But perhaps the most grievous fault of all, in the clouds of these painters, is the utter want of transparency. Not in her most ponderous and lightless masses will nature ever leave us [§ 14. Total want of transparency and evanescence in the clouds of ancient landscape.]without some evidence of transmitted sunshine; and she perpetually gives us passages in which the vapor becomes visible only by the sunshine which it arrests and holds within itself, not caught on its surface, but entangled in its mass—floating fleeces, precious with the gold of heaven; and this translucency is especially indicated on the dark sides even of her heaviest wreaths, which possess opalescent and delicate hues of partial illumination, far more dependent upon the beams which pass through them than on those which are reflected upon them. Nothing, on the contrary, can be more painfully and ponderously opaque than the clouds of the old masters universally. However far removed in aerial distance, and however brilliant in light, they never appear filmy or evanescent, and their light is always on them, not in them. And this effect is much increased by the positive and persevering determination on the part of their outlines not to be broken in upon, nor interfered with in the slightest degree, by any presumptuous blue, or impertinent winds. There is no inequality, no variation, no losing or disguising of line, no melting into nothingness, nor shattering into spray; edge succeeds edge with imperturbable equanimity, and nothing short of the most decided interference on the part of tree-tops, or the edge of the picture, prevents us from being able to follow them all the way round, like the coast of an island.

And be it remembered that all these faults and deficiencies are to be found in their drawing merely of the separate masses of the solid cumulus, the easiest drawn of all clouds. But [§ 15. Farther proof of their deficiency in space.]nature scarcely ever confines herself to such masses; they form but the thousandth part of her variety of effect. She builds up a pyramid of their boiling volumes, bars this across like a mountain with the gray cirrus, envelops it in black, ragged, drifting vapor, covers the open part of the sky with mottled horizontal fields, breaks through these with sudden and long sunbeams, tears up their edges with local winds, scatters over the gaps of blue the infinity of multitude of the high cirri, and melts even the unoccupied azure into palpitating shades. And all this is done over and over again in every quarter of a mile. Where Poussin or Claude have three similar masses, nature has fifty pictures, made up each of millions of minor thoughts—fifty aisles penetrating through angelic chapels to the Shechinah of the blue—fifty hollow ways among bewildered hills—each with their own nodding rocks, and cloven precipices, and radiant summits, and robing vapors, but all unlike each other, except in beauty, all bearing witness to the unwearied, exhaustless operation of the Infinite Mind. Now, in cases like these especially, as we observed before of general nature, though it is altogether hopeless to follow out in the space of any one picture this incalculable and inconceivable glory, yet the painter can at least see that the space he has at his command, narrow and confined as it is, is made complete use of, and that no part of it shall be without entertainment and food for thought. If he could subdivide it by millionths of inches, he could not reach the multitudinous majesty of nature; but it is at least incumbent upon him to make the most of what he has, and not, by exaggerating the proportions, banishing the variety and repeating the forms of his clouds, to set at defiance the eternal principles of the heavens—fitfulness and infinity. And now let us, keeping in memory what we have seen of Poussin and Salvator, take up one of Turner's skies, and see whether he is as narrow [§ 16. Instance of perfect truth in the sky of Turner's Babylon.]in his conception, or as niggardly in his space. It does not matter which we take, his sublime Babylon[[33]] is a fair example for our present purpose. Ten miles away, down the Euphrates, where it gleams last along the plain, he gives us a drift of dark elongated vapor, melting beneath into a dim haze which embraces the hills on the horizon. It is exhausted with its own motion, and broken up by the wind in its own body into numberless groups of billowy and tossing fragments, which, beaten by the weight of storm down to the earth, are just lifting themselves again on wearied wings, and perishing in the effort. Above these, and far beyond them, the eye goes back to a broad sea of white, illuminated mist, or rather cloud melted into rain, and absorbed again before that rain has fallen, but penetrated throughout, whether it be vapor or whether it be dew, with soft sunshine, turning it as white as snow. Gradually as it rises, the rainy fusion ceases, you cannot tell where the film of blue on the left begins—but it is deepening, deepening still,—and the cloud, with its edge first invisible, then all but imaginary, then just felt when the eye is not fixed on it, and lost when it is, at last rises, keen from excessive distance, but soft and mantling in its body, as a swan's bosom fretted by faint wind, heaving fitfully against the delicate deep blue, with white waves, whose forms are traced by the pale lines of opalescent shadow, shade only because the light is within it, and not upon it, and which break with their own swiftness into a driven line of level spray, winnowed into threads by the wind, and flung before the following vapor like those swift shafts of arrowy water which a great cataract shoots into the air beside it, trying to find the earth. Beyond these, again, rises a colossal mountain of gray cumulus, through whose shadowed sides the sunbeams penetrate in dim, sloping, rain-like shafts; and over which they fall in a broad burst of streaming light, sinking to the earth, and showing through their own visible radiance the three successive ranges of hills which connect its desolate plain with space. Above, the edgy summit of the cumulus, broken into fragments, recedes into the sky, which is peopled in its serenity with quiet multitudes of the white, soft, silent cirrus; and under these again, drift near the zenith, disturbed and impatient shadows of a darker spirit, seeking rest and finding none.

Now this is nature! It is the exhaustless living energy with which the universe is filled; and what will you set beside it of the works of other men? Show me a single picture, in the [§ 17. And in his Pools of Solomon.]whole compass of ancient art, in which I can pass from cloud to cloud, from region to region, from first to second and third heaven, as I can here, and you may talk of Turner's want of truth. Turn to the Pools of Solomon, and walk through the passages of mist as they melt on the one hand into those stormy fragments of fiery cloud, or, on the other, into the cold solitary shadows that compass the sweeping hill, and when you find an inch without air and transparency, and a hairbreadth without changefulness and thought; and when you can count the torn waves of tossing radiance that gush from the sun, as you can count the fixed, white, insipidities of Claude; or when you can measure the modulation and the depth of that hollow mist, as you can the flourishes of the brush upon the canvas of Salvator, talk of Turner's want of truth!

But let us take up simpler and less elaborate works, for there is too much in these to admit of being analyzed.

In the vignette of the Lake of Como, in Rogers's Italy, the space is so small that the details have been partially lost by the engraver; but enough remain to illustrate the great principles [§ 18. Truths of outline and character in his Como.]of cloud from which we have endeavored to explain. Observe first the general angular outline of the volumes on the left of the sun. If you mark the points where the direction of their outline changes, and connect those points by right lines, the cloud will touch, but will not cut, those lines throughout. Yet its contour is as graceful as it is full of character—toppling, ready to change—fragile as enormous—evanescent as colossal. Observe how, where it crosses the line of the sun, it becomes luminous, illustrating what has been observed of the visibility of mist in sunlight. Observe, above all, the multiplicity of its solid form, the depth of its shadows in perpetual transition: it is not round and swelled, half light and half dark, but full of breaking irregular shadow and transparency—variable as the wind, and melting imperceptibly above into the haziness of the sunlighted atmosphere, contrasted in all its vast forms with the delicacy and the multitude of the brightly touched cirri. Nothing can surpass the truth of this; the cloud is as gigantic in its simplicity as the Alp which it opposes; but how various, how transparent, how infinite in its organization!

I would draw especial attention, both here and in all other works of Turner, to the beautiful use of the low horizontal bars or fields of cloud, (cirrostratus,) which associate themselves so [§ 19. Association of the cirrostratus with the cumulus.]frequently—more especially before storms—with the true cumulus, floating on its flanks, or capping it, as if it were a mountain, and seldom mingling with its substance, unless in the very formation of rain. They supply us with one of those beautiful instances of natural composition, by which the artist is superseded and excelled—for, by the occurrence of these horizontal flakes, the rolling form of the cumulus is both opposed in its principal lines, and gifted with an apparent solidity and vastness, which no other expedient could have exhibited, and which far exceed in awfulness the impression of the noblest mountains of the earth. I have seen in the evening light of Italy, the Alps themselves out-towered by ranges of these mighty clouds, alternately white in the starlight, and inhabited by fire.

Turn back to the first vignette in the Italy. The angular outlines and variety of modulation in the clouds above the sail, and the delicate atmosphere of morning into which they are [§ 20. The deep-based knowledge of the Alps in Turner's Lake of Geneva.]dissolved about the breathing hills, require no comment; but one part of this vignette demands especial notice; it is the repetition of the outline of the snowy mountain by the light cloud above it. The cause of this I have already explained (vide [page 228],) and its occurrence here is especially valuable as bearing witness to the thorough and scientific knowledge thrown by Turner into his slightest works. The thing cannot be seen once in six months; it would not have been noticed, much less introduced by an ordinary artist, and to the public it is a dead letter, or an offence. Ninety-nine persons in a hundred would not have observed this pale wreath of parallel cloud above the hill, and the hundredth in all probability says it is unnatural. It requires the most intimate and accurate knowledge of the Alps before such a piece of refined truth can be understood.

At the 216th page we have another and a new case, in which clouds in perfect repose, unaffected by wind, or any influence but that of their own elastic force, boil, rise, and melt in the [§ 21. Further principles of cloud form exemplified in his Amalfi.]heaven with more approach to globular form than under any other circumstances is possible. I name this vignette, not only because it is most remarkable for the buoyancy and elasticity of inward energy, indicated through the most ponderous forms, and affords us a beautiful instance of the junction of the cirrostratus with the cumulus, of which we have just been speaking (§ 19,) but because it is a characteristic example of Turner's use of one of the facts of nature not hitherto noticed, that the edge of a partially transparent body is often darker than its central surface, because at the edge the light penetrates and passes through, which from the centre is reflected to the eye. The sharp, cutting edge of a wave, if not broken into foam, frequently appears for an instant almost black; and the outlines of these massy clouds, where their projecting forms rise in relief against the light of their bodies, are almost always marked clearly and firmly by very dark edges. Hence we have frequently, if not constantly, multitudinous forms indicated only by outline, giving character and solidity to the great masses of light, without taking away from their breadth. And Turner avails himself of these boldly and constantly,—outlining forms with the brush of which no other indication is given. All the grace and solidity of the white cloud on the right-hand side of the vignette before us, depends upon such outlines.

As I before observed of mere execution, that one of the best tests of its excellence was the expression of infinity; so it may be noticed with respect to the painting of details generally, [§ 22. Reasons for insisting on the infinity of Turner's works. Infinity is almost an unerring test of all truth.]that more difference lies between one artist and another, in the attainment of this quality, than in any other of the efforts of art; and that if we wish, without reference to beauty of composition, or any other interfering circumstances, to form a judgment of the truth of painting, perhaps the very first thing we should look for, whether in one thing or another—foliage, or clouds, or waves—should be the expression of infinity always and everywhere, in all parts and divisions of parts. For we may be quite sure that what is not infinite, cannot be true; it does not, indeed, follow that what is infinite, always is true, but it cannot be altogether false, for this simple reason; that it is impossible for mortal mind to compose an infinity of any kind for itself, or to form an idea of perpetual variation, and to avoid all repetition, merely by its own combining resources. The moment that we trust to ourselves, we repeat ourselves, and therefore the moment we see in a work of any kind whatsoever, the expression of infinity, we may be certain that the workman has gone to nature for it; while, on the other hand, the moment we see repetition, or want of infinity, we may be certain that the workman has not gone to nature for it.

For instance, in the picture of Salvator before noticed, No. 220 in the Dulwich Gallery, as we see at once that the two [§ 23. Instances of the total want of it in the works of Salvator.]masses of cloud absolutely repeat each other in every one of their forms, and that each is composed of about twelve white sweeps of the brush, all forming the same curve, and all of the same length; and as we can count these, and measure their common diameter, and by stating the same to anybody else, convey to him a full and perfect idea and knowledge of that sky in all its parts and proportions,—as we can do this, we may be absolutely certain, without reference to the real sky, or to any other part of nature, without even knowing what the white things were intended for, we may be certain that they cannot possibly resemble anything; that whatever they were meant for, they can be nothing but a violent contradiction of all nature's principles and forms. When, on the other hand, we take up such a sky as that of Turner's Rouen, seen from St. Catherine's Hill, in the Rivers of [§ 24. And of the universal presence of it in those of Turner. The conclusions which may be arrived at from it.]France, and find, in the first place, that he has given us a distance over the hills in the horizon, into which, when we are tired of penetrating, we must turn and come back again, there being not the remotest chance of getting to the end of it; and when we see that from this measureless distance up to the zenith, the whole sky is one ocean of alternate waves of cloud and light, so blended together that the eye cannot rest on any one without being guided to the next, and so to a hundred more, till it is lost over and over again in every wreath—that if it divides the sky into quarters of inches, and tries to count or comprehend the component parts of any single one of those divisions, it is still as utterly defied and defeated by the part as by the whole—that there is not one line out of the millions there which repeats another, not one which is unconnected with another, not one which does not in itself convey histories of distance and space, and suggest new and changeful form; then we may be all but certain, though these forms are too mysterious and too delicate for us to analyze—though all is so crowded and so connected that it is impossible to test any single part by particular laws—yet without any such tests, we may be sure that this infinity can only be based on truth—that it must be nature, because man could not have originated it, and that every form must be faithful, because none is like another. And therefore it is that I insist so constantly on this great quality of landscape painting, as it appears in Turner; because it is not merely a constant and most important truth in itself, but it almost amounts to a demonstration of every other truth. And it will be found a far rarer attainment in the works of other [§ 25. The multiplication of objects, or increase of their size, will not give the impression of infinity, but is the resource of novices.]men than is commonly supposed, and the sign, wherever it is really found, of the very highest art. For we are apt to forget that the greatest number is no nearer infinity than the least, if it be definite number; and the vastest bulk is no nearer infinity than the most minute, if it be definite bulk; so that a man may multiply his objects forever and ever, and be no nearer infinity than he had reached with one, if he do not vary them and confuse them; and a man may reach infinity in every touch and line, and part, and unit, if in these he be truthfully various and obscure. And we shall find, the more we examine the works of the old masters, that always, and in all parts, they are totally wanting in every feeling of infinity, and therefore in all truth: and even in the works of the moderns, though the aim is far more just, we shall frequently perceive an erroneous choice of means, and a substitution of mere number or bulk for real infinity.
