47. His account of Niccola Pisano, the founder of the first great school of middle age sculpture, is thus introduced:—
"Niccola's peculiar praise is this,—that, in practice at least, if not in theory, he first established the principle that the study of nature, corrected by the ideal of the antique, and animated by the spirit of Christianity, personal and social, can alone lead to excellence in art:—each of the three elements of human nature—Matter, Mind, and Spirit—being thus brought into union and co-operation in the service of God, in due relative harmony and subordination. I cannot over-estimate the importance of this principle; it was on this that, consciously or unconsciously, Niccola himself worked—it has been by following it that Donatello and Ghiberti, Leonardo, Raphael, and Michael Angelo have risen to glory. The Sienese school and the Florentine, minds contemplative and dramatic, are alike beholden to it for whatever success has attended their efforts. Like a treble-stranded rope, it drags after it the triumphal car of Christian Art. But if either of the strands be broken, if either of the three elements be pursued disjointedly from the other two, the result is, in each respective case, grossness, pedantry, or weakness:—the exclusive imitation of Nature produces a Caravaggio, a Rubens, a Rembrandt—that of the Antique, a Pellegrino di Tibaldo and a David; and though there be a native chastity and taste in religion, which restrains those who worship it too abstractedly from Intellect and Sense, from running into such extremes, it cannot at least supply that mechanical apparatus which will enable them to soar:—such devotees must be content to gaze up into heaven, like angels cropt of their wings."—Vol. ii., p. 102-3.
48. This is mere Bolognese eclecticism in other terms, and those terms incorrect. We are amazed to find a writer usually thoughtful, if not accurate, thus indolently adopting the worn-out falsities of our weakest writers on Taste. Does he—can he for an instant suppose that the ruffian Caravaggio, distinguished only by his preference of candlelight and black shadows for the illustration and re-enforcement of villainy, painted nature—mere nature—exclusive nature, more painfully or heartily than John Bellini or Raphael? Does he not see that whatever men imitate must be nature of some kind, material nature or spiritual, lovely or foul, brutal or human, but nature still? Does he himself see in mere, external, copyable nature, no more than Caravaggio saw, or in the Antique no more than has been comprehended by David? The fact is, that all artists are primarily divided into the two great groups of Imitators and Suggesters—their falling into one or other being dependent partly on disposition, and partly on the matter they have to subdue—(thus Perugino imitates line by line with penciled gold, the hair which Nino Pisano can only suggest by a gilded marble mass, both having the will of representation alike). And each of these classes is again divided into the faithful and unfaithful imitators and suggesters; and that is a broad question of blind eye and hard heart, or seeing eye and serious heart, always co-existent; and then the faithful imitators and suggesters—artists proper, are appointed, each with his peculiar gift and affection, over the several orders and classes of things natural, to be by them illumined and set forth.
49. And that is God's doing and distributing; and none is rashly to be thought inferior to another, as if by his own fault; nor any of them stimulated to emulation, and changing places with others, although their allotted tasks be of different dignities, and their granted instruments of different keenness; for in none of them can there be a perfection or balance of all human attributes;—the great colorist becomes gradually insensible to the refinements of form which he at first intentionally omitted; the master of line is inevitably dead to many of the delights of color; the study of the true or ideal human form is inconsistent with the love of its most spiritual expressions. To one it is intrusted to record the historical realities of his age; in him the perception of character is subtle, and that of abstract beauty in measure diminished; to another, removed to the desert, or inclosed in the cloister, is given, not the noting of things transient, but the revealing of things eternal. Ghirlandajo and Titian painted men, but could not angels; Duccio and Angelico painted Saints, but could not senators. One is ordered to copy material form lovingly and slowly—his the fine finger and patient will: to another are sent visions and dreams upon the bed—his the hand fearful and swift, and impulse of passion irregular and wild. We may have occasion further to insist upon this great principle of the incommunicableness and singleness of all the highest powers; but we assert it here especially, in opposition to the idea, already so fatal to art, that either the aim of the antique may take place together with the purposes, or its traditions become elevatory of the power, of Christian art; or that the glories of Giotto and the Sienese are in any wise traceable through Niccola Pisano to the venerable relics of the Campo Santo.
50. Lord Lindsay's statement, as far as it regards Niccola himself, is true.
"His improvement in Sculpture is attributable, in the first instance, to the study of an ancient sarcophagus, brought from Greece by the ships of Pisa in the eleventh century, and which, after having stood beside the door of the Duomo for many centuries as the tomb of the Countess Beatrice, mother of the celebrated Matilda, has been recently removed to the Campo Santo. The front is sculptured in bas-relief, in two compartments, the one representing Hippolytus rejecting the suit of Phædra, the other his departure for the chase:—such at least is the most plausible interpretation. The sculpture, if not super-excellent, is substantially good, and the benefit derived from it by Niccola is perceptible on the slightest examination of his works. Other remains of antiquity are preserved at Pisa, which he may have also studied, but this was the classic well from which he drew those waters which became wine when poured into the hallowing chalice of Christianity. I need scarcely add that the mere presence of such models would have availed little, had not nature endowed him with the quick eye and the intuitive apprehension of genius, together with a purity of taste which taught him how to select, how to modify and how to reinspire the germs of excellence thus presented to him."—Vol. ii., pp. 104, 105.
51. But whatever characters peculiarly classical were impressed upon Niccola by this study, died out gradually among his scholars; and in Orcagna the Byzantine manner finally triumphed, leading the way to the purely Christian sculpture of the school of Fiesole, in its turn swept away by the returning wave of classicalism. The sculpture of Orcagna, Giotto, and Mino da Fiesole, would have been what it was, if Niccola had been buried in his sarcophagus; and this is sufficiently proved by Giotto's remaining entirely uninfluenced by the educated excellence of Andrea Pisano, while he gradually bent the Pisan down to his own uncompromising simplicity. If, as Lord Lindsay asserts, "Giotto had learned from the works of Niccola the grand principle of Christian art," the sculptures of the Campanile of Florence would not now have stood forth in contrasted awfulness of simplicity, beside those of the south door of the Baptistery.
52. "Andrea's merit was indeed very great; his works, compared with those of Giovanni and Niccola Pisano, exhibit a progress in design, grace, composition and mechanical execution, at first sight unaccountable—a chasm yawns between them, deep and broad, over which the younger artist seems to have leapt at a bound,—the stream that sank into the earth at Pisa emerges a river at Florence. The solution of the mystery lies in the peculiar plasticity of Andrea's genius, and the ascendency acquired over it by Giotto, although a younger man, from the first moment they came into contact. Giotto had learnt from the works of Niccola the grand principle of Christian art, imperfectly apprehended by Giovanni and his other pupils, and by following up which he had in the natural course of things improved upon his prototype. He now repaid to Sculpture, in the person of Andrea, the sum of improvement in which he stood her debtor in that of Niccola:—so far, that is to say, as the treasury of Andrea's mind was capable of taking it in, for it would be an error to suppose that Andrea profited by Giotto in the same independent manner or degree that Giotto profited by Niccola. Andrea's was not a mind of strong individuality; he became completely Giottesque in thought and style, and as Giotto and he continued intimate friends through life, the impression never wore off:—most fortunate, indeed, that it was so, for the welfare of Sculpture in general, and for that of the buildings in decorating which the friends worked in concert.
"Happily, Andrea's most important work, the bronze door of the Baptistery, still exists, and with every prospect of preservation. It is adorned with bas-reliefs from the history of S. John, with allegorical figures of virtues and heads of prophets, all most beautiful,—the historical compositions distinguished
