HE Italian sculptors of the earlier half of the fifteenth century are more than mere forerunners of the great masters of its close, and often reach perfection, within the narrow limits which they chose to impose on their work. Their sculpture shares with the paintings of Botticelli and the churches of Brunelleschi that profound expressiveness, that intimate impress of an indwelling soul, which is the peculiar fascination of the art of Italy in that century. Their works have been much neglected, and often almost hidden away amid the frippery of modern decoration, and we come with some surprise on the places where their fire still smoulders. One longs to penetrate into the lives of the men who have given expression to so much power and sweetness. But it is part of the reserve, the austere dignity and simplicity of their existence, that their histories are for the most part lost, or told but briefly. From their lives, as from their work, all tumult of sound and colour has passed away. Mino, the Raphael of sculpture, Maso del Rodario, whose works add a further grace to [63/64] the church of Como, Donatello even, — one asks in vain for more than a shadowy outline of their actual days.
Something more remains of Luca della Robbia; something more of a history, of outward changes and fortunes, is expressed through his work. I suppose nothing brings the real air of a Tuscan town so vividly to mind as those pieces of pale blue and white earthenware, by which he is best known, like fragments of the milky sky itself, fallen into the cool streets, and breaking into the darkened churches. And no work is less imitable: like Tuscan wine, it loses its savour when moved from its birthplace, from the crumbling walls where it was first placed. Part of the charm of this work, its grace and purity and finish of expression, is common to all the Tuscan sculptors of the fifteenth century; for Luca was first of all a worker in marble, and his works in terra cotta only transfer to a different material the principles of his sculpture.
These Tuscan sculptors of the fifteenth century worked for the most part in low relief, giving even to their monumental effigies something of its depression of surface, getting into them by this means a pathetic suggestion of the wasting and etherealisation of death. They are haters of all heaviness and emphasis, of strongly-opposed light and shade, and seek their means of delineation among those last refinements of shadow, which are almost invisible except in a strong [64/65] light, and which the finest pencil can hardly follow. The whole essence of their work is expression, the passing of a smile over the face of a child, the ripple of the air on a still day over the curtain of a window ajar.
What is the precise value of this system of sculpture, this low relief? Luca della Robbia, and the other sculptors of the school to which he belongs, have before them the universal problem of their art; and this system of low relief is the means by which they meet and overcome the special limitation of sculpture.
That limitation results from the material and other necessary conditions of all sculptured work, and consists in the tendency of such work to a hard realism, a one-sided presentment of mere form, that solid material frame which only motion can relieve, a thing of heavy shadows, and an individuality of expression pushed to caricature. Against this tendency to the hard presentment of mere form trying vainly to compete with the reality of nature itself, all noble sculpture constantly struggles; each great system of sculpture resisting it in its own way, etherealising, spiritualising, relieving its stiffness, its heaviness, and death. The use of colour in sculpture is but an unskilful contrivance to effect, by borrowing from another art, what the nobler sculpture effects by strictly appropriate means.
To get not colour, but the equivalent of colour; to secure the expression and the play of life; to [65/66] expand the too firmly fixed individuality of pure, unrelieved, uncoloured form: — this is the problem which the three great styles in sculpture have solved in three different ways.
Allgemeinheit — breadth, generality, universality, — is the word chosen by Winckelmann, and after him by Goethe and many German critics, to express that law of the most excellent Greek sculptors, of Pheidias and his pupils, which prompted them constantly to seek the type in the individual, to abstract and express only what is structural and permanent, to purge from the individual all that belongs only to him, all the accidents, the feelings and actions of the special moment, all that (because in its own nature it endures but for a moment) is apt to look like a frozen thing if one arrests it.
In this way their works came to be like some subtle extract or essence, or almost like pure thoughts or ideas: and hence the breadth of humanity in them, that detachment from the conditions of a particular place or people, which has carried their influence far beyond the age which produced them, and insured them universal acceptance.
That was the Greek way of relieving the hardness and unspirituality of pure form. But it involved to a certain degree the sacrifice of what we call expression; and a system of abstraction which aimed always at the broad and general type, at the purging away from the [66/67] individual of what belonged only to him, and of the mere accidents of a particular time and place, imposed upon the range of effects open to the Greek sculptor limits somewhat narrowly defined. When Michelangelo came, therefore, with a genius spiritualised by the reverie of the middle age, penetrated by its spirit of inwardness and introspection, living not a mere outward life like the Greek, but a life full of intimate experiences, sorrows, consolations, a system which sacrificed so much of what was inward and unseen could not satisfy him. To him, lover and student of Greek sculpture as he was, work which did not bring what was inward to the surface, which was not concerned with individual expression, with individual character and feeling, the special history of the special soul, was not worth doing at all.
And so, in a way quite personal and peculiar to himself, which often is, and always seems, the effect of accident, he secured for his work individuality and intensity of expression, while he avoided a too heavy realism, that tendency to harden into caricature which the representation of feeling in sculpture is apt to display. What time and accident, its centuries of darkness under the furrows of the "little Melian farm," have done with singular felicity of touch for the Venus of Melos, fraying its surface and softening its lines, so that some spirit in the thing seems always on the point of breaking out, as though [67/68] in it classical sculpture had advanced already one step into the mystical Christian age, its expression being in the whole range of ancient work most like that of Michelangelo's own: — this effect Michelangelo gains by leaving nearly all his sculpture in a puzzling sort of incompleteness, which suggests rather than realises actual form. Something of the wasting of that snow- image which he moulded at the command of Piero de' Medici, when the snow lay one night in the court of the Pitti palace, almost always lurks about it, as if he had determined to make the quality of a task, exacted from him half in derision, the pride of all his work. Many have wondered at that incompleteness, suspecting, however, that Michelangelo himself loved and was loath to change it, and feeling at the same time that they too would lose something if the half-realised form ever quite emerged from the stone, so rough-hewn here, so delicately finished there; and they have wished to fathom the charm of this incompleteness. Well! That incompleteness is Michelangelo's equivalent for colour in sculpture; it is his way of etherealising pure form, of relieving its stiff realism, and communicating to it breath, pulsation, the effect of life. It was a characteristic too which fell in with his peculiar temper and mode of living, his disappointments and hesitations. And it was in reality perfect finish. In this way he combines the utmost amount of passion and intensity with [68/69] the sense of a yielding and flexible life: he gets not vitality merely, but a wonderful force of expression.
Midway between these two systems — the system of the Greek sculptors and the system of Michelangelo — comes the system of Luca della Robbia and the other Tuscan sculptors of the fifteenth century, partaking both of the Allgemeinheit of the Greeks, their way of extracting certain select elements only of pure form and sacrificing all the rest, and the studied incompleteness of Michelangelo, relieving that sense of intensity, passion, energy, which might otherwise have stiffened into caricature. Like Michelangelo, these sculptors fill their works with intense and individualised expression. Their noblest works are the careful sepulchral portraits of particular persons — the monument of Conte Ugo in the Badia of Florence, of the youthful Medea Colleoni, with the wonderful, long throat, in the chapel on the cool north side of the Church of Santa Maria Maggiore at Bergamo — monuments such as abound in the churches of Rome, inexhaustible in suggestions of repose, of a subdued Sabbatic joy, a kind of sacred grace and refinement. And these elements of tranquillity, of repose, they unite to an intense and individual expression by a system of conventionalism as skilful and subtle as that of the Greeks, repressing all such curves as indicate solid form, and throwing the whole into low relief.
 The life of Luca, a life of labour and frugality, with no adventure and no excitement except what belongs to the trial of new artistic processes, the struggle with new artistic difficulties, the solution of purely artistic problems, fills the first seventy years of the fifteenth century. After producing many works in marble for the Duomo and the Campanile of Florence, which place him among the foremost masters of the sculpture of his age, he became desirous to realise the spirit and manner of that sculpture, in a humbler material, to unite its science, its exquisite and expressive system of low relief, to the homely art of pottery, to introduce those high qualities into common things, to adorn and cultivate daily household life. In this he is profoundly characteristic of the Florence of that century, of that in it which lay below its superficial vanity and caprice, a certain old-world modesty and seriousness and simplicity. People had not yet begun to think that what was good art for churches was not so good, or less fitted, for their own houses. Luca's new work was in plain white earthenware at first, a mere rough imitation of the costly, laboriously wrought marble, finished in a few hours. But on this humble path he found his way to a fresh success, to another artistic grace. The fame of the oriental pottery, with its strange, bright colours — colours of art, colours not to be attained in the natural stone — mingled with the tradition of the old Roman [770/71] pottery of the neighbourhood. The little red, coral-like jars of Arezzo, dug up in that district from time to time, are much prized. These colours haunted Luca's fancy. "He still continued seeking something more," his biographer says of him; "and instead of making his figures of baked earth simply white, he added the further invention of giving them colour, to the astonishment and delight of all who beheld them" — Cosa singolare, e multo utile per la state! — a curious thing, and very useful for summer-time, full of coolness and repose for hand and eye. Luca loved the form of various fruits, and wrought them into all sorts of marvellous frames and garlands, giving them their natural colours, only subdued a little, a little paler than nature.
I said that the art of Luca della Robbia possessed in an unusual measure that special characteristic which belongs to all the work- men of his school, a characteristic which, even in the absence of much positive information about their actual history, seems to bring those work-men themselves very near to us. They bear the impress of a personal quality, a profound+ expressiveness, what the French call intimit�, by which is meant some subtler sense of originality — the seal on a man's work of what is most inward and peculiar in his moods, and manner of apprehension: it is what we call expression, carried to its highest intensity of degree. That characteristic is rare in poetry, rarer still [71/72] in art, rarest of all in the abstract art of sculpture; yet essentially, perhaps, it is the quality which alone makes work in the imaginative order really worth having at all. It is because the works of the artists of the fifteenth century possess this quality in an unmistakable way that one is anxious to know all that can be known about them and explain to one's self the secret of their charm.
