Vasari, in a well-known passage of his Life of Michelangelo, reports the general opinion of his age regarding the novelties introduced by Buonarroti into Italian architecture. The art of building was in a state of transition. Indeed, it cannot be maintained that the Italians, after they abandoned the traditions of the Romanesque manner, advanced with certitude on any line of progress in this art. Their work, beautiful as it often is, ingenious as it almost always is, marked invariably by the individuality of the district and the builder, seems to be tentative, experimental. The principles of the Pointed Gothic style were never seized or understood by Italian architects. Even such cathedrals as those of Orvieto and Siena are splendid monuments of incapacity, when compared with the Romanesque churches of Pisa, S. Miniato, S. Zenone at Verona, the Cathedral of Parma. The return from Teutonic to Roman standards of taste, which marked the advent of humanism, introduced a hybrid manner. This, in its first commencement, was extremely charming. The buildings of Leo Battista Alberti, of Brunelleschi, and of Bramante are distinguished by an exquisite purity and grace combined with picturesqueness. No edifice in any style is more stately, and at the same time more musical in linear proportions, than the Church of S. Andrea at Mantua. The Cappella dei Pazzi and the Church of S. Spirito at Florence are gems of clear-cut and harmonious dignity. The courtyard of the Cancelleria at Rome, the Duomo at Todi, show with what supreme ability the great architect of Casteldurante blended sublimity with suavity, largeness and breadth with naïveté and delicately studied detail. But these first endeavours of the Romantic spirit to assimilate the Classic mannerism—essays no less interesting than those of Boiardo in poetry, of Botticelli in painting, of Donatello and Omodei in sculpture—all of them alike, whether buildings, poems, paintings, or statues, displaying the genius of the Italic race, renascent, recalcitrant against the Gothic style, while still to some extent swayed by its influence (at one and the same time both Christian and chivalrous, Pagan and precociously cynical; yet charmingly fresh, unspoiled by dogma, uncontaminated by pedantry)—these first endeavours of the Romantic spirit to assimilate the Classic mannerism could not create a new style representative of the national life. They had the fault inherent in all hybrids, however fanciful and graceful. They were sterile and unprocreative. The warring elements, so deftly and beautifully blent in them, began at once to fall asunder. The San Galli attempted to follow classical precedent with stricter severity. Some buildings of their school may still be reckoned among the purest which remain to prove the sincerity of the Revival of Learning. The Sansovini exaggerated the naïveté of the earlier Renaissance manner, and pushed its picturesqueness over into florid luxuriance or decorative detail. Meanwhile, humanists and scholars worked slowly but steadily upon the text of Vitruvius, impressing the paramount importance of his theoretical writings upon practical builders. Neither students nor architects reflected that they could not understand Vitruvius; that, if they could understand him, it was by no means certain he was right; and that, if he was right for his own age, he would not be right for the sixteenth century after Christ. It was just at this moment, when Vitruvius began to dominate the Italian imagination, that Michelangelo was called upon to build. The genial adaptation of classical elements to modern sympathies and uses, which had been practised by Alberti, Brunelleschi, Bramante, yielded now to painful efforts after the appropriation of pedantic principles. Instead of working upon antique monuments with their senses and emotions, men approached them through the medium of scholastic erudition. Instead of seeing and feeling for themselves, they sought by dissection to confirm the written precepts of a defunct Roman writer. This diversion of a great art from its natural line of development supplies a striking instance of the fascination which authority exercises at certain periods of culture. Rather than trust their feeling for what was beautiful and useful, convenient and attractive, the Italians of the Renaissance surrendered themselves to learning. Led by the spirit of scholarship, they thought it their duty to master the text of Vitruvius, to verify his principles by the analysis of surviving antique edifices, and, having formed their own conception of his theory, to apply this, as well as they were able, to the requirements of contemporary life.
Two exits from the false situation existed: one was the picturesqueness of the Barocco style; the other was the specious vapid purity of the Palladian. Michelangelo, who was essentially the genius of this transition, can neither be ascribed to the Barocco architects, although he called them into being, nor yet can he be said to have arrived at the Palladian solution. He held both types within himself in embryo, arriving at a moment of profound and complicated difficulty for the practical architect; without technical education, but gifted with supreme genius, bringing the imperious instincts of a sublime creative amateur into every task appointed him. We need not wonder if a man of his calibre left the powerful impress of his personality upon an art in chaos, luring lesser craftsmen into the Barocco mannerism, while he provoked reaction in the stronger, who felt more scientifically what was needed to secure firm standing-ground. Bernini and the superb fountain of Trevi derive from Michelangelo on one side; Vignola's cold classic profiles and Palladio's resuscitation of old Rome in the Palazzo della Ragione at Vicenza emerge upon the other. It remained Buonarroti's greatest-glory that, lessoned by experience and inspired for high creation by the vastness of the undertaking, he imagined a world's wonder in the cupola of S. Peter's.
