Ghiberti was brought up as a goldsmith by his stepfather, and it is said that while a youth he spent much of his leisure in modelling portraits and casting imitations of antique gems and coins for his friends. At the same time he practised painting. We find him employed in decorating a palace at Rimini for Carlo Malatesta, when his stepfather recalled him to Florence, in order that he might compete for the gate of the Baptistery. It is probable that from this early training Ghiberti derived the delicacy of style and smoothness of execution that are reckoned among the chief merits of his work. He also developed a manner more pictorial than sculpturesque, which justifies our calling him a painter in bronze. When Sir Joshua Reynolds remarked, "Ghiberti's landscape and buildings occupied so large a portion of the compartments, that the figures remained but secondary objects,"[[84]] his criticism might fairly have been taxed with some injustice even to the second of the two gates. Yet, though exaggerated in severity, his words convey a truth important for the understanding of this period of Italian art.
The first gate may be cited as the supreme achievement of bronze-casting in the Tuscan prime. In the second, by the introduction of elaborate landscapes and the massing together of figures arranged in multitudes at three and sometimes four distances, Ghiberti overstepped the limits that separate sculpture from painting. Having learned perspective from Brunelleschi, he was eager to apply this new science to his own craft, not discerning that it has no place in noble bas-relief. He therefore abandoned the classical and the early Tuscan tradition, whereby reliefs, whether high or low, are strictly restrained to figures arranged in line or grouped together without accessories. Instead of painting frescoes, he set himself to model in bronze whole compositions that might have been expressed with propriety in colour. The point of Sir Joshua's criticism, therefore, is that Ghiberti's practice of distributing figures on a small scale in spacious landscape framework was at variance with the severity of sculptural treatment. The pernicious effect of his example may be traced in much Florentine work of the mid Renaissance period which passed for supremely clever when it was produced. What the unique genius of Ghiberti made not merely pardonable but even admirable, became under other hands no less repulsive than the transference of pictorial effects to painted glass.[[85]]
That Ghiberti was not a great sculptor of statues is proved by his work at Orsammichele. He was no architect, as we know from his incompetence to do more than impede Brunelleschi in the building of the dome. He came into the world to create a new and inimitable style of hybrid beauty in those gates of Paradise. His susceptibility to the first influences of the classical revival deserves notice here, since it shows to what an extent a devotee of Greek art in the fifteenth century could worship the relics of antiquity without passing over into imitation. When the "Hermaphrodite" was discovered in the vineyard of S. Celso, Ghiberti's admiration found vent in exclamations like the following: "No tongue could describe the learning and art displayed in it, or do justice to its masterly style." Another antique, found near Florence, must, he conjectures, have been hidden out of harm's way by "some gentle spirit in the early days of Christianity." "The touch only," he adds, "can discover its beauties, which escape the sense of sight in any light."[[86]] It would be impossible to express a reverential love of ancient art more tenderly than is done in these sentences. So intense was Ghiberti's passion for the Greeks, that he rejected Christian chronology and reckoned by Olympiads—a system that has thrown obscurity over his otherwise precious notes of Tuscan artists. In spite of this devotion, he never appears to have set himself consciously to reproduce the style of Greek sculpture, or to have set forth Hellenic ideas. He remained unaffectedly natural, and in a true sense Christian. The paganism of the Renaissance is a phrase with no more meaning for him than for that still more delicate Florentine spirit, Luca della Robbia; and if his works are classical, they are so only in Goethe's sense, when he pronounced, "the point is for a work to be thoroughly good, and then it is sure to be classical."
One great advantage of the early days of the Renaissance over the latter was this, that pseudo-paganism and pedantry had not as yet distorted the judgment or misdirected the aims of artists. Contact with the antique world served only to stimulate original endeavour, by leading the student back to the fountain of all excellence in nature, and by exhibiting types of perfection in technical processes. To ape the sculptors of Antinous, or to bring to life again the gods who died with Pan, was not yet longed for. Of the impunity with which a sculptor in that period could submit his genius to the service and the study of ancient art without sacrificing individuality, Donatello furnishes a still more illustrious example than Ghiberti. Early in his youth Donatello journeyed with Brunelleschi to Rome, in order to acquaint himself with the monuments then extant. How thoroughly he comprehended the classic spirit is proved by the bronze patera wrought for his patron Ruberto Martelli, and by the frieze of the triumphant Bacchus.[[87]] Yet the great achievements of his genius were Christian in their sentiment and realistic in their style. The bronze "Magdalen" of the Florentine Baptistery and the bronze "Baptist" of the Duomo at Siena[[88]] are executed with an unrelenting materialism, not alien indeed to the sincerity of classic art, but divergent from antique tradition, inasmuch as the ideas of repentant and prophetic asceticism had no place in Greek mythology.
Donatello, with the uncompromising candour of an artist bent on marking character, felt that he was bound to seize the very pith and kernel of his subject. If a Magdalen were demanded of him, he would not condescend to model a Venus and then place a book and skull upon a rock beside her; nor did he imagine that the bloom and beauty of a laughing Faun were fitting attributes for the preacher of repentance. It remained for later artists, intoxicated with antique loveliness and corroded with worldly scepticism, to reproduce the outward semblance of Greek deities under the pretence of setting forth the myths of Christianity. Such compromise had not occurred to Donatello. The motive of his art was clearly apprehended, his method was sincere; certain phases of profound emotion had to be represented with the physical characteristics proper to them. The result, ugly and painful as it may sometimes be, was really more concordant with the spirit of Greek method than Lionardo's "John" or Correggio's "Magdalen." That is to say, it was straightforward and truthful; whereas the strange caprices of the later Renaissance too often betrayed a double mind, disloyal alike to paganism and to Christianity, in their effort to combine divergent forces. It may still be argued that such conceptions as sorrow for sin and mortification of the flesh, unflinchingly portrayed by haggard gauntness in the saints of Donatello, are unfit for sculpturesque expression.
A more felicitous embodiment of modern feeling was achieved by Donatello in "S. George" and "David." The former is a marble statue placed upon the north wall of Orsammichele; the latter is a bronze, cast for Cosimo de' Medici, and now exhibited in the Bargello.[[89]] Without striving to idealise his models, the sculptor has expressed in both the Christian conception of heroism, fearless in the face of danger, and sustained by faith. The naked beauty of the boy David and the mailed manhood of S. George are raised to a spiritual region by the type of feature and the pose of body selected to interpret their animating impulse. These are no mere portraits of wrestlers, such, as peopled the groves of Altis at Olympia, no ideals of physical strength translated into brass and marble, like the "Hercules" of Naples or the Vatican. The one is a Christian soldier ready to engage Apollyon in battle to the death; the other the boy-hero of a marvellous romance. The body in both is but the shrine of an indwelling soul, the instrument and agent of a faith-directed will; and the crown of their conflict is no wreath of laurel or of parsley. In other words, the value of S. George and David to the sculptor lay not in their strength and youthful beauty—though he has endowed them with these excellent gifts—so much as in their significance for the eternal struggle of the soul with evil. The same power of expressing Christian sentiment in a form of perfect beauty, transcending the Greek type by profounder suggestion of feeling, is illustrated in the well-known low-relief of an angel's head in profile, technically one of Donatello's most masterly productions.[[90]]
It is no part of my present purpose to enumerate the many works of Donatello in marble and bronze; yet some allusion to their number and variety is necessary in order to show how widely his influence was diffused through Italy. In the monuments of Pope John XXIII., of Cardinal Brancacci, and of Bartolommeo Aragazzi, he subordinated his genius to the treatment of sepulchral and biographical subjects according to time-honoured Tuscan usage. They were severally placed in Florence, Naples, and Montepulciano. For the cathedral of Prato he executed bas-reliefs of dancing boys; a similar series, intended for the balustrades of the organ in S. Maria del Fiore, is now preserved in the Bargello museum. The exultation of movement has never been expressed in stone with more fidelity to the strict rules of plastic art. For his friend and patron, Cosimo de' Medici, he cast in bronze the group of "Judith and Holofernes"—a work that illustrates the clumsiness of realistic treatment, and deserves to be remembered chiefly for its strange fortunes. When the Medici fled from Florence in 1494, their palace was sacked; the new republic took possession of Donatello's "Judith," and placed it on a pedestal before the gate of the Palazzo Vecchio, with this inscription, ominous to would-be despots: Exemplum salutis publicæ cives posuere. MCCCCXCV. It now stands near Cellini's "Perseus" under the Loggia de' Lanzi. For the pulpits of S. Lorenzo, Donatello made designs of intricate bronze bas-reliefs, which were afterwards completed by his pupil Bertoldo. These, though better known to travellers, are less excellent than the reliefs in bronze wrought by Donatello's own hand for the church of S. Anthony at Padua.[[91]] To that city he was called in 1451, in order that he might model the equestrian statue of Gattamelata. It still stands on the Piazza, a masterpiece of scientific bronze-founding, the first great portrait of a general on horseback since the days of Rome.[[92]] At Padua, in the hall of the Palazzo della Ragione, is also preserved the wooden horse, which is said to have been constructed by the sculptor for the noble house of Capodilista. These two examples of equestrian modelling marked an epoch in Italian statuary.
When Donato di Nicolo di Betto Bardi, called Donatello because men loved his sweet and cheerful temper, died in 1466 at the age of eighty, the brightest light of Italian sculpture in its most promising period was extinguished. Donatello's influence, felt far and wide through Italy, was of inestimable value in correcting the false direction toward pictorial sculpture which Ghiberti, had he flourished alone at Florence, might have given to the art. His style was always eminently masculine. However tastes may differ about the positive merits of his several works, there can be no doubt that the principles of sincerity, truth to nature, and technical accuracy they illustrate, were all-important in an age that lent itself too readily to the caprices of the fancy and the puerilities of florid taste. To regret that Donatello lacked Ghiberti's exquisite sense of beauty, is tantamount to wishing that two of the greatest artists of the world had made one man between them.
Donatello did not, in the strict sense of the term, found a school.[[93]] Andrea Verocchio, goldsmith, painter, and worker in bronze, was the most distinguished of his pupils. To all the arts he practised, Verocchio applied limited powers, a meagre manner, and a prosaic mind. Yet few men have exercised at a very critical moment a more decided influence. The mere fact that he numbered Lionardo da Vinci, Lorenzo di Credi, and Pietro Perugino among his scholars, proves the esteem of his contemporaries; and when we have observed that the type of face selected by Lionardo and transmitted to his followers, appears also in the pictures of Lorenzo di Credi and is first found in the "David" of Verocchio, we have a right to affirm that the master of these men was an artist of creative genius as well as a careful workman. Florence still points with pride to the "Incredulity of Thomas" on the eastern wall of Orsammichele, to the "Boy and Dolphin" in the court of the Palazzo Vecchio, and to the "David" of this sculptor: but the first is spoiled by heaviness and angularity of drapery; the second, though fanciful and marked by fluttering movement, is but a caprice; the third outdoes the hardest work of Donatello by its realism. Verocchio's "David," a lad of some seventeen years, has the lean, veined arms of a stone-hewer or gold-beater. As a faithful portrait of the first Florentine prentice who came to hand, this statue might have merit but for the awkward cuirass and kilt that partly drape the figure.
