The most notable sculpture in the Baptistery is the tomb of the ex-Pope John XXIII, whose licentiousness was such that there was nothing for it but to depose and imprison him. He had, however, much money, and on his liberation he settled in Florence, presented a true finger of John the Baptist to the Baptistery, and arranged in return for his bones to repose in that sanctuary. One of his executors was that Niccolò da Uzzano, the head of the noble faction in the city, whose coloured bust by Donatello is in the Bargello. The tomb is exceedingly fine, the work of Donatello and his partner Michelozzo, who were engaged to make it by Giovanni de' Medici, the ex-pontiff's friend, and the father of the great Cosimo. The design is all Donatello's, and his the recumbent cleric, lying very naturally, hardly as if dead at all, a little on one side, so that his face is seen nearly full; the three figures beneath are Michelozzo's; but Donatello probably carved the seated angels who display the scroll which bears the dead Pope's name. The Madonna and Child above are by Donatello's assistant, Pagno di Lapo Portigiani, a pretty relief by whom we saw in the Museum of the Cathedral. Being in red stone, and very dusty, like Ghiberti's doors (which want the hose regularly), the lines of the tomb are much impaired. Donatello is also represented here by a Mary Magdalene in wood, on an altar at the left of the entrance door, very powerful and poignant.
In the ordinary way, when visitors to Florence speak of the Baptistery doors they mean those opposite the Duomo, and when they go to the Bargello and look at the designs made by Ghiberti and Brunelleschi in competition, they think that the competition was for those. But that is wrong. Ghiberti won his spurs with the doors on the north side, at which comparatively few persons look. The famous doors opposite the Duomo were commissioned many years later, when his genius was acknowledged and when he had become so accomplished as to do what he liked with his medium. Before, however, coming to Ghiberti, we ought to look at the work of an early predecessor but for whom there might have been no Ghiberti at all; for while Ghiberti was at work with his assistants on these north doors, between 1403 and 1424, the place which they occupy was filled by those executed seventy years earlier by Andrea Pisano (1270–1348), possibly from Giotto's designs, which are now at the south entrance, opposite the charming little loggia at the corner of the Via Calzaioli, called the Bigallo. These represent twenty scenes in the life of S. John the Baptist, and below them are eight figures of cardinal and Christian virtues, and they employed their sculptor from 1330 to 1336. They have three claims to notice: as being admirably simple and vigorous in themselves; as having influenced all later workers in this medium, and particularly Ghiberti and Donatello; and as being the bronze work of the sculptor of certain of the stone scenes round the base of Giotto's campanile. The panel in which the Baptist is seen up to his waist in the water is surely the very last word in audacity in bronze. Ghiberti was charged with making bronze do things that it was ill fitted for; but I do not know that even he moulded water—and transparent water—from it.
The year 1399 is one of the most notable in the history of modern art, since it was then that the competition for the Baptistery gates was made public, this announcement being the spring from which many rivers flowed. In that year Lorenzo Ghiberti, a young goldsmith assisting his father, was twenty-one, and Filippo Brunelleschi, another goldsmith, was twenty-two, while Giotto had been dead sixty-three years and the impulse he had given to painting had almost worked itself out. The new doors were to be of the same shape and size as those by Andrea Pisano, which were already getting on for seventy years old, and candidates were invited to make a specimen relief to scale, representing the interrupted sacrifice of Isaac, although the subject-matter of the doors was to be the Life of S. John the Baptist. Among the judges was that Florentine banker whose name was beginning to be known in the city as a synonym for philanthropy, enlightenment, and sagacity, Giovanni de' Medici. In 1401 the specimens were ready, and after much deliberation as to which was the better, Ghiberti's or Brunelleschi's—assisted, some say, by Brunelleschi's own advice in favour of his rival—the award was given to Ghiberti, and he was instructed to proceed with his task; while Brunelleschi, as we have seen, being a man of determined ambition, left for Rome to study architecture, having made up his mind to be second to no one in whichever of the arts and crafts he decided to pursue. Here then was the first result of the competition—that it turned Brunelleschi to architecture.
Ghiberti began seriously in 1408 and continued till 1424, when the doors were finished; but, in order to carry out the work, he required assistance in casting and so forth, and for that purpose engaged among others a sculptor named Donatello (born in 1386), a younger sculptor named Luca della Robbia (born in 1400), and a gigantic young painter called Masaccio (born in 1401), each of whom was destined, taking fire no doubt from Ghiberti and his fine free way, to be a powerful innovator—Donatello (apart from other and rarer achievements) being the first sculptor since antiquity to place a statue on a pedestal around which observers could walk; Masaccio being the first painter to make pictures in the modern use of the term, with men and women of flesh and blood in them, as distinguished from decorative saints, and to be by example the instructor of all the greatest masters, from his pupil Lippo Lippi to Leonardo and Michelangelo; and Luca della Robbia being the inspired discoverer of an inexpensive means of glazing terra-cotta so that his beautiful and radiant Madonnas could be brought within the purchasing means of the poorest congregation in Italy. These alone are remarkable enough results, but when we recollect also that Brunelleschi's defeat led to the building of the cathedral dome, the significance of the event becomes the more extraordinary.
The doors, as I say, were finished in 1424, after twenty-one years' labour, and the Signoria left the Palazzo Vecchio in procession to see their installation. In the number and shape of the panels Pisano set the standard, but Ghiberti's work resembled that of his predecessor very little in other ways, for he had a mind of domestic sweetness without austerity and he was interested in making everything as easy and fluid and beautiful as might be. His thoroughness recalls Giotto in certain of his frescoes. The impression left by Pisano's doors is akin to that left by reading the New Testament; but Ghiberti makes everything happier than that. Two scenes—both on the level of the eye—I particularly like: the "Annunciation," with its little, lithe, reluctant Virgin, and the "Adoration". The border of the Pisano doors is, I think, finer than that of Ghiberti's; but it is a later work.
Looking at them even now, with eyes that remember so much of the best art that followed them and took inspiration from them, we can understand the better how delighted Florence must have been with this new picture gallery and how the doors were besieged by sightseers. But greater still was to come. Ghiberti at once received the commission to make two more doors on his own scale for the south side of the Baptistery, and in 1425 he had begun on them. These were not finished until 1452, so that Ghiberti, then a man of seventy-four, had given practically his whole life to the making of four bronze doors. It is true that he did a few other things besides, such as the casket of S. Zenobius in the Duomo, and the Baptist and S. Matthew for Or San Michele; but he may be said justly to live by his doors, and particularly by the second pair, although it was the first pair that had the greater effect on his contemporaries and followers.
Among his assistants on these were Antonio Pollaiuolo (born in 1429), who designed the quail in the left border, and Paolo Uccello (born in 1397), both destined to be men of influence. The bald head on the right door is a portrait of Ghiberti; that of the old man on the left is his father, who helped him to polish the original competition plaque. Although commissioned for the south side they were placed where they now are, on the east, as being most worthy of the position of honour, and Pisano's doors, which used to be here, were moved to the south, where they now are.
On Ghiberti's workshop opposite S. Maria Nuova, in the Via Bufalini, the memorial tablet mentions Michelangelo's praise—that these doors were beautiful enough to be the Gates of Paradise. After that what is an ordinary person to say? That they are lovely is a commonplace. But they are more. They are so sensitive; bronze, the medium which Horace has called, by implication, the most durable of all, has become in Ghiberti's hands almost as soft as wax and tender as flesh. It does all he asks; it almost moves; every trace of sternness has vanished from it. Nothing in plastic art that we have ever seen or shall see is more easy and ingratiating than these almost living pictures.
Before them there is steadily a little knot of admirers, and on Sundays you may always see country people explaining the panels to each other. Every one has his favourite among
