The name of Verocchio is best known to the world through the equestrian statue of Bartolommeo Colleoni. When this great Condottiere, the last surviving general trained by Braccio da Montone, died in 1475, he bequeathed a large portion of his wealth to Venice, on condition that his statue on horseback should be erected in the Piazza di S. Marco. Colleoni, having long held the bâton of the Republic, desired that after death his portrait, in his habit as he lived, should continue to look down on the scene of his old splendour. By an ingenious quibble the Senators adhered to the letter of his will without infringing a law that forbade them to charge the square of S. Mark with monuments. They ruled that the piazza in front of the Scuola di S. Marco, better known as the Campo di S. Zanipolo, might be chosen as the site of Colleoni's statue, and to Andrea Verocchio was given the commission for its erection.
Andrea died in 1488 before the model for the horse was finished. The work was completed, and the pedestal was supplied by Alessandro Leopardi. To Verocchio, profiting by the example of Donatello's "Gattamelata," must be assigned the general conception of this statue; but the breath of life that animates both horse and rider, the richness of detail that enhances the massive grandeur of the group, and the fiery spirit of its style of execution were due to the Venetian genius of Leopardi. Verocchio alone produced nothing so truly magnificent. This joint creation of Florentine science and Venetian fervour is one of the most precious monuments of the Renaissance. From it we learn what the men who fought the bloodless battles of the commonwealths, and who aspired to principality, were like. "He was tall," writes a biographer of Colleoni,[[94]] "of erect and well-knit figure, and of well-proportioned limbs. His complexion tended rather to brown, marked withal by bright and sanguine flesh-tints. He had black eyes; their brilliancy was vivid, their gaze terrible and penetrating. In the outline of his nose and in all his features he displayed a manly nobleness combined with goodness and prudence." Better phrases cannot be chosen to describe his statue.
While admiring this masterpiece and dwelling on its royal style, we are led to deplore most bitterly the loss of the third equestrian statue of the Renaissance. Nothing now remains but a few technical studies made by Lionardo da Vinci for his portrait of Francesco Sforza. The two elaborate models he constructed and the majority of his minute designs have been destroyed. He intended, we are told, to represent the first Duke of the Sforza dynasty on his charger, trampling the body of a prostrate and just conquered enemy. Rubens' transcript from the "Battle of the Standard," enables us to comprehend to some extent how Lionardo might have treated this motive. The severe and cautious style of Donatello, after gaining freedom and fervour from Leopardi, was adapted to the ideal presentation of dramatic passion by Lionardo. Thus Gattamelata, Colleoni, and Francesco Sforza would, through their statues, have marked three distinct phases in the growth of art. The final effort of Italian sculpture to express human activity in the person of a mounted warrior has perished. In this sphere we possess nothing which, like the tombs of S. Lorenzo in relation to sepulchral statuary, completes a series of development.
If Donatello founded no school, this was far more the case with Ghiberti. His supposed pupil, Antonio del Pollajuolo, showed no sign of Ghiberti's influence, but struck out for himself a style distinguished by almost brutal energy and bizarre realism—characteristics the very opposite to those of his master. If the bronze relief of the "Crucifixion" in the Bargello be really Pollajuolo's, we may even trace a leaning to Verocchio in his manner. The emphatic passion of the women recalls the group of mourners round the death-bed of Selvaggia Tornabuoni in Verocchio's celebrated bas-relief. Pollajuolo, like so many Florentine artists, was a goldsmith, a painter, and a worker in niello, before he took to sculpture. As a goldsmith he is said to have surpassed all his contemporaries, and his mastery over this art influenced his style in general. What we chiefly notice, however, in his choice of subjects is a frenzy of murderous enthusiasm, a grimness of imagination, rare among Italian artists. The picture in the Uffizzi of "Hercules and Antæus" and the well-known engraving of naked men fighting a series of savage duels in a wood, might be chosen as emphatic illustrations of his favourite motives. The fiercest emotions of the Renaissance find expression in the clenched teeth, strained muscles, knotted brows, and tense nerves, depicted by Pollajuolo with eccentric energy. We seem to be assisting at some of those combats a steccato chiuso wherein Sixtus IV. delighted, or to have before our eyes a fray between Crocensi and Vallensi in the streets of Rome.[[95]] The same remarks apply to the terra-cotta relief by Pollajuolo in the South Kensington Museum. This piece displays the struggles of twelve naked men, divided into six pairs of combatants. Two of the couples hold short chains with the left hand, and seek to stab each other with the right. In the case of another two couples the fight is over, and the victor is insulting his fallen foe. In each of the remaining pairs one gladiator is on the point of yielding to his adversary. There are thus three several moments of duel to the death, each illustrated by two couples. The mathematical distribution of these dreadful groups gives an effect of frozen passion; while the vigorous workmanship displays not only an enthusiasm for muscular anatomy, but a real sympathy with blood-fury in the artist.
There was, therefore, a certain propriety in the choice of Pollajuolo to cast the sepulchre of Sixtus IV. in bronze at Rome. The best judges complain, not without reason, that the allegories surrounding this tomb are exaggerated and affected in style; yet the dead Pope, stretched in pomp upon his bier, commands more than merely historical interest; while the figures, seated as guardians round the old man, terrible in death, communicate an impression of monumental majesty. Criticised in detail, each separate figure may be faulty. The composition, as a whole, is picturesque and grandiose. The same can scarcely be said about the tomb of Innocent VIII., erected by Antonio and his brother Piero del Pollajuolo. While it perpetuates the memory of an uninteresting Pontiff, it has but little, as a work of art, to recommend it. The Pollajuoli were not great sculptors. In the history of Italian art they deserve a place, because of the vivid personality impressed upon some portions of their work. Few draughtsmen carried the study of muscular anatomy so far as Antonio.[[96]]
Luca della Robbia, whose life embraced the first eighty years of the fifteenth century, offers in many important respects a contrast to his contemporaries Ghiberti and Donatello, and still more to their immediate followers. He made his art as true to life as it is possible to be, without the rugged realism of Donatello or the somewhat effeminate graces of Ghiberti. The charm of his work is never impaired by scientific mannerism—that stumbling-block to critics like De Stendhal in the art of Florence; nor does it suffer from the picturesqueness of a sentimental style. How to render the beauty of nature in her most delightful moments—taking us with him into the holiest of holies, and handling the sacred vessels with a child's confiding boldness—was a secret known to Luca della Robbia alone. We may well find food for meditation in the innocent and cheerful inspiration of this man, whose lifetime coincided with a period of sordid passions and debased ambition in the Church and States of Italy.
Luca was apprenticed in his youth to a goldsmith; but of what he wrought before the age of forty-five, we know but little.[[97]] At that time his faculty had attained full maturity, and he produced the groups of dancing children and choristers intended for the organ gallery of the Duomo. Wholly free from affectation, and depending for effect upon no merely decorative detail, these bas-reliefs deserve the praise bestowed by Dante on the sculpture seen in Purgatory:[[98]]—
Dinanzi a noi pareva si verace,
Quivi intagliato in un atto soave,
Che non sembrava immagine che tace.
