On the Old Road Volume I Part 7

118. We are grieved to interrupt our reader's voyage among the constellations; but the next page crystallizes us again like ants in amber, or worse, in gum-sandarach. It appears, from conclusive and abundant evidence, that the greater cheapness of sandarach, and its easier solubility in oil rendered it the usual subst.i.tute for amber, and that the word Vernice, when it occurs alone, is the common synonym for dry sandarach resin. This, dissolved by heat in linseed oil, three parts oil to one of resin, was the Vernice liquida of the Italians, sold in Cennini's time ready prepared, and the customary varnish of tempera pictures. Concrete turpentine ("oyle of fir-tree," "Pece Greca,"

"Pegola"), previously prepared over a slow fire until it ceased to swell, was added to a.s.sist the liquefaction of the sandarach, first in Venice, where the material could easily be procured, and afterwards in Florence. The varnish so prepared, especially when it was long boiled to render it more drying, was of a dark color, materially affecting the tints over which it was pa.s.sed.[15]

"It is not impossible that the lighter style of coloring introduced by Giotto may have been intended by him to counteract the effects of this varnish, the appearance of which in the Greek pictures he could not fail to observe. Another peculiarity in the works of the painters of the time referred to, particularly those of the Florentine and Sienese schools, is the greenish tone of their coloring in the flesh; produced by the mode in which they often prepared their works, viz. by a green under-painting. The appearance was neutralized by the red sandarac varnish, and pictures executed in the manner described must have looked better before it was removed."--_Ib._ p. 252.

Farther on, this remark is thus followed out:--

"The paleness or freshness of the tempera may have been sometimes calculated for this brown glazing (for such it was in effect), and when this was the case, the picture was, strictly speaking, unfinished without its varnish. It is, therefore, quite conceivable that a painter, averse to mere mechanical operations, would, in his final process, still have an eye to the harmony of his work, and, seeing that the tint of his varnish was more or less adapted to display the hues over which it was spread, would vary that tint, so as to heighten the effect of the picture. The practice of tingeing varnishes was not even new, as the example given by Carda.n.u.s proves. The next step to this would be to treat the tempera picture still more as a preparation, and to calculate still further on the varnish, by modifying and adapting its color to a greater extent. A work so completed must have nearly approached the appearance of an oil picture. This was perhaps the moment when the new method opened itself to the mind of Hubert Van Eyck.... The next change necessarily consisted in using opaque as well as transparent colors; the former being applied over the light, the latter over the darker, portions of the picture; while the work in tempera was now reduced to a light chiaroscuro preparation.... It was now that the hue of the original varnish became an objection; for, as a medium, it required to be itself colorless."--_Ib._ pp. 271-273.

119. Our author has perhaps somewhat embarra.s.sed this part of the argument, by giving too much importance to the conjectural adaptation of the tints of the tempera picture to the brown varnish, and too little to the bold transition from transparent to opaque color on the lights. Up to this time, we must remember, the entire drawing of the flesh had been in tempera; the varnish, however richly tinted, however delicately adjusted to the tints beneath, was still broadly applied over the whole surface, the design being seen through the transparent glaze. But the mixture of opaque color at once implies that portions of the design itself were executed with the varnish for a vehicle, and therefore that the varnish had been entirely changed both in color and consistence. If, as above stated, the improvement in the varnish had been made only after it had been mixed with opaque color, it does not appear why the idea of so mixing it should have presented itself to Van Eyck more than to any other painter of the day, and Vasari's story of the split panel becomes nugatory. But we apprehend, from a previous pa.s.sage (p. 258), that Mr. Eastlake would not have us so interpret him. We rather suppose that we are expressing his real opinion in stating our own, that Van Eyck, seeking for a varnish which would dry in the shade, first perfected the methods of dissolving amber or copal in oil, then sought for and added a good dryer, and thus obtained a varnish which, having been subjected to no long process of boiling, was nearly colorless; that in using this new varnish over tempera works he might cautiously and gradually mix it with the opaque color, whose purity he now found unaffected, by the transparent vehicle; and, finally, as the thickness of the varnish in its less perfect state was an obstacle to precision of execution, increase the proportion of its oil to the amber, or add a diluent, as occasion required.

120. Such, at all events, in the sum, whatever might be the order or occasion of discovery, were Van Eyck's improvements in the vehicle of color, and to these, applied by singular ingenuity and affection to the imitation of nature, with a fidelity hitherto unattempted, Mr. Eastlake attributes the influence which his works obtained over his contemporaries:--

"If we ask in what the chief novelty of his practice consisted, we shall at once recognize it in an amount of general excellence before unknown.

At all times, from Van Eyck's day to the present, whenever nature has been surprisingly well imitated in pictures, the first and last question with the ignorant has been--What materials did the artist use? The superior mechanical secret is always supposed to be in the hands of the greatest genius; and an early example of sudden perfection in art, like the fame of the heroes of antiquity, was likely to monopolize and represent the claims of many."--_Ib._ p. 266.

This is all true; that Van Eyck saw nature more truly than his predecessors is certain; but it is disputable whether this rendering of nature recommended his works to the imitation of the Italians. On the contrary, Mr. Eastlake himself observes in another place (p. 220), that the character of delicate imitation common to the Flemish pictures militated _against_ the acceptance of their method:--

"The specimens of Van Eyck, Hugo van der Goes, Memling, and others, which the Florentines had seen, may have appeared, in the eyes of some severe judges (for example, those who daily studied the frescoes of Masaccio), to indicate a certain connection between oil painting and minuteness, if not always of size, yet of style. The method, by its very finish and the possible completeness of its gradations, must have seemed well calculated to exhibit numerous objects on a small scale. That this was really the impression produced, at a later period, on one who represented the highest style of design, has been lately proved by means of an interesting doc.u.ment, in which the opinions of Michael Angelo on the character of Flemish pictures are recorded by a contemporary artist."[16]

121. It was not, we apprehend, the resemblance to nature, but the abstract power of color, which inflamed with admiration and jealousy the artists of Italy; it was not the delicate touch nor the precise verity of Van Eyck, but the "vivacita de' colori" (says Vasari) which at the first glance induced Antonello da Messina to "put aside every other avocation and thought, and at once set out for Flanders," a.s.siduously to cultivate the friendship of _Giovanni_, presenting to him many drawings and other things, until _Giovanni_, finding himself already old, was content that Antonello should see the method of his coloring in oil, nor then to quit Flanders until he had "thoroughly learned that _process_."

It was this _process_, separate, mysterious, and admirable, whose communication the Venetian, Domenico, thought the most acceptable kindness which could repay his hospitality; and whose solitary possession Castagno thought cheaply purchased by the guilt of the betrayer and murderer; it was in this process, the deduction of watchful intelligence, not by fortuitous discovery, that the first impulse was given to European art. Many a plank had yawned in the sun before Van Eyck's; but he alone saw through the rent, as through an opening portal, the lofty perspective of triumph widening its rapid wedge;--many a spot of opaque color had clouded the transparent amber of earlier times; but the little cloud that rose over Van Eyck's horizon was "like unto a man's hand."

What this process was, and how far it differed from preceding practice, has hardly, perhaps, been p.r.o.nounced by Mr. Eastlake with sufficient distinctness. One or two conclusions which he has not marked are, we think, deducible from his evidence, In one point, and that not an unimportant one, we believe that many careful students of coloring will be disposed to differ with him: our own intermediate opinion we will therefore venture to state, though with all diffidence.

122. We must not, however, pa.s.s entirely without notice the two chapters on the preparation of oils, and on the oleo-resinous vehicles, though to the general reader the recipes contained in them are of little interest; and in the absence of all expression of opinion on the part of Mr.

Eastlake as to their comparative excellence, even to the artist, their immediate utility appears somewhat doubtful. One circ.u.mstance, however, is remarkable in all, the care taken by the great painters, without exception, to avoid the yellowing of their oil. Perfect and stable clearness is the ultimate aim of all the processes described (many of them troublesome and tedious in the extreme): and the effect of the altered oil is of course most dreaded on pale and cold colors. Thus Philippe Nunez tells us how to purify linseed oil "for white and blues;"

and Pacheco, "el de linaza no me quele mal: aunque ai quien diga que no a de ver el Azul ni el Blanco este Azeite."[17] De Mayerne recommends poppy oil "for painting white, blue, and similar colors, so that they shall not yellow;" and in another place, "for air-tints and blue;"--while the inclination to green is noticed as an imperfection in hempseed oil: so Vasari--speaking of linseed-oil in contemporary practice--"benche il noce e meglio, perche ingialla meno." The Italians generally mixed an essential oil with their delicate tints, including flesh tints (p. 431). Extraordinary methods were used by the Flemish painters to protect their blues; they were sometimes painted with size, and varnished; sometimes strewed in powder on fresh white-lead (p.

456). Leonardo gives a careful recipe for preventing the change of color in nut oil, supposing it to be owing to neglect in removing the skin of the nut. His words, given at p. 321, are incorrectly translated: "una certa bucciolina," is not a husk or rind--but "a thin skin," meaning the white membranous covering of the nut itself, of which it is almost impossible to detach all the inner laminae. This, "che tiene della natura del mallo," Leonardo supposes to give the expressed oil its property of forming a _skin_ at the surface.

123. We think these pa.s.sages interesting, because they are entirely opposed to the modern ideas of the desirableness of yellow lights and green blues, which have been introduced chiefly by the study of altered pictures. The anxiety of Rubens, expressed in various letters, quoted at p. 516, lest any of his whites should have become yellow, and his request that his pictures might be exposed to the sun to remedy the defect, if it occurred, are conclusive on this subject, as far as regards the feeling of the Flemish painters: we shall presently see that the _coolness_ of their light was an essential part of their scheme of color.

The testing of the various processes given in these two chapters must be a matter of time: many of them have been superseded by recent discoveries. Copal varnish is in modern practice no inefficient subst.i.tute for amber, and we believe that most artists will agree with us in thinking that the vehicles now in use are sufficient for all purposes, if used rightly. We shall, therefore, proceed in the first place to give a rapid sketch of the entire process of the Flemish school as it is stated by Mr. Eastlake in the 11th chapter, and then examine the several steps of it one by one, with the view at once of marking what seems disputable, and of deducing from what is certain some considerations respecting the consequences of its adoption in subsequent art.

124. The ground was with all the early masters pure _white_, plaster of Paris, or washed chalk with size; a preparation which has been employed without change from remote antiquity--witness the Egyptian mummy-cases.

Such a ground, becoming brittle with age, is evidently unsafe on canvas, unless exceedingly thin; and even on panel is liable to crack and detach itself, unless it be carefully guarded against damp. The precautions of Van Eyck against this danger, as well as against the warping of his panel, are remarkable instances of his regard to points apparently trivial:--

"In large altar-pieces, necessarily composed of many pieces, it may be often remarked that each separate plank has become slightly convex in front: this is particularly observable in the picture of the Transfiguration by Raphael. The heat of candles on altars is supposed to have been the cause of this not uncommon defect; but heat, if considerable, would rather produce the contrary appearance. It would seem that the layer of paint, with its substratum, slightly operates to prevent the wood from contracting or becoming concave on that side; it might therefore be concluded that a similar protection at the back, by equalizing the conditions, would tend to keep the wood flat. The oak panel on which the picture by Van Eyck in the National Gallery is painted is protected at the back by a composition of gesso, size, and tow, over which a coat of black oil-paint was pa.s.sed. This, whether added when the picture was executed or subsequently, has tended to preserve the wood (which is not at all worm-eaten), and perhaps to prevent its warping."--_Ib._ pp. 373, 374.

On the white ground, sc.r.a.ped, when it was perfectly dry, till it was "as white as milk and as smooth as ivory" (Cennini), the outline of the picture was drawn, and its light and shade expressed, usually with the pen, with all possible care; and over this outline a coating of size was applied in order to render the gesso ground _non_-absorbent. The establishment of this fact is of the greatest importance, for the whole question of the true function and use of the gesso ground hangs upon it.

That use has been supposed by all previous writers on the technical processes of painting to be, by absorbing the oil, to remove in some degree the cause of yellowness in the colors. Had this been so, the ground itself would have lost its brilliancy, and it would have followed that a dark ground, equally absorbent, would have answered the purpose as well. But the evidence adduced by Mr. Eastlake on this subject is conclusive:--

"Pictures are sometimes transferred from panel to cloth. The front being secured by smooth paper or linen, the picture is laid on its face, and the wood is gradually planed and sc.r.a.ped away. At last the ground appears; first, the 'gesso grosso,' then, next the painted surface, the 'gesso sottile.' On sc.r.a.ping this it is found that it is whitest immediately next the colors; for on the inner side it may sometimes have received slight stains from the wood, if the latter was not first sized. When a picture which happens to be much cracked has been oiled or varnished, the fluid will sometimes penetrate through the cracks into the ground, which in such parts had become accessible. In that case the white ground is stained in lines only, corresponding in their direction with the cracks of the picture. This last circ.u.mstance also proves that the ground was not sufficiently hard in itself to prevent the absorption of oil. Accordingly, it required to be rendered non-absorbent by a coating of size; and this was pa.s.sed _over_ the outline, before the oil-priming was applied."--_Ib._ pp. 383, 384.

The perfect whiteness of the ground being thus secured, a transparent warm oil-priming, in early practice flesh-colored, was usually pa.s.sed over the entire picture. This custom, says Mr. Eastlake, appears to have been "a remnant of the old habit of covering tempera pictures with a warm varnish, and was sometimes omitted." When used it was permitted to dry thoroughly, and over it the shadows were painted in with a rich transparent brown, mixed with a somewhat thick oleo-resinous vehicle; the lighter colors were then added with a thinner vehicle, taking care not to disturb the transparency of the shadows by the unnecessary mixture of opaque pigments, and leaving the ground bearing bright _through the thin lights_. (?) As the art advanced, the lights were more and more loaded, and afterwards glazed, the shadows being still left in untouched transparency. This is the method of Rubens. The later Italian colorists appear to have laid opaque local color without fear even into the shadows, and to have recovered transparency by ultimate glazing.

125. Such are the princ.i.p.al heads of the method of the early Flemish masters, as stated by Mr. Eastlake. We have marked as questionable the influence of the ground in supporting the lights: our reasons for doing so we will give, after we have stated what we suppose to be the advantages or disadvantages of the process in its earlier stages, guiding ourselves as far as possible by the pa.s.sages in which any expression occurs of Mr. Eastlake's opinion.

The reader cannot but see that the _eminent_ character of the whole system is its predeterminateness. From first to last its success depended on the decision and clearness of each successive step. The drawing and light and shade were secured without any interference of color; but when over these the oil-priming was once laid, the design could neither be altered nor, if lost, recovered; a color laid too opaquely in the shadow destroyed the inner organization of the picture, and remained an irremediable blemish; and it was necessary, in laying color even on the lights, to follow the guidance of the drawing beneath with a caution and precision which rendered anything like freedom of handling, in the modern sense, totally impossible. Every quality which depends on rapidity, accident, or audacity was interdicted; no affectation of ease was suffered to disturb the humility of patient exertion. Let our readers consider in what temper such a work must be undertaken and carried through--a work in which error was irremediable, change impossible--which demanded the drudgery of a student, while it involved the deliberation of a master--in which the patience of a mechanic was to be united with the foresight of a magician--in which no license could be indulged either to fitfulness of temper or felicity of invention--in which haste was forbidden, yet languor fatal, and consistency of conception no less inc.u.mbent than continuity of toil. Let them reflect what kind of men must have been called up and trained by work such as this, and then compare the tones of mind which are likely to be produced by our present practice,--a practice in which alteration is admitted to any extent in any stage--in which neither foundation is laid nor end foreseen--in which all is dared and nothing resolved, everything periled, nothing provided for--in which men play the sycophant in the courts of their humors, and hunt wisps in the marshes of their wits--a practice which invokes accident, evades law, discredits application, despises system, and sets forth with chief exultation, contingent beauty, and extempore invention.

126. But it is not only the fixed nature of the successive steps which influenced the character of these early painters. A peculiar _direction_ was given to their efforts by the close attention to drawing which, as Mr. Eastlake has especially noticed, was involved in the preparation of the design on the white ground. That design was secured with a care and finish which in many instances might seem altogether supererogatory.[18]

The preparation by John Bellini in the Florentine gallery is completed with exhaustless diligence into even the portions farthest removed from the light, where the thick brown of the shadows must necessarily have afterwards concealed the greater part of the work. It was the discipline undergone in producing this preparation which fixed the character of the school. The most important part of the picture was executed not with the brush, but with the point, and the refinements attainable by this instrument dictated the treatment of their subject. Hence the transition to etching and engraving, and the intense love of minute detail, accompanied by an imaginative communication of dignity and power to the smallest forms, in Albert Durer and others. But this attention to minutiae was not the only result; the disposition of light and shade was also affected by the method. Shade was not to be had at small cost; its ma.s.ses could not be dashed on in impetuous generalization, fields for the future recovery of light. They were measured out and wrought to their depths only by expenditure of toil and time; and, as future grounds for color, they were necessarily restricted to the _natural_ shadow of every object, white being left for high lights of whatever hue. In consequence, the character of pervading daylight, almost inevitably produced in the preparation, was afterwards a.s.sumed as a standard in the painting. Effectism, accidental shadows, all obvious and vulgar artistical treatment, were excluded, or introduced only as the lights became more loaded, and were consequently imposed with more facility on the dark ground. Where shade was required in large ma.s.s, it was obtained by introducing an object of locally dark color. The Italian masters who followed Van Eyck's system were in the constant habit of relieving their princ.i.p.al figures by the darkness of some object, foliage, throne, or drapery, introduced behind the head, the open sky being left visible on each side. A green drapery is thus used with great quaintness by John Bellini in the n.o.ble picture of the Brera Gallery; a black screen, with marbled veins, behind the portraits of himself and his brother in the Louvre; a crimson velvet curtain behind the Madonna, in Francia's best picture at Bologna. Where the subject was sacred, and the painter great, this system of pervading light produced pictures of a peculiar and tranquil majesty; where the mind of the painter was irregularly or frivolously imaginative, its temptations to acc.u.mulative detail were too great to be resisted--the spectator was by the German masters overwhelmed with the copious inconsistency of a dream, or compelled to traverse the picture from corner to corner like a museum of curiosities.

127. The chalk or pen preparation being completed, and the oil-priming laid, we have seen that the shadows were laid in with a transparent _brown_ in considerable body. The question next arises--What influence is this part of the process likely to have had upon the _coloring_ of the school? It is to be remembered that the practice was continued to the latest times, and that when the thin light had been long abandoned, and a loaded body of color had taken its place, the brown transparent shadow was still retained, and is retained often to this day, when asphaltum is used as its base, at the risk of the destruction of the picture. The utter loss of many of Reynolds' n.o.blest works has been caused by the lavish use of this pigment. What the pigment actually was in older times is left by Mr. Eastlake undecided:--

"A rich brown, which, whether an earth or mineral alone, or a substance of the kind enriched by the addition of a transparent yellow or orange, is not an unimportant element of the glowing coloring which is remarkable in examples of the school. Such a color, by artificial combinations at least, is easily supplied; and it is repeated, that, in general, the materials now in use are quite as good as those which the Flemish masters had at their command."--_Ib._ p. 488.

At p. 446 it is also a.s.serted that the peculiar glow of the brown of Rubens is hardly to be accounted for by any accidental variety in the Ca.s.sel earths, but was obtained by the mixture of a transparent yellow.

Evidence, however, exists of asphaltum having been used in Flemish pictures, and with safety, even though prepared in the modern manner:--

"It is not ground" (says De Mayerne), "but a drying oil is prepared with litharge, and the pulverized asphaltum mixed with this oil is placed in a gla.s.s vessel, suspended by a thread [in a water bath]. Thus exposed to the fire it melts like b.u.t.ter; when it begins to boil it is instantly removed. It is an excellent color for shadows, and may be glazed like lake; it lasts well."--_Ib._ p. 463.

128. The great advantage of this primary laying in of the darks in brown was the obtaining an unity of shadow throughout the picture, which rendered variety of hue, where it occurred, an instantly accepted evidence of light. It mattered not how vigorous or how deep in tone the ma.s.ses of local color might be, the eye could not confound them with true shadow; it everywhere distinguished the transparent browns as indicative of gloom, and became acutely sensible of the presence and preciousness of light wherever local tints rose out of their depths. But however superior this method may be to the arbitrary use of polychrome shadows, utterly unrelated to the lights, which has been admitted in modern works; and however beautiful or brilliant its results might be in the hands of colorists as faithful as Van Eyck, or as inventive as Rubens; the principle on which it is based becomes dangerous whenever, in a.s.suming that the ultimate hue of every shadow is brown, it presupposes a peculiar and conventional light. It is true, that so long as the early practice of finishing the under-drawing with the pen was continued, the gray of that preparation might perhaps diminish the force of the upper color, which became in that case little more than a glowing varnish--even thus sometimes verging on too monotonous warmth, as the reader may observe in the head of Dandolo, by John Bellini, in the National Gallery. But when, by later and more impetuous hands, the point tracing was dispensed with, and the picture boldly thrown in with the brown pigment, it became matter of great improbability that the force of such a prevalent tint could afterwards be softened or melted into a pure harmony; the painter's feeling for truth was blunted; brilliancy and richness became his object rather than sincerity or solemnity; with the palled sense of color departed the love of light, and the diffused sunshine of the early schools died away in the narrowed rays of Rembrandt. We think it a deficiency in the work before us that the extreme peril of such a principle, incautiously applied, has not been pointed out, and that the method of Rubens has been so highly extolled for its technical perfection, without the slightest notice of the gross mannerism into which its facile brilliancy too frequently betrayed the mighty master.

129. Yet it remains a question how far, under certain limitations and for certain effects, this system of pure brown shadow may be successfully followed. It is not a little singular that it has already been revived in water-colors by a painter who, in his realization of light and splendor of hue, stands without a rival among living schools--Mr. Hunt; his neutral shadows being, we believe, first thrown in frankly with sepia, the color introduced upon the lights, and the central lights afterwards further raised by body color, and glazed. But in this process the sepia shadows are admitted only on objects whose local colors are warm or neutral; wherever the tint of the illumined portion is delicate or peculiar, a relative hue of shade is at once laid on the white paper; and the correspondence with the Flemish school is in the use of brown as the ultimate representative of deep gloom, and in the careful preservation of its transparency, not in the application of brown universally as the shade of all colors. We apprehend that this practice represents, in another medium, the very best mode of applying the Flemish system; and that when the result proposed is an effect of vivid color under bright cool sunshine, it would be impossible to adopt any more perfect means. But a system which in any stage prescribes the use of a certain pigment, implies the adoption of a constant aim, and becomes, in that degree, conventional. Suppose that the effect desired be neither of sunlight nor of bright color, but of grave color subdued by atmosphere, and we believe that the use of brown for an ultimate shadow would be highly inexpedient. With Van Eyck and with Rubens the aim was always consistent: clear daylight, diffused in the one case, concentrated in the other, was yet the hope, the necessity of both; and any process which admitted the slightest dimness, coldness, or opacity, would have been considered an error in their system by either. Alike, to Rubens, came subjects of tumult or tranquillity, of gayety or terror; the nether, earthly, and upper world were to him animated with the same feeling, lighted by the same sun; he dyed in the same lake of fire the warp of the wedding-garment or of the winding-sheet; swept into the same delirium the recklessness of the sensualist, and rapture of the anchorite; saw in tears only their glittering, and in torture only its flush. To such a painter, regarding every subject in the same temper, and all as mere motives for the display of the power of his art, the Flemish system, improved as it became in his hands, was alike sufficient and habitual. But among the greater colorists of Italy the aim was not always so simple nor the method so determinable. We find Tintoret pa.s.sing like a fire-fly from light to darkness in one oscillation, ranging from the fullest prism of solar color to the coldest grays of twilight, and from the silver tingeing of a morning cloud to the lava fire of a volcano: one moment shutting himself into obscure chambers of imagery, the next plunged into the revolutionless day of heaven, and piercing s.p.a.ce, deeper than the mind can follow or the eye fathom; we find him by turns appalling, pensive, splendid, profound, profuse; and throughout sacrificing every minor quality to the power of his prevalent mood. By such an artist it might, perhaps, be presumed that a different system of color would be adopted in almost every picture, and that if a chiaroscuro ground were independently laid, it would be in a neutral gray, susceptible afterwards of harmony with any tone he might determine upon, and not in the vivid brown which necessitated brilliancy of subsequent effect. We believe, accordingly, that while some of the pieces of this master's richer color, such as the Adam and Eve in the Gallery of Venice, and we suspect also the miracle of St. Mark, may be executed on the pure Flemish system, the greater number of his large compositions will be found based on a gray shadow; and that this gray shadow was independently laid we have more direct proof in the a.s.sertion of Boschini, who received his information from the younger Palma: "Quando haveva stabilita questa importante distribuzione, _abboggiava il quadro tutto di chiaroscuro_;" and we have, therefore, no doubt that Tintoret's well-known reply to the question, "What were the most beautiful colors?" "_Il nero, e il bianco_," is to be received in a perfectly literal sense, beyond and above its evident reference to abstract principle. Its main and most valuable meaning was, of course, that the design and light and shade of a picture were of greater importance than its color; (and this Tintoret felt so thoroughly that there is not one of his works which would seriously lose in power if it were translated into chiaroscuro); but it implied also that Tintoret's idea of a shadowed preparation was in gray, and not in brown.
