There only remained for Pintoricchio to leave a memorial of the coronation of the second Pope of the House of Piccolomini, and this is placed over the door of the Library. It is something like the "Canonisation of St. Catherine," in the way in which it is divided into two parts. The perspective is not well managed. The Pope and the two Cardinals who assist him to place the mitre on his head, have the effect of a picture background to the busy scene below, and the long rows of white-mitred bishops give a very inartistic impression. Below them is a crowd of spectators, of all ages and both sexes--the whole confused and not well drawn, and there is an unfortunate lack of proportion between the different figures. [Illustration: _Alinari photo_] [_Library, Siena_ POPE PIUS II. AT ANCONA] The frescoes have been much retouched, though, on the whole, they are in wonderful preservation. Where the yellows and blues have been most repainted the effect is hard and glaring; but where the same colours are not meddled with, as in the Pope's blue robe, and that of the Doge of No. X., Elizabeth's robe, and the King's mantle in the meeting of the bridal pair, and in most of the pinks and rose-reds, the tones are much softer and more pleasing. Only in the hall itself can we appreciate the way in which the open-air and indoor scenes are arranged and balanced and the architectural setting worked in so as to give lightness and distinction. The line of sight is high, about two-thirds of the way up the picture; this to some extent places the spectator in a wrong position, but the whole goes back, so that, far from being oppressed with a feeling of covered walls, a sense of space and withdrawal is conveyed that enlarges the room in a marvellous manner.
