and long clear vistas across still ponds, with distances whose accents are pricked out with white houses and yellow cows and placid fishers and ferrymen in red caps, seen in glimpses through curtains of sparse, feathery leafage—or peoples woodland openings with nymphs and fawns, silhouetted against the sunset glow, or dancing in the cool gray of dusk. A man of no reading, having only the elements of an education in the general sense of the term, his instinctive sense for what is refined was so delicate that we may say of his landscapes that, had the Greeks left any they would have been like Corot's. And this classic and cultivated effect he secured not at all, or only very incidentally, through the force of association, by dotting his hillsides and vaporous distances with bits of classic architecture, or by summing up his feeling for the Dawn in a graceful figure of Orpheus greeting with extended gesture the growing daylight, but by a subtle interpenetration of sensuousness and severity resulting in precisely the sentiment fitly characterized by the epithet classic. The other trait peculiar to Corot's representation of nature and expression of himself is his color. No painter ever exhibited, I think, quite such a sense of refinement in so narrow a gamut. Green and gray, of course, predominate and set the key, but he has an interestingly varied palette on the hither side of splendor whose subtleties are capable of giving exquisite pleasure. Never did anyone use tints with such positive force. Tints with Corot have the vigor and vibration of positive colors—his lilacs, violets, straw-colored hues, his almost Quakerish coquetry with drabs and slates and pure clear browns, the freshness and bloom he imparted to his tones, the sweet and shrinking wild flowers with which as a spray he sprinkled his humid dells and brook margins. But Corot's true distinction—what gives him his unique position at the very head of landscape art, is neither his color, delicate and interesting as his color is, nor his classic serenity harmonizing with, instead of depending upon, the chance associations of architecture and mythology with which now and then he decorates his landscapes; it is the blithe, the airy, the truly spiritual way in which he gets farther away than anyone from both the actual pigment that is his instrument, and from the phenomena that are the objects of his expression—his ethereality, in a word. He has communicated his sentiment almost without material, one may say, so ethereally independent of their actual analogues is the interest of his trees and sky and stretch of sward. This sentiment, thus mysteriously triumphant over color or form, or other sensuous charm, which nevertheless are only subtly subordinated, and by no manner of means treated lightly or inadequately, is as exalted as any that has in our day been expressed in any manner. Indeed, where, outside of the very highest poetry of the century, can one get the same sense of elation, of aspiring delight, of joy unmixed with regret—since "the splendor of truth" which Plato defined beauty to be, is more animating and consoling than the "weary weight of all this unintelligible world," is depressing to a spirit of lofty seriousness and sanity?
Dupré and Diaz are the decorative painters of the Fontainebleau group. They are, of modern painters, perhaps the nearest in spirit to the old masters, pictorially speaking. They are rarely in the grand style, though sometimes Dupré is restrained enough to emulate if not to achieve its sobriety. But they have the bel air, and belong to the aristocracy of the painting world. Diaz, especially, has almost invariably the patrician touch. It lacks the exquisiteness of Monticelli's, in which there is that curiously elevated detachment from the material and the real that the Italians—and the Provençal painter's inspiration and method, as well as his name and lineage, suggest an Italian rather than a French association—exhibit far oftener than the French. But Diaz has a larger sweep, a saner method. He is never eccentric, and he has a dignity that is Iberian, though he is French rather than Spanish on his æsthetic side, and at times is as conservative as Rousseau—without, however, reaching Rousseau's lofty simplicity except in an occasional happy stroke. Both he and Dupré are primarily colorists. Dupré sees nature through a prism. Diaz's groups of dames and gallants have a jewel-like aspect; they leave the same impression as a tangle of ribbons, a bunch of exotic flowers, a heap of gems flung together with the felicity of haphazard. In general, and when they are in most completely characteristic mood, it is not the sentiment of nature that one gets from the work of either painter. It is not even their sentiment of nature—the emotion aroused in their susceptibilities by natural phenomena. What one gets is their personal feeling for color and design—their decorative quality, in a word.
The decorative painter is he to whom what is called "subject," even in its least restricted sense and with its least substantial suggestions, is comparatively indifferent. Nature supplies him with objects; she is not in any intimate degree his subject. She is the medium through which, rather than the material of which, he creates his effects. It is her potentialities of color and design that he seeks, or at any rate, of all her infinitely numerous traits, it is her hues and arabesques that strike him most forcibly. He is incurious as to her secrets and calls upon her aid to interpret his own, but he is so independent of her, if he be a decorative painter of the first rank—a Diaz or a Dupré—that his rendering of her, his picture, would have an agreeable effect, owing to its design or color or both, if it were turned upside down. Decorative painting in this sense may easily be carried so far as to seem incongruous and inept, in spite of its superficial attractiveness. The peril that threatens it is whim and freak. Some of Monticelli's, some of Matthew Maris's pictures, illustrate the exaggeration of the decorative impulse. After all, a painter must get his effect, whatever it be and however it may shun the literal and the exact, by rendering things with pigments. And some of the decorative painters only escape things by obtruding pigments, just as the trompe-l'oeil or optical illusion painters get away from pigments by obtruding things. It is the distinction of Diaz and Dupré that they avoid this danger in most triumphant fashion. On the contrary, they help one to see the decorative element in nature, in "things," to a degree hardly attained elsewhere since the days of the great Venetians. Their predilection for the decorative element is held in leash by the classic tradition, with its reserve, its measure, its inculcation of sobriety and its sense of security. Dupré paints Seine sunsets and the edge of the forest at Fontainebleau, its "long mysterious reaches fed with moonlight," in a way that conveys the golden glow, the silvery gleam, the suave outline of spreading leafage, and the massive density of mysterious boscage with the force of an almost abstract acuteness. Does nature look like this? Who knows? But in this semblance, surely, she appeared to Dupré's imagination. And doubtless Diaz saw the mother-of-pearl tints in the complexion of his models, and is not to be accused of artificiality, but to be credited with a true sincerity of selection in juxtaposing his soft corals and carnations and gleaming topaz, amethyst, and sapphire hues. The most exacting literalist can hardly accuse them of solecism in their rendering of nature, true as it is that their decorative sense is so strong as to lead them to impose on nature their own sentiment instead of yielding themselves to absorption in hers, and thus, in harmonious and sympathetic concert with her, like Claude and Corot, Rousseau and Daubigny, interpreting her subtle and supreme significance.
Rousseau carried the fundamental principle of the school farther than the others—with him interest, delight in, enthusiasm for nature became absorption in her. Whereas other men have loved nature, it has been acutely remarked, Rousseau was in love with her. It was felicitously of him, rather than of Dupré or Corot, that the naif peasant inquired, "Why do you paint the tree; the tree is there, is it not?" And never did nature more royally reward allegiance to her than in the sustenance and inspiration she furnished for Rousseau's genius. You feel the point of view in his picture, but it is apparently that of nature herself as well as his own. It is not the less personal for this. On the contrary, it is extremely personal, and few pictures are as individual, as characteristic. Occasionally Diaz approaches him, as I have said, but only in the very happiest and exceptional moments, when the dignity of nature as well as her charm seems specially to impress and impose itself upon the less serious painter. But Rousseau's selection seems instinctive and not sought out. He knows the secret of nature's pictorial element. He is at one with her, adopts her suggestions so cordially and works them out with such intimate sympathy and harmoniousness, that the two forces seem reciprocally to reinforce each other, and the result gains many fold in power from their subtle co-operation. His landscapes have in this way a Wordsworthian directness, simplicity, and severity. They are not troubled and dramatic like Turner's. They are not decorative like Dupré's, they have not the solemn sentiment of Daubigny's, or the airy aspiration and fairy-like blitheness of Corot's. But there is in them "all breathing human passion;" and at times, as in "Le Givre," they rise to majesty and real grandeur because they are impregnated with the sentiment, as well as are records of the phenomena, of nature, and one may say of Rousseau, paraphrasing Mr. Arnold's remark about Wordsworth, that nature seems herself to take the brush out of his hand and to paint for him "with her own bare, sheer, penetrating power." Rousseau, however, is French, and in virtue of his nativity exhibits always what Wordsworth's treatment of nature exhibits only occasionally, namely, the Gallic gift of style. It is rarely as felicitous as in Corot, in every detail of whose every work, one may almost say, its informing, co-ordinating, elevating influence is distinctly to be perceived; but it is always present as a factor, as a force dignifying and relieving from all touch, all taint of the commonness that is so often inseparably associated with art whose absorption in nature is listlessly unthinking instead of enthusiastic and alert. In Rousseau, too, in a word, we have the classic strain, as at least a psychological element, and note as one source of his power his reserve and restraint, his perfect self-possession.
In Daubigny a similar attitude toward nature is obvious, but with a sensible difference. Affection for, rather than absorption in her, is his inspiration. Daubigny stands somewhat apart from the Fontainebleau group, with whom nevertheless he is popularly and properly associated, for though he painted Normandy mainly, he was spiritually of the Barbizon kindred. He stands, however, somewhat apart from French painting in general, I think. There is less style, more sentiment, more poetry in his landscapes than in those of his countrymen who are to be compared with him. Beyond what is admirable in them there is something attaching as well. He drew and engraved a good deal, as well as painted. He did not concentrate his powers enough, perhaps, to make as signal and definite a mark as otherwise he might have done. He is a shade desultory, and too spontaneous to be systematic. One must be systematic to reach the highest point, even in the least material spheres. But never have the grave and solemn aspects of landscape found a sweeter and serener spirit to interpret them. In some of his pictures there is a truly religious feeling. His frankness recalls Constable's, but it is more distinguished in being more spiritual. He has not Diaz's elegance, nor Corot's witchery, nor Rousseau's power, but nature is more mysteriously, more mystically significant to him, and sets a deeper chord vibrating within him. He is a sensitive instrument on which she plays, rather than a magician who wins her secrets, or an observer whose generalizing imagination she sets in motion. The design of some of his important works, notably that of his last Salon picture, is very distinguished, and in one of his large canvases representing a road like that from Barbizon through the level plain to Chailly, there is the spirit and sentiment of all the summer evenings that ever were. But he has distinctly less power than the strict Fontainebleau group. He has, in force, less affinity with them than Troyon has, whose force is often magnificent, and whose landscape is so sweet, often, and often so strong as well, that one wonders a little at his fondness for cattle—in spite of the way in which he justifies it by being the first of cattle painters. And neither Daubigny nor Troyon, nor, indeed, Rousseau himself, often reaches in dramatic grandeur the lofty landscape of Michel, who, with Paul Huet (the latter in a more strictly historical sense) were so truly the forerunners and initiators of the romantic landscape movement, both in sentiment and chronology, in spite of their Dutch tradition, as to make the common ascription of its debt to Constable, whose aid was so cordially welcomed in the famous Salon of 1824, a little strained.
