As for the Palace of the Bourse, which is Greek as to its colonnade, Roman in the round arches of its doors and windows, of the Renaissance by virtue of its flattened vault, it is indubitably a very correct and very pure monument; the proof is that it is crowned with an attic, such as was never seen in Athens, a beautiful, straight line, gracefully broken here and there by stovepipes. Let us add that if it is according to rule that the architecture of a building should be adapted to its purpose in such a manner that this purpose shall be immediately apparent from the mere aspect of the building, one cannot be too much amazed at a structure which might be indifferently--the palace of a king, a chamber of communes, a town-hall, a college, a riding-school, an academy, a warehouse, a court-house, a museum, a barracks, a sepulchre, a temple, or a theatre. However, it is an Exchange. An edifice ought to be, moreover, suitable to the climate. This one is evidently constructed expressly for our cold and rainy skies. It has a roof almost as flat as roofs in the East, which involves sweeping the roof in winter, when it snows; and of course roofs are made to be swept. As for its purpose, of which we just spoke, it fulfils it to a marvel; it is a bourse in France as it would have been a temple in Greece. It is true that the architect was at a good deal of trouble to conceal the clock face, which would have destroyed the purity of the fine lines of the façade; but, on the other hand, we have that colonnade which circles round the edifice and under which, on days of high religious ceremony, the theories of the stock-brokers and the courtiers of commerce can be developed so majestically.
These are very superb structures. Let us add a quantity of fine, amusing, and varied streets, like the Rue de Rivoli, and I do not despair of Paris presenting to the eye, when viewed from a balloon, that richness of line, that opulence of detail, that diversity of aspect, that grandiose something in the simple, and unexpected in the beautiful, which characterizes a checker-board.
However, admirable as the Paris of to-day may seem to you, reconstruct the Paris of the fifteenth century, call it up before you in thought; look at the sky athwart that surprising forest of spires, towers, and belfries; spread out in the centre of the city, tear away at the point of the islands, fold at the arches of the bridges, the Seine, with its broad green and yellow expanses, more variable than the skin of a serpent; project clearly against an azure horizon the Gothic profile of this ancient Paris. Make its contour float in a winter's mist which clings to its numerous chimneys; drown it in profound night and watch the odd play of lights and shadows in that sombre labyrinth of edifices; cast upon it a ray of light which shall vaguely outline it and cause to emerge from the fog the great heads of the towers; or take that black silhouette again, enliven with shadow the thousand acute angles of the spires and gables, and make it start out more toothed than a shark's jaw against a copper-colored western sky,--and then compare.
