VI
While seeking to characterise what proved pernicious to contemporaries in Michelangelo's work as architect, I have been led to concentrate attention upon the Library at S. Lorenzo. This was logical; for, as we have seen, Vasari regarded that building as the supreme manifestation of his manner. Vasari never saw the cupola of S. Peter's in all its glory, and it may be doubted whether he was capable of learning much from it.
The sacristy demands separate consideration. It was an earlier work, produced under more favourable conditions of place and space, and is in every way a purer specimen of the master's style. As Vasari observed, the Laurentian Library indicated a large advance upon the sacristy in the development of Michelangelo's new manner.
At this point it may not unprofitably be remarked, that none of the problems offered for solution at S. Lorenzo were in the strictest sense of that word architectural. The façade presented a problem of pure panelling. The ground-plan of the sacristy was fixed in correspondence with Brunelleschi's; and here again the problem resolved itself chiefly into panelling. A builder of genius, working on the library, might indeed have displayed his science and his taste by some beautiful invention adapted to the awkward locality; as Baldassare Peruzzi, in the Palazzo Massimo at Rome, converted the defects of the site into graces by the exquisite turn he gave to the curved portion of the edifice. Still, when the scheme was settled, even the library became more a matter of panelling and internal fittings than of structural design. Nowhere at S. Lorenzo can we affirm that Michelangelo enjoyed, the opportunity of showing what he could achieve in the production of a building independent in itself and planned throughout with a free hand. Had he been a born architect, he would probably have insisted upon constructing the Medicean mausoleum after his own conception instead of repeating Brunelleschi's ground-plan, and he would almost certainly have discovered a more genial solution for the difficulties of the library. But he protested firmly against being considered an architect by inclination or by education. Therefore he accepted the most obvious conditions of each task, and devoted himself to schemes of surface decoration.
The interior of the sacristy is planned with a noble sense of unity. For the purpose of illuminating a gallery of statues, the lighting may be praised without reserve; and there is no doubt whatever that Michelangelo intended every tabernacle to be filled with figures, and all the whitewashed spaces of the walls to be encrusted with bas-reliefs in stucco or painted in fresco. The recesses or niches, taking the form of windows, are graduated in three degrees of depth to suit three scales of sculptural importance. The sepulchres of the Dukes had to emerge into prominence; the statues subordinate to these main masses occupied shallower recesses; the shallowest of all, reserved for minor statuary, are adorned above with garlands, which suggest the flatness of the figures to be introduced. Architecturally speaking, the building is complete; but it sadly wants the plastic decoration for which it was designed, together with many finishing touches of importance. It is clear, for instance, that the square pedestals above the double pilasters flanking each of the two Dukes were meant to carry statuettes or candelabra, which would have connected the marble panelling with the cornices and stucchi and frescoed semicircles of the upper region. Our eyes are everywhere defrauded of the effect calculated by Michelangelo when he planned this chapel. Yet the total impression remains harmonious. Proportion has been observed in all the parts, especially in the relation of the larger to the smaller orders, and in the balance of the doors and windows. Merely decorative carvings are used with parsimony, and designed in a pure style, although they exhibit originality of invention. The alternation of white marble surfaces and mouldings with pietra serena pilasters, cornices, and arches, defines the structural design, and gives a grave but agreeable sense of variety. Finally, the recess behind the altar adds lightness and space to what would otherwise have been a box. What I have already observed when speaking of the vestibule to the library must be repeated here: the whole scheme is that of an exterior turned outside in, and its justification lies in the fact that it demanded statuary and colour for its completion. Still the bold projecting cornices, the deeper and shallower niches resembling windows, have the merit of securing broken lights and shadows under the strong vertical illumination, all of which are eminently picturesque. No doubt remains now that tradition is accurate in identifying the helmeted Duke with Lorenzo de' Medici, and the more graceful seated hero opposite with Giuliano. The recumbent figures on the void sepulchres beneath them are with equal truth designated as Night and Day, Morning and Evening. But Michelangelo condescended to no realistic portraiture in the statues of the Dukes, and he also meant undoubtedly to treat the phases of time which rule man's daily life upon the planet as symbols for far-reaching thoughts connected with our destiny. These monumental figures are not men, not women, but vague and potent allegories of our mortal fate. They remain as he left them, except that parts of Giuliano's statue, especially the hands, seem to have been worked over by an assistant. The same is true of the Madonna, which will ever be regarded, in her imperfectly finished state, as one of the finest of his sculptural conceptions. To Montelupo belongs the execution of S. Damiano, and to Montorsoli that of S. Cosimo. Vasari says that Tribolo was commissioned by Michelangelo to carve statues of Earth weeping for the loss of Giuliano, and Heaven rejoicing over his spirit. The death of Pope Clement, however, put a stop to these subordinate works, which, had they been accomplished, might perhaps have shown us how Buonarroti intended to fill the empty niches on each side of the Dukes.
When Michelangelo left Florence for good at the end of 1534, his statues had not been placed; but we have reason to think that the Dukes and the four allegorical figures were erected in his lifetime. There is something singular in the maladjustment of the recumbent men and women to the curves of the sarcophagi, and in the contrast between the roughness of their bases and the smooth polish of the chests they rest on. These discrepancies do not, however, offend the eye, and they may even have been deliberately adopted from a keen sense of what the Greeks called asymmetreia as an adjunct to effect. It is more difficult to understand what he proposed to do with the Madonna and her two attendant saints. Placed as they now are upon a simple ledge, they strike one as being too near the eye, and out of harmony with the architectural tone of the building. It is also noticeable that the saints are more than a head taller than the Dukes, while the Madonna overtops the saints by more than another head. We are here in a region of pure conjecture; and if I hazard an opinion, it is only thrown out as a possible solution of a now impenetrable problem. I think, then, that Michelangelo may have meant to pose these three figures where they are, facing the altar; to raise the Madonna upon a slightly projecting bracket above the level of SS. Damiano and Cosimo, and to paint the wall behind them with a fresco of the Crucifixion. That he had no intention of panelling that empty space with marble may be taken for granted, considering the high finish which has been given to every part of this description of work in the chapel. Treated as I have suggested, the statue of the Madonna, with the patron saints of the House of Medici, overshadowed by a picture of Christ's sacrifice, would have confronted the mystery of the Mass during every celebration at the altar. There are many designs for the Crucifixion, made by Michelangelo in later life, so lofty as almost to suggest a group of figures in the foreground, cutting the middle distance.
At the close of Michelangelo's life the sacristy was still unfinished. It contained the objects I have described—the marble panelling, the altar with its candelabra, the statues of the Dukes and their attendant figures, the Madonna and two Medicean patron saints—in fact, all that we find there now, with the addition of Giovanni da Udine's frescoes in the cupola, the relics of which have since been buried under cold Florentine whitewash.
All the views I have advanced in the foregoing paragraphs as to the point at which Michelangelo abandoned this chapel, and his probable designs for its completion, are in the last resort based upon an important document penned at the instance of the Duke of Florence by Vasari to Buonarroti, not long before the old man's death in Rome. This epistle has so weighty a bearing upon the matter in hand that I shall here translate it. Careful study of its fluent periods will convince an unprejudiced mind that the sacristy, as we now see it, is even less representative of its maker's design than it was when Vasari wrote. The frescoes of Giovanni da Udine are gone. It will also show that the original project involved a wealth of figurative decoration, statuary, painting, stucco, which never arrived at realisation.
