Hitherto I have referred to the creative mind and executive hand as generically the artist. I have thought of him as a type, representative of all the great class of those who feel and express, and who by means of their expression communicate their feeling. Similarly I have spoken of the work of art, as though it were complete in itself and isolated, sprung full-formed and panoplied from the brain of its creator, able to win its way and consummate its destiny alone. The type is conceived intellectually; in actual life the type resolves itself into individuals. So there are individual artists, each with his own distinctive gifts and ideals, each with his own separate experience of life, with his personal and special vision of the world, and his characteristic manner of expression. Similarly, a single work of art is not an isolated phenomenon; it is only a part of the artist's total performance, and to these other works it must be referred. The kind of work an artist sets himself to do is determined to some extent by the period into which he was born and the country in which he lived. The artist himself, heir to the achievements of his predecessors, is a development, and his work is the product of an evolution. A work of art, therefore, to be judged aright and truly appreciated, must be seen in its relation to its background, from which it detaches itself at the moment of consideration,—the background of the artist's personality and accomplishment and of the national life and ideals of his time.
If the layman's interest in art is more than the casual touch-and-go of a picture here, a concert there, and an entertaining book of an evening, he is confronted with the important matter of the study of art as it manifests itself through the ages and in diverse lands. It is not a question of practicing an art himself, for technical skill lies outside his province. The study of art in the sense proposed has to do with the consideration of an individual work in its relation to all the factors that have entered into its production. The work of an artist is profoundly influenced by the national ideals and way of life of his race and of his age. The art of Catholic Italy is ecclesiastical; the art of the Protestant North is domestic and individual. The actual form an artist's work assumes is modified by the resources at his disposal,—resources both of material and of technical methods. Raphael may have no more to say than Giotto had, but he is able to express himself in a fuller and more finished way, because in his time the language of painting had become richer and more varied and the rhetoric of it had been carried to a farther point of development. Finally, as all art is in essence the expression of personality, a single work is to be understood in its widest intention and scope by reference to the total personality of the individual artist as manifested in his work collectively, and to be interpreted by the appreciator through his knowledge of the artist's experience of life.
In order to wrest its fullest expressiveness from a work of art it is necessary as far as possible to regard the work from the artist's own point of view. We must try to see with his eyes and to feel with him what he was working for. To this end we must reconstruct imaginatively on a basis of the facts the conditions in which he lived and wrought. The difference between Giotto and Raphael is a difference not of individuality only. Each gives expression to the ideals and ways of thought of his age. Each is a creative mind, but each bases his performance upon what has gone before, and the form of their work is conditioned by the resources each had at his disposal. To discover the artist's purpose more completely than he was able to realize it for himself in the single work,—that is the aim and function of the historical study of art. A brief review of the achievement of Giotto and of Raphael may serve to illustrate concretely the application of the principle and to fix its value to appreciation.
In the period of the decline and fall of the Roman Empire art passed from Rome to Byzantium. The arts of sculpture and painting were employed in the service of the Church, imposing by its magnificence and all-powerful in its domination over the lives and minds of men. The function of art was to teach; its character was symbolic and decorative. Art had no separate and independent existence. It had no direct reference to nature; the pictorial representation of individual traits was quite outside its scope; a few signs fixed by convention sufficed. A fish—derived from the acrostic ichtbus—symbolized the Saviour; a cross was the visible token of redeeming grace. And so through several hundred years. The twelfth century saw the beginnings of a change in the direction of spiritual and intellectual emancipation. The teachings and example of Francis of Assisi brought men to the consciousness of themselves and to a realization of the worth and significance of the individual life. The work of Giotto is the expression in art of the new spirit.
Of necessity Giotto founded his work upon the accepted forms of the Byzantine tradition. But Giotto was a man of genius and a creative mind. In the expression of his fresh impulse and vital feeling, the assertion of new-found individuality, he tried to realize as convincingly and vividly as possible the situation with which he was dealing; and with this purpose he looked not back upon art but out upon nature. Where the Byzantine convention had presented but a sign and remote indication of form by means of flat color, Giotto endows his figures with life and movement and actuality by giving them a body in three dimensions; his forms exist in the round. Until his day, light and shade had not been employed; and such perspective as he was able to achieve he had to discover for himself. For the first time in Christian painting a figure has bodily existence. Giotto gives the first evidence, too, of a sense of the beauty of color, and of the value of movement as a means of added expressiveness. His power of composition shows an immense advance on his predecessors. In dealing with traditional subjects, as the Madonna and child, he follows in general the traditional arrangement. But in those subjects where his own inventiveness is given free play, as in the series of frescoes illustrating the life of St. Francis, he reveals an extraordinary faculty of design and a dramatic sense which is matched by a directness and clarity of expression.
Not only in the technique of his craft was Giotto an innovator, but also in the direction of naturalness and reality of feeling. He was the first to introduce portraits into his work. His Madonnas and saints are no longer mere types; they are human and individual, vividly felt and characterized by immediate and present actuality. Giotto was the first realist, but he was a poet too. His insight into life is tempered by a deep sincerity and piety; his work is genuinely and powerfully felt. As a man Giotto was reverent and earnest, joyous and beautifully sane. As a painter, by force of the freshness of his impulse and the clarity of his vision, he created a new manner of expression. As an artist he reveals a true power of imaginative interpretation. The casual spectator of to-day finds him naive and quaint. In the eyes of his contemporaries he was anything but that; they regarded him as a marvel of reality, surpassing nature itself. When judged with reference to the conditions of life in which he worked and to the technical resources at his command, Giotto is seen to be of a very high order of creative mind.
The year 1300 divides the life of Giotto into two nearly equal parts; the year 1500 similarly divides the life of Raphael. In the two centuries that intervene, the great age of Italian painting, initiated by Giotto, reaches its flower and perfection in Michelangelo, Leonardo, and Raphael. The years which followed the passing of these greatnesses were the years of decadence and eclipse. If we are to understand and justly appreciate the work of each man in its own kind, the painting of Giotto must be tried by other standards than those we apply to the judgment of Raphael. Giotto was a pioneer; Raphael is a consummation. The two centuries between were a period of development and change, a development in all that regards technique, a change in national ideals and in the artist's attitude toward life and toward his art. A quick survey of the period, if so hasty a generalization permits correctness of statement, will help us in the understanding of the craft and art of Raphael.
Giotto was succeeded by a host of lesser men, regarded as his followers, men who sought to apply the principles and methods of painting worked out by the master, but who lacked his inspiration and his power. Thus it was for nearly a hundred years. The turn of the fourteenth century into the fifteenth saw the emergence of new forces in the science and the mechanics of painting. The laws of perspective and foreshortening were made the object of special research and practice by men like Uccello (1397-1475), Piero dei Franceschi (1416-1492), and Mantegna (1431-1506). "Oh, what a beautiful thing this perspective is!" Uccello exclaimed, as he stood at his desk between midnight and dawn while his wife begged him to take some rest. In the first thirty years of the fifteenth century, Masaccio contributed to the knowledge of anatomy by his painting of the nude form; and the study of the nude was continued by Pollaiuolo and Luca Signorelli, in the second half of the century. Masaccio, also, was the first to place his figures in air, enveloping them in atmosphere. Verrocchio, a generation later than Masaccio, was one of the first of the Florentines to understand landscape and the part played in it by air and light. The realistic spirit, which suffices itself with subjects drawn from every-day actual experience, finds expression in the first half of the fifteenth century in the work of Andrea del Castagno. And so down through that century of spring and summer. Each painter in his own way carries some detail of his craft to a further point of development and prepares the path for the supreme triumphs of Michelangelo, Leonardo, and Raphael.
The growing mastery of the principles and technique of painting accompanied a change in the painter's attitude toward his art. Originally, painting, applied in subjection to architecture and employed in the service of the Church, was decorative in scope; its purpose was illustration, its function was to teach. As painters, from generation to generation, went deeper into the secrets of their craft, they became less interested in the didactic import of their work, and they concerned themselves more and more with its purely artistic significance. Religious subjects were no longer used merely as symbols for the expression of piety and as incitements to devotion; they became inherently artistic motives, valued as they furnished the artist an opportunity for the exercise of his knowledge and skill and for the exhibition of lovely color and significant form. A change in the mechanical methods of painting, also, had its influence on a change in the conception of the function of art. With a very few exceptions, the works of Giotto were executed in fresco as wall decorations. The principles of mural painting require that the composition shall be subordinated to the architectural conditions of the space it is to fill and that the color shall be kept flat. The fresco method meets these requirements admirably, but because of its flatness it has its limitations. The introduction of an oil vehicle for the pigment material, in the fifteenth century, made possible a much greater range in gradated color, and reinforcing the increased knowledge of light and shade, aided in the evolution of decoration into the "easel picture," complete in itself. Released from its subjection to architecture, increasing its technical resources, and widening its interests in the matter of subject so as to include all life, painting becomes an independent and self-sufficing art.
Coincident with the development of painting as a craft, a mighty change was working itself out in the national ideals and in men's ways of thought and feeling. Already in Giotto's time the spirit of individualism had begun to assert itself in reaction from the dominance of an all-powerful restrictive ecclesiasticism, but the age was still essentially pietistic and according to its lights, religious. The fifteenth century witnessed the emancipation from tradition. The new humanism, which took its rise with the rediscovery of Greek culture, extended the intellectual horizon and intensified the enthusiasm for beauty. Men's interest in life was no longer narrowly religious, but human; their art became the expression of the new spirit. Early Christianity had been ascetic, enjoining negation of life and the mortification of the flesh. The men of the Renaissance, with something of the feeling of the elder Greeks, glorified the body and delighted in the pride of life. Pagan myths and Greek legends take their place alongside of Bible episodes and stories of saints and martyrs, as subjects of representation; all served equally as motives for the expression of the artist's sense of the beauty of this world.
