This is the history of the first attack of the Renaissance upon the Gothic schools, and of its rapid results, more fatal and immediate in architecture than in any other art, because there the demand for perfection was less reasonable, and less consistent with the capabilities of the workman; being utterly opposed to that rudeness or savageness on which, as we saw above, the nobility of the elder schools in great part depends. But inasmuch as the innovations were founded on some of the most beautiful examples of art, and headed by some of the greatest men that the world ever saw, and as the Gothic with which they interfered was corrupt and valueless, the first appearance of the Renaissance feeling had the appearance of a healthy movement. A new energy replaced whatever weariness or dulness had affected the Gothic mind; an exquisite taste and refinement, aided by extended knowledge, furnished the first models of the new school; and over the whole of Italy a style arose, generally now known as cinque-cento, which in sculpture and painting, as I just stated, produced the noblest masters which the world ever saw, headed by Michael Angelo, Raphael, and Leonardo; but which failed of doing the same in architecture, because, as we have seen above, perfection is therein not possible, and failed more totally than it would otherwise have done, because the classical enthusiasm had destroyed the best types of architectural form. § XVII. For, observe here very carefully, the Renaissance principle, as it consisted in a demand for universal perfection, is quite distinct from the Renaissance principle as it consists in a demand for classical and Roman _forms_ of perfection. And if I had space to follow out the subject as I should desire, I would first endeavor to ascertain what might have been the course of the art of Europe if no manuscripts of classical authors had been recovered, and no remains of classical architecture left, in the fifteenth century; so that the executive perfection to which the efforts of all great men had tended for five hundred years, and which now at last was reached, might have been allowed to develope itself in its own natural and proper form, in connexion with the architectural structure of earlier schools. This refinement and perfection had indeed its own perils, and the history of later Italy, as she sank into pleasure and thence into corruption, would probably have been the same whether she had ever learned again to write pure Latin or not. Still the inquiry into the probable cause of the enervation which might naturally have followed the highest exertion of her energies, is a totally distinct one from that into the particular form given to this enervation by her classical learning; and it is matter of considerable regret to me that I cannot treat these two subjects separately: I must be content with marking them for separation in the mind of the reader.
