I have not thought it necessary to distinguish between tempera and fresco. In tempera painting the colours were mixed with egg, gum, and other vehicles dissolved in water, and laid upon a dry ground. In fresco painting the colours, mixed only with water, were laid upon plaster while still damp. The latter process replaced the former for wall-paintings in the fourteenth century.

After the splendid outburst of painting in the first half of the fourteenth century, there came a lull. The thoughts and sentiments of mediæval Italy had been now set forth in art. The sincere and simple style of Giotto was worked out. But the new culture of the Revival had not as yet sufficiently penetrated the Italians for the painters to express it; nor had they mastered the technicalities of their craft in such a manner as to render the delineation of more complex forms of beauty possible. The years between 1400 and 1470 may be roughly marked out as the second period of great, activity in painting. At this time sculpture, under the hands of Ghiberti, Donatello, and Luca della Robbia, had reached a higher point than the sister art. The debt the sculptors owed to Giotto, they now repaid in full measure to his successors, in obedience to the law whereby sculpture, though subordinated, as in Italy, to painting, is more precocious in its evolution. One of the most marked features of this period was the progress in the art of design, due to bronze modelling and bas-relief; for the painters, labouring in the workshops of the goldsmiths and the stone-carvers, learned how to study the articulation of the human body, to imitate the nude, and to aim by means of graduated light and dark at rendering the effect of roundness in their drawing. The laws of perspective and foreshortening were worked out by Paolo Uccello and Brunelleschi. New methods of colouring were attempted by the Peselli and the Pollajuoli. Abandoning the conventional treatment of religious themes, the artists began to take delight in motives drawn from everyday experience. It became the fashion to introduce contemporary costumes, striking portraits, and familiar incidents into sacred subjects, so that many pictures of this period, though worthless to the student of religious art, are interesting for their illustration of Florentine custom and character. At the same time the painters began to imitate landscape and architecture, loading the background of their frescoes with pompous vistas of palaces and city towers, or subordinating their figures to fantastic scenery of wood and rock and seashore. Many were naturalists, delighting, like Gentile da Fabriano, in the delineation of field flowers and living creatures, or, like Piero di Cosimo, in the portrayal of things rare and curious. Gardens please their eyes, and birds and beasts and insects. Whole menageries and aviaries, for instance, were painted by Paolo Uccello. Others, again, abandoned the old ground of Christian story for the tales of Greece and Rome; and not the least charming products of the time are antique motives treated with the freshness of romantic feeling. We look in vain for the allegories of the Giottesque masters: that stage of thought has been traversed, and a new cycle of poetic ideas, fanciful, idyllic, corresponding to Boiardo's episodes rather than to Dante's vision, opens for the artist. Instead of seeking to set forth vast subjects with the equality of mediocrity, like the Gaddi, or to invent architectonic compositions embracing the whole culture of their age, like the Lorenzetti, the painters were now bent upon realising some special quality of beauty, expressing some fantastic motive, or solving some technical problem of peculiar difficulty. They had, in fact, outgrown the childhood of their art; and while they had not yet attained to mastery, had abandoned the impossible task of making it the medium of universal expression. In this way the manifold efforts of the workers in the first half of the fifteenth century prepared the ground for the great painters of the Golden Age. It remained for Raphael and his contemporaries to achieve the final synthesis of art in masterpieces of consummate beauty. But this they could not have done without the aid of those innumerable intermediate labourers, whose productions occupy in art the place of Bacon's media axiomata in science. Remembering this, we ought not to complain that the purpose of painting at this epoch was divided, or that its achievements were imperfect. The whole intellectual conditions of the country were those of growth, experiment, preparation, and acquisition, rather than of full accomplishment. What happened in the field of painting, was happening also in the field of scholarship; and we have good reason to be thankful that by the very nature of the arts, these tentative endeavours have a more enduring charm than the dull tomes of contemporary students. Nor, again, is it rational to regret that painting, having started with the sincere desire of expressing the hopes and fears that agitate the soul of man, and raise him to a spiritual region, should now be occupied with lessons in perspective and anatomy. In the twofold process of discovering the world and man, this dry ground had inevitably to be explored, and its exploration could not fail to cost the sacrifice of much that was impassioned and imaginative in the earlier and less scientific age of art.[[161]] The spirit of Cosimo de' Medici, almost cynical in its positivism, the spirit of Sixtus IV., almost godless in its egotism, were abroad in Italy at this period;[[162]] indeed, the fifteenth century presents at large a spectacle of prosaic worldliness and unideal aims. Yet the work done by the artists was the best work of the epoch, far more fruitful of results and far more permanently valuable than that of Filelfo inveighing in filthy satires against his personal foes, or of Beccadelli endeavouring to inoculate modern literature with the virus of pagan vices. Petrarch in the fourteenth century had preached the evangel of humanism; Giotto in the fourteenth century had given life to painting. The students of the fifteenth, though their spirit was so much baser and less large than Petrarch's, were following in the path marked out for them and leading forward to Erasmus. The painters of the fifteenth, though they lacked the unity of aim and freshness of their master, were learning what was needful for the crowning and fulfilment of his labours on a loftier stage.
Foremost among the pioneers of Renaissance-painting, towering above them all by head and shoulders, like Saul among the tribes of Israel, stands Masaccio.[[163]] The Brancacci Chapel of the Carmine at Florence, painted in fresco almost entirely by his hand, was the school where all succeeding artists studied, and whence Raphael deigned to borrow the composition and the figures of a portion of his Cartoons. The "Legend of S. Catherine," painted by Masaccio in 8. Clemente at Rome, though an earlier work, is scarcely less remarkable as evidence that a new age had begun for art. In his frescoes the qualities essential to the style of the Renaissance—what Vasari calls the modern manner—appear precociously full-formed. Besides life and nature they have dignity and breadth, the grand and heightened manner of emancipated art. Masaccio is not inferior to Giotto in his power of telling a story with simplicity; but he understands the value of perspective for realising the circumstances of the scene depicted. His august groups of the Apostles are surrounded by landscape tranquillising to the sense and pleasant to the eye. Mountain-lines and distant horizons lend space and largeness to his compositions, and the figures of his men and women move freely in a world prepared for them. In Masaccio's management of drapery we discern the influence of plastic art; without concealing the limbs, which are always modelled with a freedom that suggests the power of movement even in stationary attitudes, the voluminous folds and broad masses of powerfully coloured raiment invest his forms with a nobility unknown before in painting. His power of representing the nude is not less remarkable. But what above all else renders his style attractive is the sense of aërial space. For the first time in art the forms of living persons are shown moving in a transparent medium of light, graduated according to degrees of distance, and harmonised by tones that indicate an atmospheric unity. In comparing Masaccio with Giotto we must admit that, with so much gained, something has been sacrificed. Giotto succeeded in presenting the idea, the feeling, the pith of the event, and pierced at once to the very ground-root of imagination. Masaccio thinks over-much, perhaps, of external form, and is intent on air-effects and colouring. He realises the phenomenal truth with a largeness and a dignity peculiar to himself. But we ask whether he was capable of bringing close to our hearts the secret and the soul of spiritual things. Has not art beneath his touch become more scenic, losing thereby somewhat of dramatic poignancy?
Born in 1402, Masaccio left Florence in 1429 for Rome, and was not heard of by his family again. Thus perished, at the early age of twenty-seven, a painter whose work reveals not only the originality of real creative genius, but a maturity that moves our wonder. What might he not have done if he had lived? Between his style in the Brancacci chapel and that of Raphael in the Vatican there seems to be but a narrow gap, which might perchance have been passed over by this man, if death had spared him.
Masaccio can by no means be taken as a fair instance of the painters of his age. Gifted with exceptional powers, he overleaped the difficulties of his art, and arrived intuitively at results whereof as yet no scientific certainty had been secured. His contemporaries applied humbler talents to severe study, and wrought out by patient industry those principles which Masaccio had divined. Their work is therefore at the same time more archaic and more pedantic, judged by modern standards. It is difficult to imagine a style of painting less attractive than that of Paolo Uccello.[[164]] Yet his fresco of the "Deluge" in the cloisters of S. Maria Novella, and his battlepieces—one of which may be seen in the National Gallery—taught nearly all that painters needed of perspective. The lesson was conveyed in hard, dry, uncouth diagrams, ill-coloured and deficient in the quality of animation. At this period the painters, like the sculptors, were trained as goldsmiths, and Paolo had been a craftsman of that guild before he gave his whole mind to the study of linear perspective and the drawing of animals. The precision required in this trade forced artists to study the modelling of the human form, and promoted that crude naturalism which has been charged against their pictures. Carefully to observe, minutely to imitate some actual person—the Sandro of your workshop or the Cecco from the marketplace—became the pride of painters. No longer fascinated by the dreams of mediæval mysticism, and unable for the moment to invest ideals of the fancy with reality, they meanwhile made the great discovery that the body of a man is a miracle of beauty, each limb a divine wonder, each muscle a joy as great as sight of stars or flowers. Much that is repulsive in the pictures of the Pollajuoli and Andrea del Castagno, the leaders in this branch of realism, is due to admiration for the newly studied mechanism of the human form. They seem to have cared but little to select their types or to accentuate expression, so long as they were able to portray the man before them with fidelity.[[165]] The comeliness of average humanity was enough for them; the difficulties of reproducing what they saw, exhausted their force. Thus the master-works on which they staked their reputation show them emulous of fame as craftsmen, while only here and there, in minor paintings for the most part, the poet that was in them sees the light. Brunelleschi told Donatello the truth when he said that his Christ was a crucified contadino. Intent on mastering the art of modelling, and determined above all things to be accurate, the sculptor had forgotten that something more was wanted in a crucifix than the careful study of a robust peasant-boy.
