co-ordination of detail, greatness of proportions, and, most of all, perhaps, by quite marvellous distribution of light. These small squares, or octagons, most often with a square embrasure for the altar, seem ample habitations for the greatest things; one would wish to use them for Palestrina's music, or Bach's, or Handel's; and then one recognises that their actual dimensions in yards would not accommodate the band and singers and the organ! Such music must remain in our soul, where, in reality, the genius of those Florentine architects has contrived the satisfying ampleness of their buildings. That they invented nothing in the way of architectural ornament, nay, took their capitals, flutings, cornices, and so forth, most mechanically from the worst antique, should be no real drawback to this architecture; it was, most likely, a matter of negative instinct. For these meagre details leave the mind free, nay, force it rather, to soar at once into the vaultings, into the serene middle space opposite the windows, and up into the enclosed heaven of the cupolas. VI. The Tuscan sculpture of this period stands, I think, midway between the serene perfection of the buildings (being itself sprung from the architecture of the Gothic time), and the splendid but fragmentary accomplishment of the paintings, many of whose disturbing problems, of anatomy and anatomic movement, it shared to its confusion. It is not for beautiful bodily structure or gesture, such as we find even in poor antiques, that we should go to the Florentine sculptors, save, perhaps, the two Robbias. It is the almost architectural distribution of space and light, the treatment of masses, which makes the immeasurable greatness of Donatello, and gives dignity to his greatest contemporary, Jacopo della Quercia. And it is again an architectural quality, though in the sense of the carved portals of Pistoia, the flutings and fretwork and surface pattern of the Baptistery and S. Miniato, which gives such poignant pleasure in the work of a very different, but very great, sculptor, Desiderio. The marvel (for it is a marvel) of his great monument in Santa Croce, depends not on anatomic forms, but on the exquisite variety and vivacity of surface arrangement; the word symphony (so often misapplied) fitting exactly this complex structure of minute melodies and harmonies of rhythms and accents in stone. But the quality of Tuscan sculpture exists in humbler, often anonymous and infinitely pathetic work. I mean those effigies of knights and burghers, coats of arms and mere inscriptions, which constitute so large a portion of what we walk upon in Santa Croce. Things not much thought of, maybe, and ruthlessly defaced by all posterity. But the masses, the main lines, were originally noble, and defacement has only made their nobleness and tenderness more evident and poignant: they have come to partake of the special solemnity of stone worn by frost and sunshine.
