after the men of the sixteenth century have been enabled to completely realise all that the men of the fourteenth century had indicated, that art, with Michelangelo, Tintoret, and still more with the great painters of Spain and Flanders, proceeds to encounter problems of foreshortening, of light and shade, of atmospheric effect, that could never have been imagined by the contemporaries of Giotto, nor even by the contemporaries of Ghirlandaio and the Bellini. Hence, throughout the fifteenth century, while there is a steady development of the artistic means required to realise those narrative themes which the Giottesques had invented, there is no introduction of any new artistic means unnecessary for this result, but which, like the foreshortenings of Michelangelo, and the light and shade of Tintoret, like the still further additions to painting represented by men like Velasquez and Rembrandt, could suggest new treatment of the old histories and enable the well-known events to be shown from totally new intellectual standpoints, and in totally new artistic arrangements. If we look into the matter, we shall recognise that the monotony of representation throughout the Renaissance can be amply accounted for without referring to the fact, which, however, doubtless went for something, that the men of the fifteenth century were too much absorbed in the working out of details to feel any desire for new pictorial versions of the stories of the Gospel, and the lives of the Saints. Moreover, the Giottesques--among whom I include the immediate precursors, sculptors as well as painters, of Giotto--put into their Scripture stories an amount of logic, of sentiment, of dramatic and psychological observation and imagination more than sufficient to furnish out the works of three generations of later comers. Setting aside Giotto himself, who concentrates and diffuses the vast bulk of dramatic invention as well as of artistic observation and skill, there is in even the small and smallest among his followers, an extraordinary happiness of individual invention of detail. I may quote a few instances at random. It would be difficult to find a humbler piece of work than the so-called Tree of the Cross, in the Florentine Academy: a thing like a huge fern, with medallion histories in each frond, it can scarcely be considered a work of art, and stands halfway between a picture and a genealogical tree. Yet in some of its medallions there is a great vivacity of imaginative rendering; for instance, the Massacre of the Innocents represented by a single soldier, mailed and hooded, standing before Herod on a floor strewn with children's bodies, and holding up an infant by the arm, like a dead hare, preparing slowly to spit it on his sword; and the kiss of Judas, the soldiers crowding behind, while the traitor kisses Christ, seems to bind him hand and foot with his embraces, to give him up, with that stealthy look backwards to the impatient rabble--a representation
