=Additional Notes.=--In the _notes upon the pictures_, a large number of additional remarks have been introduced since this _Handbook_ first appeared. These, it is hoped, may serve here and there to deepen the visitor's impression, to suggest fresh points of view, to open up incidental sources of interest. Attention may be called, by way of example, under this head, to several notes upon the designs depicted on the dresses, draperies, and backgrounds of the Italian pictures. These designs, sometimes invented by the artists themselves and sometimes copied from actual stuffs, form a series of examples which illustrate the "art fabrics" of the best period of Italian decorative art, and which might well give hints for the decoration of textile fabrics to-day.[11] Another incidental source of interest in a collection of pictures such as ours, is the historical development of art as it may be traced in the several representations of the same subject by different painters, in successive periods, and in different schools. Such comparisons are instructive to those interested alike in the evolution of art and in the history of religious ideas. In the art of mediæval Christendom we find an unwritten theology, a popular figurative teaching of the sublime story of Christianity blended with the traditions of many generations. On the walls of the National Gallery we may see a series of typical scenes from the Annunciation to the Passion, from the childhood of Christ to His Death, Resurrection, and Ascension, together with ideal forms of apostles and saints. These pictures, contemplated in sequence and compared with one another, afford, as a writer in the _Dublin Review_ (October 1888) has pointed out, a large and interesting field for thought. Very interesting it is also to trace the different types which prevail in the different schools. Thus at Florence, the Madonna is a tender, shrinking, delicate maiden. At Venice, she is a calm, serene, and pure-spirited mother. The Florentine "handmaiden of the Lord" often wears a mystic, and almost always an intellectual air. The Venetian type, seen at its central perfection in Bellini, has a neck firm as a column; the child is nude and plays with a flower or fruit; grandeur of mien and a noble type of motherhood are the ideals the Venetian painters set before themselves. The Lombard Madonna is less spiritual and severe than the Florentine. A refined worldly beauty replaces here the poetic idealism of the Tuscan artists. With the Umbrian painters the model of the Madonna is usually a softly-rounded and very girlish maiden. A certain mystic pensiveness informs her features. Her feet tread this earth, but her soul is absorbed in the contemplation of the infinite.[12] A study of the successive characteristics of Raphael's Madonnas, passing from the vaguely divine to the frankly human, would form material for a volume in itself.[13] In another department of the painter's
