Of Donatello as an innovator I have said something above, in considering the Florentine Davids, but he was also the inventor of that low relief in which his school worked, called rilievo stiacciato, of which there are some excellent examples at South Kensington. In Ghiberti's high relief, breaking out often into completely detached figures, he was also a master, as we shall see at S. Lorenzo. But his greatest claim to distinction is his psychological insight allied to perfect mastery of form. His statues were not only the first really great statues since the Greeks, but are still (always leaving Michelangelo on one side as abnormal) the greatest modern examples judged upon a realistic basis. Here in the Bargello, in originals and in casts, he may be adequately appreciated; but to Padua his admirers must certainly go, for the bronze equestrian statue of Gattamelata is there. Donatello was painted by his friend Masaccio at the Carmine, but the fresco has perished. He is to be seen in the Uffizi portico, although that is probably a fancy representation; and again on a tablet in the wall opposite the apse of the Duomo. The only contemporary portrait (and this is very doubtful) is in a picture in the Louvre given to Uccello—a serious, thoughtful, bearded face with steady, observant eyes: one of five heads, the others being Giotto, Manetti, Brunelleschi, and Uccello himself.

Donatello, who never married, but lived for much of his life with his mother and sister, died at a great age, cared for both by Cosimo de' Medici and his son and successor Piero. He was buried with Cosimo in S. Lorenzo. Vasari tells us that he was free, affectionate, and courteous, but of a high spirit and capable of sudden anger, as when he destroyed with a blow a head he had made for a mean patron who objected to its very reasonable price. "He thought," says Vasari, "nothing of money, keeping it in a basket suspended from the ceiling, so that all his workmen and friends took what they wanted without saying anything." He was as careless of dress as great artists have ever been, and of a handsome robe which Cosimo gave him he complained that it spoiled his work. When he was dying his relations affected great concern in the hope of inheriting a farm at Prato, but he told them that he had left it to the peasant who had always toiled there, and he would not alter his will.

The Donatello collection in the Bargello has been made representative by the addition of casts. The originals number ten: there is also a cast of the equestrian statue of Gattemalata at Padua, which is, I suppose, next to Verrocchio's Bartolommeo Colleoni at Venice, the finest equestrian statue that exists; heads from various collections, including M. Dreyfus' in Paris, although Dr. Bode now gives that charming example to Donatello's pupil Desiderio; and various other masterpieces elsewhere. But it is the originals that chiefly interest us, and first of these in bronze is the David, of which I have already spoken, and first of these in marble the S. George. This George is just such a resolute, clean, warlike idealist as one dreams him. He would kill a dragon, it is true; but he would eat and sleep after it and tell the story modestly and not without humour. By a happy chance the marble upon which Donatello worked had light veins running through it just where the head is, with the result that the face seems to possess a radiance of its own. This statue was made for Or San Michele, where it used to stand until 1891, when the present bronze replica that takes its place was made. The spirited marble frieze underneath it at Or San Michele is the original and has been there for centuries. It was this S. George whom Ruskin took as the head and inspiration of his Saint George's Guild.

The David is interesting not only in itself but as being the first isolated statue of modern times. It was made for Cosimo de' Medici, to stand in the courtyard of the Medici palace (now the Riccardi), and until that time, since antiquity, no one had made a statue to stand on a pedestal and be observable from all points. Hitherto modern sculptors had either made reliefs or statues for niches. It was also the first nude statue of modern times; and once again one has the satisfaction of recognizing that the first was the best. At any rate, no later sculptor has made anything more charming than this figure, or more masterly within its limits.

After the S. George and the bronze David, the two most memorable things are the adorable bronze Amorino in its quaint little trousers—or perhaps not Amorino at all, since it is trampling on a snake, which such little sprites did not do—and the coloured terra-cotta bust called Niccolò da Uzzano, so like life as to be after a while disconcerting. The sensitiveness of the mouth can never have been excelled. The other originals include the gaunt John the Baptist with its curious little moustache, so far removed from the Amorino and so admirable a proof of the sculptor's vigilant thoughtfulness in all he did; the relief of the infant John, one of the most animated of the heads (the Baptist at all periods of his life being a favourite with this sculptor); three bronze heads, of which those of the Young Gentleman and the Roman Emperor remain most clearly in my mind. But the authorship of the Roman Emperor is very doubtful. And lastly the glorious Marzocco—the lion from the front of the Palazzo Vecchio, firmly holding the Florentine escutcheon against the world. Florence has other Donatellos—the Judith in the Loggia de' Lanzi, the figures on Giotto's campanile, the Annunciation in S. Croce, and above all the cantoria in the Museum of the Cathedral; but this room holds most of his strong sweet genius. Here (for there are seldom more than two or three persons in it) you can be on terms with him.

After the Donatellos we should see the other Renaissance sculpture. But first the Carrand collection of ivories, pictures, jewels, carvings, vestments, plaquettes, and objets d'art, bequeathed to Florence in 1888. Everything here is good and worth examination. Among the outstanding things is a plaquette, No. 393, a Satyr and a Bacchante, attributed to Donatello, under the title "Allegory of Spring," which is the work of a master and a very riot of mythological imagery. The neighbouring plaquettes, many of them of the school of Donatello, are all beautiful.

We now find the sixth salon, to see Verrocchio's David, of which I have already spoken. This wholly charming boy, a little nearer life perhaps than Donatello's, although not quite so radiantly distinguished, illustrates the association of Verrocchio and Leonardo as clearly as any of the paintings do; for the head is sheer Leonardo. At the Palazzo Vecchio we saw Verrocchio's boy with the dolphin—that happy bronze lyric—and outside Or San Michele his Christ and S. Thomas, in Donatello and Michelozzo's niche, with the flying cherubim beneath. But as with Donatello, so with Verrocchio, one must visit the Bargello to see him, in Florence, most intimately. For here are not only his David, which once known can never be forgotten and is as full of the Renaissance spirit as anything ever fashioned, whether in bronze, marble, or paint, but—upstairs—certain other wonderfully beautiful things to which we shall come, and, that being so, I would like here to say a little about their author.

Verrocchio is a nickname, signifying the true eye. Andrea's real name was de' Cioni; he is known to fame as Andrea of the true eye, and since he had acquired this style at a time when every eye was true enough, his must have been true indeed. It is probable that he was a pupil of Donatello, who in 1435, when Andrea was born, was forty-nine, and in time he was to become the master of Leonardo: thus are the great artists related. The history of Florentine art is practically the history of a family; one artist leads to the other—the genealogy of genius. The story goes that it was the excellence of the angel contributed by Leonardo to his master's picture of the Baptism of Christ (at the Accademia) which decided Verrocchio to paint no more, just as Ghiberti's superiority in the relief of Abraham and Isaac drove Brunelleschi from sculpture. If this be so, it accounts for the extraordinarily small number of pictures by him. Like many artists of his day Verrocchio was also a goldsmith, but he was versatile above most, even when versatility was a habit, and excelled also as a musician. Both Piero de' Medici and Lorenzo employed him to design their tournament costumes; and it was for Lorenzo that he made this charming David and the boy and the dolphin. His greatest work of all is the bronze equestrian statue of Bartolommeo Colleoni in Venice, the finest thing of its kind in the world, and so glorious and exciting indeed that every city should have a cast of it in a conspicuous position just for the good of the people. It was while at work upon this that Verrocchio died, at the age of fifty-three. His body was brought from Venice by his pupil Lorenzo di Credi, who adored him, and was buried in S. Ambrogio in Florence. Lorenzo di Credi painted his portrait, which is now in the Uffizi—a plump, undistinguished-looking little man.

In the David room are also the extremely interesting rival bronze reliefs of Abraham sacrificing Isaac, which were made by Ghiberti and Brunelleschi as trials of skill to see which would win the commission to design the new gates of the Baptistery, as I have told earlier in this book. Six competitors entered for the contest; but Ghiberti's and Brunelleschi's efforts were alone considered seriously. A comparison of these two reliefs proves that Ghiberti, at any rate, had a finer sense of grouping. He filled the space at his disposal more easily and his hand was more fluent; but there is a very engaging vivacity in the other work, the realistic details of which are so arresting as to make one regret that Brunelleschi had for sculpture so little time. In S. Maria Novella is that crucifix in wood which he carved for his friend Donatello, but his only other sculptured work in Florence is the door of his beautiful Pazzi chapel in the cloisters of S. Croce. Of Ghiberti's Baptistery gates I have said more elsewhere. Enough here to add that the episode of Abraham and Isaac does not occur in them.

This little room also has a Cassa Reliquiaria by Ghiberti, below a fine relief by Bertoldo, Michelangelo's master in sculpture, representing a battle between the Romans and the Barbarians; cases of exquisite bronzes; the head, in bronze (No. 25), of an old placid, shrewd woman, executed from a death-mask, which the photographers call Contessina de' Bardi, wife of Cosimo de' Medici, by Donatello, but which cannot be so, since the sculptor died first; heads of Apollo and two babies, over the Ghiberti and Brunelleschi competition reliefs; a crucifixion by Bertoldo; a row of babies representing the triumph of Bacchus; and below these a case of medals and plaquettes, every one a masterpiece.
