I
THE RISE OF CHRISTIAN ART
What do I mean by a slope? That I hope to make clear in the course of this chapter and the next. But, as readers may expect something to go on with, I will explain immediately that, though I recognise the continuity of the stream of art, I believe that it is possible and proper to divide that stream into slopes and movements. About the exact line of division there can be no certainty. It is easy to say that in the passage of a great river from the hills to the sea, the depth, the width, the colour, the temperature, and the velocity of the waters are bound to change; to fix precisely the point of change is another matter. If I try to picture for myself the whole history of art from earliest times in all parts of the world I am unable, of course, to see it as a single thread. The stuff of which it is made is unchangeable, it is always water that flows down the river, but there is more than one channel: for instance, there is European art and Oriental. To me the universal history of art has the look of a map in which several streams descend from the same range of mountains to the same sea. They start from different altitudes but all descend at last to one level. Thus, I should say that the slope at the head of which stand the Buddhist masterpieces of the Wei, Liang, and T'ang dynasties begins a great deal higher than the slope at the head of which are the Greek primitives of the seventh century, and higher than that of which early Sumerian sculpture is the head; but when we have to consider contemporary Japanese art, Graeco-Roman and Roman sculpture, and late Assyrian, we see that all have found the same sea-level of nasty naturalism.
By a slope, then, I mean that which lies between a great primitive morning, when men create art because they must, and that darkest hour when men confound imitation with art. These slopes can be subdivided into movements. The downward course of a slope is not smooth and even, but broken and full of accidents. Indeed the procession of art does not so much resemble a river as a road from the mountains to the plain. That road is a sequence of ups and downs. An up and a down together form a movement. Sometimes the apex of one movement seems to reach as high as the apex of the movement that preceded it, but always its base carries us farther down the slope. Also, in the history of art the summit of one movement seems always to spring erect from the trough of its predecessor. The upward stroke is vertical, the downward an inclined plane. For instance, from Duccio to Giotto is a step up, sharp and shallow. From Giotto to Lionardo is a long and, at times, almost imperceptible fall. Duccio is a fine decadent of that Basilian movement which half survived the Latin conquest and came to an exquisite end under the earlier Palaeologi. The peak of that movement rises high above Giotto, though Duccio near its base is below him. Giotto's art is definitely inferior to the very finest Byzantine of the eleventh and twelfth centuries, and Giotto is the crest of a new movement destined and doomed inevitably to sink to depths undreamed of by Duccio.
All that was spiritual in Greek civilisation was sick before the sack of Corinth, and all that was alive in Greek art had died many years earlier. That it had died before the death of Alexander let his tomb at Constantinople be my witness. Before they set the last stone of the Parthenon it was ailing: the big marbles in the British Museum are the last significant examples of Greek art; the frieze, of course, proves nothing, being mere artisan work. But the man who made what one may as well call "The Theseus" and "The Ilissus," the man whom one may as well call Phidias, crowns the last vital movement in the Hellenic slope. He is a genius, but he is no oddity: he falls quite naturally into his place as the master of the early decadence; he is the man in whom runs rich and fast but a little coarsened the stream of inspiration that gave life to archaic Greek sculpture. He is the Giotto—but an inferior Giotto—of the slope that starts from the eighth century b.c.—so inferior to the sixth century a.d.—to peter out in the bogs of Hellenistic and Roman rubbish. Whence sprang that Hellenic impulse? As yet we cannot tell. Probably, from the ruins of some venerable Mediterranean civility, against the complex materialism of which it was, in its beginnings, I dare say, a reaction. The story of its prime can be read in fragments of archaic sculpture scattered throughout Europe, and studied in the National Museum at Athens, where certain statues of athletes, dating from about 600, reveal the excellences and defects of Greek art at its best. Of its early decline in the fifth century Phidias is the second-rate Giotto; the copies of his famous contemporaries and immediate predecessors are too loathsome to be at all just; Praxiteles, in the fourth century, the age of accomplished prettiness, is the Correggio, or whatever delightful trifler your feeling for art and chronology may suggest. Fifth and fourth century architecture forbid us to forget the greatness of the Greeks in the golden age of their intellectual and political history. The descent from sensitive, though always rather finikin, drawing through the tasteful and accomplished to the feebly forcible may be followed in the pots and vases of the sixth, fifth, fourth, and third centuries. In the long sands and flats of Roman realism the stream of Greek inspiration is lost for ever.
Before the death of Marcus Aurelius, Europe was as weary of materialism as England before the death of Victoria. But what power was to destroy a machine that had enslaved men so completely that they dared not conceive an alternative? The machine was grown so huge that man could no longer peer over its side; man could see nothing but its cranks and levers, could hear nothing but its humming, could mark the spinning fly-wheel and fancy himself in contemplation of the revolving spheres. Annihilation was the only escape for the Roman citizen from the Roman Empire. Yet, while in the West Hadrian was raising the Imperial talent for brutalisation to a system and a science, somewhere in the East, in Egypt, or in Asia Minor, or, more probably in Syria, in Mesopotamia, or even Persia, the new leaven was at work. That power which was to free the world was in ferment. The religious spirit was again coming to birth. Here and there, in face of the flat contradiction of circumstances, one would arise and assert that man does not live by bread alone. Orphism, Mythraism, Christianity, many forms of one spirit, were beginning to mean something more than curious ritual and discreet debauch. Very slowly a change was coming over the face of Europe.
There was change before the signs of it became apparent. The earliest Christian paintings in the catacombs are purely classical. If the early Christians felt anything new they could not express it. But before the second century was out Coptic craftsmen had begun to weave into dead Roman designs something vital. The academic patterns are queerly distorted and flattened out into forms of a certain significance, as we can feel for ourselves if we go to the textile room at South Kensington. Certainly, these second century Coptic textiles are more like works of art than anything that had been produced in the Roman Empire for more than four hundred years. Egyptian paintings of the third century bear less positive witness to the fumblings of a new spirit. But at the beginning of the fourth century Diocletian built his palace at Spalato, where we have all learned to see classicism and the new spirit from the East fighting it out side by side; and, if we may trust Strzygowski, from the end of that century dates the beautiful church of Kodja-Kalessi in Isauria. The century in which the East finally dominated the West (350-450) is a period of incubation. It is a time of disconcerting activity that precedes the unmistakable launch of art upon the Christian slope. I would confidently assert that every artistic birth is preceded by a period of uneasy gestation in which the unborn child acquires the organs and energy that are to carry it forward on its long journey, if only I possessed the data that would give a tottering support to so comforting a generalisation. Alas! the births of the great slopes of antiquity are shrouded in a night scarcely ruffled by the minute researches of patient archaeologists and impervious to the startling discoveries by experts of more or less palpable forgeries. Of these critical periods we dare not speak confidently; nevertheless we can compare the fifth century with the nineteenth and draw our own conclusions.
In 450 they built the lovely Galla Placidia at Ravenna. It is a building essentially un-Roman; that is to say, the Romanism that clings to it is accidental and adds nothing to its significance. The mosaics within, however, are still coarsely classical. There is a nasty, woolly realism about the sheep, and about the good shepherd more than a suspicion of the stodgy, Graeco-Roman, Apollo. Imitation still fights, though it fights a losing battle, with significant form. When S. Vitale was begun in 526 the battle was won. Sta. Sophia at Constantinople was building between 532 and 537; the finest mosaics in S. Vitale, S. Apollinare-Nuovo and S. Apollinare-in-Classe belong to the sixth century; so do SS. Sergius and Bacchus at Constantinople and the Duomo at Parenzo. In fact, to the sixth century belong the most majestic monuments of Byzantine art. It is the primitive and supreme summit of the Christian slope. The upward spring from the levels of Graeco-Romanism is immeasurable. The terms in which it could be stated have yet to be discovered. It is the whole length of the slope from Sta. Sophia to the Victoria Memorial pushed upright to stand on a base of a hundred years. We are on heights from which the mud-flats are invisible; resting here, one can hardly believe that the flats ever were, or, at any rate, that they will ever be again. Go to Ravenna, and you will see the masterpieces of Christian art, the primitives of the slope: go to the Tate Gallery or the Luxembourg, and you will see the end of that slope—Christian art at its last gasp. These memento mori are salutary in an age of assurance when, looking at the pictures of Cézanne, we feel, not inexcusably, that we are high above the mud and malaria. Between Cézanne and another Tate Gallery, what lies in store for the human spirit? Are we in the period of a new incubation? Or is the new age born? Is it a new slope that we are on, or are we merely part of a surprisingly vigorous premonitory flutter? These are queries to ponder. Is Cézanne the beginning of a slope, a portent, or merely the crest of a movement? The oracles are dumb. This alone seems to me sure: since the Byzantine primitives set their mosaics at Ravenna no artist in Europe has created forms of greater significance unless it be Cézanne.
