This last is the perfect type of aperture protection. None other can ever be invented so good. It is that once employed by Giotto in the cathedral of Florence, and torn down by the proveditore, Benedetto Uguccione, to erect a Renaissance front instead; and another such has been destroyed, not long since, in Venice, the porch of the church of St. Apollinare, also to put up some Renaissance upholstery: for Renaissance, as if it were not nuisance enough in the mere fact of its own existence, appears invariably as a beast of prey, and founds itself on the ruin of all that is best and noblest. Many such porches, however, happily still exist in Italy, and are among its principal glories. [Illustration: Fig. L.] § VII. When porches of this kind, carried by walls, are placed close together, as in cases where there are many and large entrances to a cathedral front, they would, in their general form, leave deep and uncomfortable intervals, in which damp would lodge and grass grow; and there would be a painful feeling in approaching the door in the midst of a crowd, as if some of them might miss the real doors, and be driven into the intervals, and embayed there. Clearly it will be a natural and right expedient, in such cases, to open the walls of the porch wider, so that they may correspond in slope, or nearly so, with the bevel of the doorway, and either meet each other in the intervals, or have the said intervals closed up with an intermediate wall, so that nobody may get embayed in them. The porches will thus be united, and form one range of great open gulphs or caverns, ready to receive all comers, and direct the current of the crowd into the narrower entrances. As the lateral thrust of the arches is now met by each other, the pinnacles, if there were any, must be removed, and waterspouts placed between each arch to discharge the double drainage of the gables. This is the form of all the noble northern porches, without exception, best represented by that of Rheims.
