It would be easy to accumulate examples from other Artists who differ in the economy of line not only from these but from each other; as Raffaelle, Michael Angelo, Correggio, Titian, Poussin,--in a word, every painter deserving the name of master: for lines here may be called the tracks of thought, in which we follow the author's mind through his imaginary creations. They hold, indeed, the same relation to Painting that versification does to Poetry, an element of style; for what is meant by a line in Painting is analogous to that which in the sister art distinguishes the abrupt gait of Crabbe from the sauntering walk of Cowley, and the "long, majestic march" of Dryden from the surging sweep of Milton.
Of Continuity little needs be said, since its uses are implied in the explanation of Line; indeed, all that can be added will be expressed in its essential relation to a whole, in which alone it differs from a mere line. For, though a line (as just explained) supposes a continuous course, yet a line, per se, does not necessarily imply any relation to other lines. It will still be a line, though standing alone; but the principle of continuity may be called the unifying spirit of every line. It is therefore that we have distinguished it as a separate principle.
In fact, if we judge from feeling, the only true test, it is no paradox to say that the excess of variety must inevitably end in monotony; for, as soon as the sense of fatigue begins, every new variety but adds to the pain, till the succeeding impressions are at last resolved into continuous pain. But, supposing a limit to variety, where the mind may be pleasurably excited, the very sense of pleasure, when it reaches the extreme point, will create the desire of renewing it, and naturally carry it back to the point of starting; thus superinducing, with the renewed enjoyment, the fulness of pleasure, in the sense of a whole.
It is by this summing up, as it were, of the memory, through recurrence, not that we perceive,--which is instantaneous,--but that we enjoy any thing as a whole. If we have not observed it in others, some of us, perhaps, may remember it in ourselves, when we have stood before some fine picture, though with a sense of pleasure, yet for many minutes in a manner abstracted,--silently passing through all its harmonious transitions without the movement of a muscle, and hardly conscious of action, till we have suddenly found ourselves returning on our steps. Then it was,--as if we had no eyes till then,--that the magic Whole poured in upon us, and vouched for its truth in an outbreak of rapture.
The fourth and last division of our subject is the Harmony of Parts; or the essential agreement of one part with another, and of each with the whole. In addition to our first general definition, we may further observe, that by a Whole in Painting is signified the complete expression, by means of form, color, light, and shadow, of one thought, or series of thoughts, having for their end some particular truth, or sentiment, or action, or mood of mind. We say thought, because no images, however put together, can ever be separated by the mind from other and extraneous images, so as to comprise a positive whole, unless they be limited by some intellectual boundary. A picture wanting this may have fine parts, but is not a Composition, which implies parts united to each other, and also suited to some specific purpose, otherwise they cannot be known as united. Since Harmony, therefore, cannot be conceived of without reference to a whole, so neither can a whole be imagined without fitness of parts. To give this fitness, then, is the ultimate task and test of genius: it is, in fact, calling form and life out of what before was but a chaos of materials, and making them the subject and exponents of the will. As the master-principle, also, it is the disposer, regulator, and modifier of shape, line, and quantity, adding, diminishing, changing, shaping, till it becomes clear and intelligible, and it finally manifests itself in pleasurable identity with the harmony within us.
To reduce the operation of this principle to precise rules is, perhaps, without the province of human power: we might else expect to see poets and painters made by recipe. As in many other operations of the mind, we must here be content to note a few of the more tangible facts, if we may be allowed the phrase, which have occasionally been gathered by observation during the process. The first fact presented is, that equal quantities, when coming together, produce monotony, and, if at all admissible, are only so when absolutely needed, at a proper distance, to echo back or recall the theme, which would otherwise be lost in the excess of variety. We speak of quantity here as of a mass, not of the minutiae; for the essential components of a part may often be equal quantities, (as in a piece of architecture, of armour, &c.,) which are analogous to poetic feet, for instance, a spondee. The same effect we find from parallel lines and repetition of shapes. Hence we obtain the law of a limited variety. The next is, that the quantities must be so disposed as to balance each other; otherwise, if all or too many of the larger be on one side, they will endanger the imaginary circle, or other figure, by which every composition is supposed to be bounded, making it appear "lop-sided," or to be falling either in upon the smaller quantities, or out of the picture: from which we infer the necessity of balance. If, without others to counteract and restrain them, the parts converge, the eye, being forced to the centre, becomes stationary; in like manner, if all diverge, it is forced to fly off in tangents: as if the great laws of Attraction and Repulsion were here also essential, and illustrated in miniature. If we add to these Breadth, I believe we shall have enumerated all the leading phenomena of Harmony, which experience has enabled us to establish as rules. By breadth is meant such a massing of the quantities, whether by color, light, or shadow, as shall enable the eye to pass without obstruction, and by easy transitions, from one to another, so that it shall appear to take in the whole at a glance. This may be likened to both the exordium and peroration of a discourse, including as well the last as the first general idea. It is, in other words, a simple, connected, and concise exposition and summary of what the artist intends.
We have thus endeavoured to arrange and to give a logical permanency to the several principles of Composition. It is not to be supposed, however, that in these we have every principle that might be named; but they are all, as we conceive, that are of universal application. Of other minor, or rather personal ones, since they pertain to the individual, the number can only be limited by the variety of the human intellect, to which these may be considered as so many simple elementary guides; not to create genius, but to enable it to understand itself, and by a distinct knowledge of its own operations to correct its mistakes,--in a word, to establish the landmarks between the flats of commonplace and the barrens of extravagance. And, though the personal or individual principles referred to may not with propriety be cited as examples in a general treatise like the present, they are not only not to be overlooked, but are to be regarded by the student as legitimate objects of study. To the truism, that we can only judge of other minds by a knowledge of our own, we may add its converse as especially true. In that mysterious tract of the intellect, which we call the Imagination, there would seem to lie hid thousands of unknown forms, of which we are often for years unconscious, until they start up awakened by the footsteps of a stranger. Hence it is that the greatest geniuses, as presenting a wider field for excitement, are generally found to be the widest likers; not so much from affinity, or because they possess the precise kinds of excellence which they admire, but often from the differences which these very excellences in others, as the exciting cause, awaken in themselves. Such men may be said to be endowed with a double vision, an inward and an outward; the inward seeing not unfrequently the reverse of what is seen by the outward. It was this which caused Annibal Caracci to remark, on seeing for the first time a picture by Caravaggio, that he thought a style totally opposite might be made very captivating; and the hint, it is said, sunk deep into and was not lost on Guido, who soon after realized what his master had thus imagined. Perhaps no one ever caught more from others than Raffaelle. I do not allude to his "borrowing," so ingeniously, not soundly, defended by Sir Joshua, but rather to his excitability, (if I may here apply a modern term,)--that inflammable temperament, which took fire, as it were, from the very friction of the atmosphere. For there was scarce an excellence, within his knowledge, of his predecessors or contemporaries, which did not in a greater or less degree contribute to the developement of his powers; not as presenting models of imitation, but as shedding new light on his own mind, and opening to view its hidden treasures. Such to him were the forms of the Antique, of Leonardo da Vinci, and of Michael Angelo, and the breadth and color of Fra Bartolomeo,--lights that first made him acquainted with himself, not lights that he followed; for he was a follower of none. To how many others he was indebted for his impulses cannot now be known; but the new impetus he was known to have received from every new excellence has led many to believe, that, had he lived to see the works of Titian, he would have added to his grace, character, and form, and with equal originality, the splendor of color. "The design of Michael Angelo and the color of Titian," was the inscription of Tintoretto over the door of his painting-room. Whether he intended to designate these two artists as his future models matters not; but that he did not follow them is evidenced in his works. Nor, indeed, could he: the temptation to follow, which his youthful admiration had excited, was met by an interdiction not easily withstood,--the decree of his own genius. And yet the decree had probably never been heard but for these very masters. Their presence stirred him; and, when he thought of serving, his teeming mind poured out its abundance, making him a master to future generations. To the forms of Michael Angelo he was certainly indebted for the elevation of his own; there, however, the inspiration ended. With Titian he was nearly allied in genius; yet he thought rather with than after him,--at times even beyond him. Titian, indeed, may be said to have first opened his eyes to the mysteries of nature; but they were no sooner opened, than he rushed into them with a rapidity and daring unwont to the more cautious spirit of his master; and, though irregular, eccentric, and often inferior, yet sometimes he made his way to poetical regions, of whose celestial hues even Titian himself had never dreamt.
We might go on thus with every great name in Art. But these examples are enough to show how much even the most original minds, not only may, but must, owe to others; for the social law of our nature applies no less to the intellect than to the affections. When applied to genius, it may be called the social inspiration, the simple statement of which seems to us of itself a solution of the oft-repeated question, "Why is it that genius always appears in clusters?" To Nature, indeed, we must all at last recur, as to the only true and permanent foundation of real excellence. But Nature is open to all men alike, in her beauty, her majesty, her grandeur, and her sublimity. Yet who will assert that all men see, or, if they see, are impressed by these her attributes alike? Nay, so great is the difference, that one might almost suppose them inhabitants of different worlds. Of Claude, for instance, it is hardly a metaphor to say that he lived in two worlds during his natural life; for Claude the pastry-cook could never have seen the same world that was made visible to Claude the painter. It was human sympathy, acting through human works, that gave birth to his intellect at the age of forty. There is something, perhaps, ludicrous in the thought of an infant of forty. Yet the fact is a solemn one, that thousands die whose minds have never been born.
We could not, perhaps, instance a stronger confutation of the vulgar error which opposes learning to genius, than the simple history of this remarkable man. In all that respects the mind, he was literally a child, till accident or necessity carried him to Rome; for, when the office of color-grinder, added to that of cook, by awakening his curiosity, first excited a love for the Art, his progress through its rudiments seems to have been scarcely less slow and painful than that of a child through the horrors of the alphabet. It was the struggle of one who was learning to think; but, the rudiments being mastered, he found himself suddenly possessed, not as yet of thought, but of new forms of language; then came thoughts, pouring from his mind, and filling them as moulds, without which they had never, perhaps, had either shape or consciousness.
Now what was this new language but the product of other minds,--of successive minds, amending, enlarging, elaborating, through successive ages, till, fitted to all its wants, it became true to the Ideal, and the vernacular tongue of genius through all time? The first inventor of verse was but the prophetic herald of Homer, Shakspeare, and Milton. And what was Rome then but the great University of Art, where all this accumulated learning was treasured?
