Nor is there at Manchester any picture by Duccio da Siena, the great, and, one may almost say, the worthy contemporary of Giotto, from which his power and feeling are to be well estimated. Like Giotto he struggled to free himself from the swathing-clothes in which the traditions of Byzantine Art had bound up the limbs and the imaginations of artists, and he succeeded in at last breaking loose. But the long restraint had impaired the power of all who were subjected to it; and as in the works of Giotto, so in the rarer works of Duccio, one often finds an effort after truth of expression, which is almost pathetic in its character, from its revealing the inefficiency of the hand to carry out the thought, and the resolute will striving half in vain to overcome the impediments of bad teaching and imperfect knowledge of the materials and limits of painting. It is this groping effort after truth which results often in the _naïve_ rendering of details, and the quaintness of composition, which are so common in the works of these early masters; but the deep feeling of the artists penetrates through all, and thus even their awkward and imperfect drawing frequently produces a stronger effect, and seems a better rendering of nature, than the cold, unfeeling, academic accuracy of Bologna, or all the finished science of the eclectic schools. In passing down through the century one finds lamentable omissions at Manchester. Fifty pictures, of which half at least have been restored, (that is to say, in part or wholly spoiled,) and half originally the work of inferior masters, do not represent the art of a century which was full of the glow of reawakening life, and which, as the spring covers the earth with flowers, covered Italy with cathedrals, campaniles, churches, baptisteries, and camposantos, and decorated their walls with sculpture and painting. Art was gaining gradually a knowledge of her own powers. Orgagna, the Michel Angelo of his time, (one of his pictures is at Manchester,) was opening a wider field for her progress; and ten years after his death Fra Angelico was born. He was a boy of fifteen years old when in 1402 Masaccio was born at Florence, and the brightness of the fifteenth century had begun.
