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' noblest 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 asserted that the peculiar glow of the brown of Rubens is hardly to be accounted for by any accidental variety in the Cassel 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 glass vessel, suspended by a thread [in a water bath]. Thus exposed to the fire it melts like butter; 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 masses 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 assuming 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 passing 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 space, 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 assertion 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.
