The first of these meanings of the word "tone" is liable to be confounded with what is commonly called "aerial perspective." But aerial perspective is the expression of space, by any [§ 3. Difference between tone in its first sense and aerial perspective.]means whatsoever, sharpness of edge, vividness of color, etc., assisted by greater pitch of shadow, and requires only that objects should be detached from each other, by degrees of intensity in proportion to their distance, without requiring that the difference between the farthest and nearest should be in positive quantity the same that nature has put. But what I have called "tone" requires that there should be the same sum of difference, as well as the same division of differences.

Now the finely toned pictures of the old masters are, in this respect, some of the notes of nature played two or three octaves below her key; the dark objects in the middle distance having [§ 4. The pictures of the old masters perfect in relation of middle tints to light.]precisely the same relation to the light of the sky which they have in nature, but the light being necessarily infinitely lowered, and the mass of the shadow deepened in the same degree. I have often been struck, when looking at a camera-obscuro on a dark day, with the exact resemblance the image bore to one of the finest pictures of the old masters; all the foliage coming dark against the sky, and nothing being seen in its mass but here and there the isolated light of a silvery stem or an unusually illumined cluster of leafage.

Now if this could be done consistently, and all the notes of [§ 5. And consequently totally false in relation of middle tints to darkness.]nature given in this way an octave or two down, it would be right and necessary so to do: but be it observed, not only does nature surpass us in power of obtaining light as much as the sun surpasses white paper, but she also infinitely surpasses us in her power of shade. Her deepest shades are void spaces from which no light whatever is reflected to the eye; ours are black surfaces from which, paint as black as we may, a great deal of light is still reflected, and which, placed against one of nature's deep bits of gloom, would tell as distinct light. Here we are then, with white paper for our highest light, and visible illumined surface for our deepest shadow, set to run the gauntlet against nature, with the sun for her light, and vacuity for her gloom. It is evident that she can well afford to throw her material objects dark against the brilliant aerial tone of her sky, and yet give in those objects themselves a thousand intermediate distances and tones before she comes to black, or to anything like it—all the illumined surfaces of her objects being as distinctly and vividly brighter than her nearest and darkest shadows, as the sky is brighter than those illumined surfaces. But if we, against our poor, dull obscurity of yellow paint, instead of sky, insist on having the same relation of shade in material objects, we go down to the bottom of our scale at once; and what in the world are we to do then? Where are all our intermediate distances to come from?—how are we to express the aerial relations among the parts themselves, for instance, of foliage, whose most distant boughs are already almost black?—how are we to come up from this to the foreground, and when we have done so, how are we to express the distinction between its solid parts, already as dark as we can make them, and its vacant hollows, which nature has marked sharp and clear and black, among its lighted surfaces? It cannot but be evident at a glance, that if to any one of the steps from one distance to another, we give the same quantity of difference in pitch of shade which nature does, we must pay for this expenditure of our means by totally missing half a dozen distances, not a whit less important or marked, and so sacrifice a multitude of truths, to obtain one. And this, accordingly was the means by which the old masters obtained their (truth?) of tone. They chose those steps of distance which are the most conspicuous and noticeable—that for instance from sky to foliage, or from clouds to hills—and they gave these their precise pitch of difference in shade with exquisite accuracy of imitation. Their means were then exhausted, and they were obliged to leave their trees flat masses of mere filled-up outline, and to omit the truths of space in every individual part of their picture by the thousand. But this they did not care for; it saved them trouble; they reached their grand end, imitative effect; they thrust home just at the places where the common and careless eye looks for imitation, and they attained the broadest and most faithful appearance of truth of tone which art can exhibit.

But they are prodigals, and foolish prodigals, in art; they lavish their whole means to get one truth, and leave themselves powerless when they should seize a thousand. And is it indeed [§6. General falsehood of such a system.]worthy of being called a truth, when we have a vast history given us to relate, to the fulness of which neither our limits nor our language are adequate, instead of giving all its parts abridged in the order of their importance, to omit or deny the greater part of them, that we may dwell with verbal fidelity on two or three? Nay, the very truth to which the rest are sacrificed is rendered falsehood by their absence, the relation of the tree to the sky is marked as an impossibility by the want of relation of its parts to each other.

Turner starts from the beginning with a totally different principle. He boldly takes pure white (and justly, for it is the sign of the most intense sunbeams) for his highest light, and [§ 7. The principle of Turner in this respect.]lampblack for his deepest shade; and between these he makes every degree of shade indicative of separate degree of distance,[[16]] giving each step of approach, not the exact difference in pitch which it would have in nature, but a difference bearing the same proportion to that which his sum of possible shade bears to the sum of nature's shade; so that an object half way between his horizon and his foreground, will be exactly in half tint of force, and every minute division of intermediate space will have just its proportionate share of the lesser sum, and no more. Hence where the old masters expressed one distance, he expresses a hundred; and where they said furlongs, he says leagues. Which of these modes of procedure be most agreeable with truth, I think I may safely leave the reader to decide for himself. He will see in this very first instance, one proof of what we above asserted, that the deceptive imitation of nature is inconsistent with real truth; for the very means by which the old masters attained the apparent accuracy of tone which is so satisfying to the eye, compelled them to give up all idea of real relations of retirement, and to represent a few successive and marked stages of distance, like the scenes of a theatre, instead of the imperceptible, multitudinous, symmetrical retirement of nature, who is not more careful to separate her nearest bush from her farthest one, than to separate the nearest bough of that bush from the one next to it.

Take for instance, one of the finest landscapes that ancient art has produced—the work of a really great and intellectual mind, the quiet Nicholas Poussin, in our own National Gallery, [§ 8. Comparison of N. Poussin's "Phocion,"]with the traveller washing his feet. The first idea we receive from this picture is, that it is evening, and all the light coming from the horizon. Not so. It is full moon, the light coming steep from the left, as is shown by the shadow of the stick on the right-hand pedestal,—(for if the sun were not very high, that shadow could not lose itself half way down, and if it were not lateral, the shadow would slope, instead of being vertical.) Now, ask yourself, and answer candidly, if those black masses of foliage, in which scarcely any form is seen but the outline, be a true representation of trees under noonday sunlight, sloping from the left, bringing out, as it necessarily would do, their masses into golden green, and marking every leaf and bough with sharp shadow and sparkling light. The only truth in the picture is the exact pitch of relief against the sky of both trees and hills, and to this the organization of the hills, the intricacy of the foliage, and everything indicative either of the nature of the light, or the character of the objects, are unhesitatingly sacrificed. So much falsehood does it cost to obtain two apparent truths of tone. Or take, as a still more glaring instance, No. 260 in the Dulwich Gallery, where the trunks of the trees, even of those farthest off, on the left, are as black as paint can make them, and there is not, and cannot be, the slightest increase of force, or any marking whatsoever of distance by color, or any other means, between them and the foreground.

Compare with these, Turner's treatment of his materials in the Mercury and Argus. He has here his light actually coming from the distance, the sun being nearly in the centre of the [§ 9. With Turner's "Mercury and Argus."]picture, and a violent relief of objects against it would be far more justifiable than in Poussin's case. But this dark relief is used in its full force only with the nearest leaves of the nearest group of foliage overhanging the foreground from the left; and between these and the more distant members of the same group, though only three or four yards separate, distinct aerial perspective and intervening mist and light are shown; while the large tree in the centre, though very dark, as being very near, compared with all the distance, is much diminished in intensity of shade from this nearest group of leaves, and is faint compared with all the foreground. It is true that this tree has not, in consequence, the actual pitch of shade against the sky which it would have in nature; but it has precisely as much as it possibly can have, to leave it the same proportionate relation to the objects near at hand. And it cannot but be evident to the thoughtful reader, that whatever trickery or deception may be the result of a contrary mode of treatment, this is the only scientific or essentially truthful system, and that what it loses in tone it gains in aerial perspective.

Compare again the last vignette in Rogers's Poems, the "Datur Hora Quieti," where everything, even the darkest parts of the trees, is kept pale and full of graduation; even the bridge [§ 10. And with the "Datur Hora Quieti."]where it crosses the descending stream of sunshine, rather lost in the light than relieved against it, until we come up to the foreground, and then the vigorous local black of the plough throws the whole picture into distance and sunshine. I do not know anything in art which can for a moment be set beside this drawing for united intensity of light and repose.

Observe, I am not at present speaking of the beauty or desirableness of the system of the old masters; it may be sublime, and affecting, and ideal, and intellectual, and a great deal more; but all I am concerned with at present is, that it is not true; while Turner's is the closest and most studied approach to truth of which the materials of art admit.

It was not, therefore, with reference to this division of the subject that I admitted inferiority in our great modern master to Claude or Poussin, but with reference to the second and more [§ 11. The second sense of the word "tone."]usual meaning of the word "tone"—the exact relation and fitness of shadow and light, and of the hues of all objects under them; and more especially that precious quality of each color laid on, which makes it appear a quiet color illuminated, not a bright color in shade. But I allow this inferiority only with respect to the paintings of Turner, not to his drawings. I could select from among the [§ 12. Remarkable difference in this respect between the paintings and drawings of Turner.]works named in Chap. VI. of this section, pieces of tone absolutely faultless and perfect, from the coolest grays of wintry dawn to the intense fire of summer noon. And the difference between the prevailing character of these and that of nearly all the paintings, (for the early oil pictures of Turner are far less perfect in tone than the most recent,) it is difficult to account for, but on the supposition that there is something in the material which modern artists in general are incapable of mastering, and which compels Turner himself to think less of tone in oil color, than of other and more important qualities. The total failures of Callcott, whose struggles after tone ended so invariably in shivering winter or brown paint, the misfortune of Landseer with his evening sky in 1842, the frigidity of Stanfield, and the earthiness and opacity which all the magnificent power and admirable science of Etty are unable entirely to conquer, are too fatal and convincing proofs of the want of knowledge of means, rather than of the absence of aim, in modern artists as a body. Yet, [§ 13. Not owing to want of power over the material.]with respect to Turner, however much the want of tone in his early paintings (the Fall of Carthage, for instance, and others painted at a time when he was producing the most exquisite hues of light in water-color) might seem to favor such a supposition, there are passages in his recent works (such, for instance, as the sunlight along the sea, in the Slaver) which directly contradict it, and which prove to us that where he now errs in tone, (as in the Cicero's Villa,) it is less owing to want of power to reach it, than to the pursuit of some different and nobler end. I shall therefore glance at the particular modes in which Turner manages his tone in his present Academy pictures; the early ones must be given up at once. Place a genuine untouched Claude beside the Crossing the Brook, and the difference in value and tenderness of tone will be felt in an instant, and felt the more painfully because all the cool and transparent qualities of Claude would have been here desirable, and in their place, and appear to have been aimed at. The foreground of the Building of Carthage, and the greater part of the architecture of the Fall, are equally heavy and evidently paint, if we compare them with genuine passages of Claude's sunshine. There is a very grand and simple piece of tone in the possession of J. Allnutt, Esq., a sunset behind willows, but even this is wanting in refinement of shadow, and is crude in its extreme distance. Not so with the recent Academy pictures; many of their passages are absolutely faultless; all are refined and marvellous, and with the exception of the Cicero's Villa, we shall find few pictures painted within the last ten years which do not either present us with perfect tone, or with some higher beauty, to which it is necessarily sacrificed. If we glance at the requirements of nature, and her superiority of means to ours, we shall see why and how it is sacrificed.
