In the twilight of this new dawn of the love of nature, perhaps the first figure we may descry is Piero di Giovanni Tedesco (1386-1402), who carved the second south door of the Duomo about 1398, where amid so many lovely natural things, the fig leaf and the oak leaf and the vine, you may see the lion and the ox, the dog and the snail, and man too; little fantastic children peeping out from the foliage, or blowing through musical reeds, or playing with a kitten, tiny naked creatures full of life and gladness.
The second door north of the Duomo was carved by Niccolò di Piero d'Arezzo, who was still working more than forty years after Tedesco's death; but his best work, for we pass by his Statue of St. Mark in the chapel of the apex of the Duomo, is the little Annunciation over the niche of the St. Matthew of Or San Michele. In his work on the gate of the Duomo, however, he was assisted by his pupil Nanni di Banco, who, born in the fourteenth century, died in 1420; and in his work, and in that of Jacopo della Quercia, a Sienese, and a much greater man, we see the very dawn itself.
Nanni di Banco, Vasari tells us, was a man who "inherited a competent patrimony, and one by no means of inferior condition." He goes on to say that Nanni was the pupil of Donatello, and though in any technical sense that seems to be untrue, it may well be that he sought Donato's advice whenever he could, for he seems to have practised his art for love of it, and may well have recognised the genius of Donatello, who probably worked beside him. He too worked at Or San Michele, where he carved the St. Philip, the delightful relief under the St. George of Donatello, the Four Saints, which seem to us so full of the remembrance of antiquity, and the S. Eligius with its beautiful drapery, a little stupid still, or sleepy is it, with the mystery of the Middle Age that after all was but just passing away. Something of this sleepiness seems also to have overtaken the St. Luke, that tired figure in the Duomo; and so it is with a real surprise that we come at last upon the best work of Nanni's life, "the first great living composition of the Renaissances," as Burckhardt says, the Madonna della Cintola over Niccolò d'Arezzo's door of the Duomo. Even with all the work of Ghiberti, of Donatello even, to choose from, that relief of Madonna in an almond-shaped glory, stretching out her hands among the cherubim, with a gesture so eager and so moving to St. Thomas, who kneels before her, remains one of the most beautiful works of that age, and one of the loveliest in all Tuscany.
There follows Ciuffagni (1381-1457), that poor sculptor working in his old age amid much that was splendid and strange at Rimini, where Lorenzo Ghiberti (1378-1455) had painted in his youth. For all his genius, Ghiberti, that euphuist, did not influence those who came after him as Donatello did. His work, inspired by the past, by Andrea Pisano, for instance, is full of the lost beauty of the Middle Age, the old secrets of the Gothic manner. His solution of the problem before him, a problem of movement, of character, of life, is to make the relief as purely picturesque as possible; with him sculpture almost passes into painting, using not without charm the perspective of a picture the mere seeming of just that, but losing how profoundly, much of the nobility, the delight of pure form, the genius peculiar to sculpture. As an artist pure and simple, as a master of composition, he may well have no superior, for the fantasy and beauty of his work, its complexity, too, are almost unique, and entirely his own; but in simplicity, and in a certain sense of reality, he is wanting, so that however delightful his work may be, those "gates of Paradise," for instance, that Michelangelo praised, it seems to be complete in itself, to suggest nothing but the wonderful effect one may get by using the means proper to one art for expression in another, as though one were to write a book that should have the effect upon one of an opera, to allow the strange rhythm and sensuous beauty of Tristan and Isolde, for instance, to disengage itself from pages which were full of just musical words.
Ghiberti's gift for composition, as well as his failure to understand, or at least to satisfy the more fundamental needs of his art, may be seen very happily in those two panels now in the Bargello, which he and Brunellesco made in the competition for the gates of the Baptistery. Looking on those two panels, where both artists have carved the Sacrifice of Isaac, you see Ghiberti at his best, the whole interest not divided, as it is in Brunellesco's panel, between the servants and the sacrifice, but concentrated altogether upon that scene which is about to become so tragical. Yet with what energy Brunellesco has conceived an act that in his hands seems really to have happened. How swiftly the angel has seized the hand of Abraham; how splendidly he stands, the old man who is about to kill his only son for the love of God. And then consider the beauty of Isaac, that naked body which in Brunellesco's hands is splendid with life, really living and noble, with a truth and loveliness far in advance of the art of his time. Ghiberti has felt none of the joy of a creation such as this; his Isaac is sleepy, a little surprised and altogether docile; he has not sprung up from his knees as in Brunellesco's panel, but looks up at the angel as though he had never understood that his very life was at stake. Yet it was in those gates which, Brunellesco, as it is said, retiring from the contest, the Opera then gave into his hands, that we shall find the best work of Ghiberti. There it is really the art of Andrea Pisano that he takes as a master, and with so fair an example before him produces as splendid a thing as he ever accomplished, simpler too, and it may be more sincere, though a little lacking in expressiveness and life. All the rest of his work seems to me to be lacking in conviction, to be frankly almost an experiment. His Statue of St. John Baptist, his St. Matthew and St. Stephen, too, at Or San Michele, different though they are, and with six years between each of them, seem alike in this, that they are, while splendid in energy, wanting in purpose, in intention: he never seems sufficiently sure of himself to convince us. His reliquary in bronze containing the ashes of S. Zenobius in the apse of the Duomo, is difficult to see, but it is in the manner of the gates of Paradise. It was not to the disciples of Ghiberti that the future belonged, but to those who have studied with Brunellesco. His crucifix in S. Maria Novella, his Evangelists in the Pazzi Chapel, are among the finest work of that age, full of life and the remembrance of it in their strength and beauty.
It is, however, in the art of a contemporary that the new age came at last to its own—in the work of Donatello. In his youth he had worked for the Duomo and for Or San Michele side by side with Nanni di Banco, who may perhaps pass as his master. Of Donatello's life we know almost nothing If we seek to learn something of him, it must be in his works of which so many remain to us. We know, however, that he was the intimate friend of Brunellesco, and that it was with him he set out for Rome soon after this great and proud man had withdrawn from the contest with Ghiberti for the Baptistery gates. Donatello was to visit Rome again in later life, but on this first journey that he made with Brunellesco for the purposes of study, he must have become acquainted with what was left of antiquity in the Eternal City. It was too soon for that enthusiasm for antiquity, which later overwhelmed Italian art so disastrously, to have arisen. When Donatello returned about a year later to Florence to work for the Opera del Duomo, it is not any classic influence we find in his statues, but rather the study of nature, an extraordinary desire to express not beauty, scarcely ever that, but character. His work is strong, and often splendid, full of energy, movement, and conviction, but save now and then, as in the S. Croce Annunciation, for instance, it is not content with just beauty.
Of his work for the Duomo and the Campanile, I speak elsewhere; it will be sufficient here to note the splendour of the St. John the Divine in the apse of the Duomo, which, as Burckhardt has divined, already suggests the Moses of Michelangelo. The destruction of the unfinished façade has perhaps made it more difficult to identify the figures he carved there, but whether the Poggio of the Duomo, for instance, be Job or no, seems after all to matter very little, since that statue itself, be its subject what it may, remains to us.
In his work at Or San Michele, in the St. Peter, in the St. Mark, so like the St. John the Divine and in the St. George, here in the Bargello, we see his progress, and there in that last figure we find just that decision and simplicity which seem to have been his own, with a certain frankness and beauty of youth which are new in his work.
