Dante, and his successors Petrarch and Boccaccio, were called “Humanists,” for the reason that they studied and advocated the knowledge that was needful to man in his progress and in relation to his life in this world, and did not confine themselves wholly to theology, which was the case with those who devoted themselves to learning in the Middle Ages. This led to a wider spread of knowledge among the people, which was greatly stimulated by the invention of printing. The rulers of the people also encouraged learning and promoted the arts to an extent unknown before. In Florence, especially, under the powerful and beneficent rule of the Medici family, art and literature received every attention, and made rapid progress in every department of cultured knowledge and skilful handicraft.
Great artists like Niccola Pisano, Brunellesco, Donatello, Giotto, Alberti, and others of the early period, whose individuality and great personality did more than anything else to bring about the epoch and the art of the Renaissance, studied with evident purpose the existing remains of the art of Ancient Rome. In this they only followed the movement of the day in every branch of art and learning: all classes in every walk of life were then directing their footsteps to Rome in the pursuit of knowledge. About the year 1414 the discovery was made in the Monastery of St. Gall of the celebrated codex of Vitruvius, a work wherein the learned writer had set forth the principles of Roman architecture of the Augustan era. This work was reprinted later at Rome, and was very much used by architects as a guide for the better understanding of the Roman temples and other buildings. As the Gothic style in France, Germany, and in England was approaching its climax, the art of the Renaissance in Italy was developing, and the period of decadence in the former was contemporaneous with the finest period of the latter—towards the end of the fifteenth century. The transition, or early beginnings of the Renaissance, has been called the Trecento (1300) style, which in its ornamental features is characterised by a free use of conventional foliage, mixed with Saracenic or with Byzantine ornament, interlacings, and scroll work; in sculpture and painting by a closer study of nature and of antique remains, with an endeavour to shake off the former stiff Byzantine traditions; and in architecture by the use of the round arch and a revival of some other features of the classic orders. Niccola Pisano, Arnolfo di Lapo, Orcagna, and Giotto were some of its exponents.
The next division is known as the Quattrocento (1400), which is more properly the early form of the Renaissance. To this period belong the real founders of the style: Filippo Brunellesco (1377-1446), Lorenzo Ghiberti (1381-1455), and Donatello (1386-1468); the former more particularly in architecture, and the latter two in sculpture. The ornament of the Quattrocento period—the fifteenth century—is distinguished by its prominence of elaborate natural forms in festoons, scroll work, and other compositions; all the ornament was decoratively arranged more or less geometrically, but the details and actual working out were closely copied from nature. The bronze gates of the Baptistery of San Giovanni (1425-52) are the finest examples of the Quattrocento style, both as regards ornament and figure work. The modelled work in high relief of fruit, flowers, and foliage on these gates, and similar work on great medallions and altar-pieces of Luca della Robbia (1355-1430) is characteristic of this style. These natural forms, mixed with tracery ornamentation, acanthus foliage, treated in symmetrical arrangements, and occasionally cartouche or strap-work, were used in the Italian ornament of this period. The panel forms were usually Byzantine, but the rest of the ornament had no symbolic meaning. Besides Luca della Robbia, the name of Jacopo dell’ Quercia (1374-1438), the Sienese sculptor, may be mentioned as one who executed some of the finest work in figure and ornament in the above style.
The Cinquecento style (1500) was the culminatory effort of the Renaissance. It is the art of Italy in the sixteenth century, and is entirely devoid of symbolism in its ornament. Although the difference is great in the matter of style between the classic ornament of the Greeks and that of the Italian Cinquecento, yet in their aim and expression they are identical, for in both there is the same striving to reach the highest possible æsthetic ideal, the same delight in the production of beautiful lines and forms for their own sakes, and a similar expression of appropriate fitness—the outcome of a correct conformity to architectural principles—pervades the ornament of both styles.
Returning to the art of the early Renaissance, we have to mention two great names, already referred to—Giotto in painting, and Niccola Pisano in sculpture, who may be justly called the harbingers of the new era of Italian art. The latter was the first to go to the antique for his inspiration and style in sculpture. It appears—according to Vasari—that in Pisa there had been accumulated a great collection of antique sculpture—the spoils of war—and among them a sarcophagus, on which the "Hunt of Meleager and the Calydonian boar "was wrought with great skill, which was placed for ornament on the façade of the Cathedral: this and other antique remains in the city were studied to great advantage by Niccola, to the great improvement of his style. One fine work of his, executed in the spirit of the antique, was the pulpit for the Church of San Giovanni in Pisa, on which are great numbers of figures, representing the Universal Judgment. For the Cathedral of Siena he also executed a similar work with subjects from various passages in the life of Christ. On this pulpit he had the assistance of Arnolfo and Lapo, his pupils, and probably also that of his son Giovanni. These works proved the great turning-point in sculpture, from the archaic productions of the Middle Ages to an era of better things, although in execution they left much to be desired. Giotto was not only the great painter who first invested his works with poetry, feeling, and expression, but was also a skilful architect, as his fine Campanile, or bell-tower, in his native city of Florence bears witness. Dante and Petrarch were his friends, the former especially so; the portrait of Dante by Giotto still exists in the Chapel of the Podesta at Florence.
Brunellesco, as we learn from Vasari, was one of the most interesting of men, and one of the most capable artists of his time, a man of acute genius and ready resource. In the early Renaissance period architecture was studied by nearly all sculptors and painters, and many, as we have seen, were apprenticed in their youth as goldsmiths. Brunellesco was no exception to this rule, for we find that he was a clever goldsmith and worker in niello.
The greatest work of his life was the building of the cupola or dome of the Cathedral of Florence—he was the only architect of his day that was found able to do it. The Cathedral was the work of the Florentine architect, Arnolfo di Lapo, the foundations of which were laid in the year 1298. Brunellesco also built the sacristy and dome on the Church of San Lorenzo, which was decorated with sculpture by Donatello, and was the architect of the Pitti Palace, besides many other works. He gained his knowledge of the construction of domes in Rome, more particularly from that of the Pantheon, having drawn from and made models of the domes of all that was worth copying of the ancient remains at Rome, in company with his friend Donatello, the sculptor.
The latter, with Brunellesco, Ghiberti, and a few other sculptors, competed with their designs for the work of making the celebrated bronze doors of the Baptistery of San Giovanni at Florence, when Ghiberti’s design was adjudged the best, and of which Michelangelo at a later period said, when speaking of the gates, that they were “fit to be the gates of Paradise.” Brunellesco’s design was good, was more restrained in character, and was more consistent with correct architectural principles than Ghiberti’s; but the latter’s design was so fresh and so vigorous, that in spite of its being too picturesque for sculpture it won universal admiration.
The next great name in architecture is that of Leon Battista Alberti (1404-1472), who naturally follows Brunellesco. His most complete work is the Rucellai Palace at Florence; he built and restored many churches, tombs, and palaces; was a great mathematician, and very learned in Latin, in which language he wrote poems, plays, and treatises on painting and architecture.
