– Luca Della Robbia
by
THE 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 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 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.
