There she is, of course, looking down on us from the great window above the high altar, where we never forget her presence! Is there a thought of disturbance there? Around the curve of the choir are seven great windows, without roses, filling the whole semicircle and the whole vault, forty-seven feet high, and meant to dominate the nave as far as the western portal, so that we may never forget how Mary fills her church without being disturbed by quarrels, and may understand why Saint Ferdinand and Saint Louis creep out of our sight, close by the Virgin's side, far up above brawls; and why France and Brittany hide their ugly or their splendid passions at the ends of the transepts, out of sight of the high altar where Mary is to sit in state as Queen with the young King on her lap. In an instant she will come, but we have a moment still to look about at the last great decoration of her palace, and see how the artists have arranged it. Since the building of Sancta Sofia, no artist has had such a chance. No doubt, Rheims and Amiens and Bourges and Beauvais, which are now building, may be even finer, but none of them is yet finished, and all must take their ideas from here. One would like, before looking at it, to think over the problem, as though it were new, and so choose the scheme that would suit us best if the decoration were to be done for the first time. The architecture is fixed; we have to do only with the colour of this mass of seven huge windows, forty-seven feet high, in the clerestory, round the curve of the choir, which close the vista of the church as viewed from the entrance. This vista is about three hundred and thirty feet long. The windows rise above a hundred feet. How ought this vast space to be filled? Should the perpendicular upward leap of the architecture be followed and accented by a perpendicular leap of colour? The decorators of the fifteenth and sixteenth centuries seem to have thought so, and made perpendicular architectural drawings in yellow that simulated gold, and lines that ran with the general lines of the building. Many fifteenth-century windows seem to be made up of florid Gothic details rising in stages to the vault. No doubt critics complained, and still complain, that the monotony of this scheme, and its cheapness of intelligence, were objections; but at least the effect was light, decorative, and safe. The artist could not go far wrong and was still at liberty to do beautiful work, as can be seen in any number of churches scattered broadcast over Europe and swarming in Paris and France. On the other hand, might not the artist disregard the architecture and fill the space with a climax of colour? Could he not unite the Roses of France and Dreux above the high altar in an overpowering outburst of purples and reds? The seventeenth century might have preferred to mass clouds and colours, and Michael Angelo, in the sixteenth, might have known how to do it. What we
