Since Michelangelo was now engaged upon the Medicean tombs at S. Lorenzo, it will be well to give some account of the several plans he made before deciding on the final scheme, which he partially executed. We may assume, I think, that the sacristy, as regards its general form and dimensions, faithfully represents the first plan approved by Clement. This follows from the rapidity and regularity with which the structure was completed. But then came the question of filling it with sarcophagi and statues. As early as November 28, 1520, Giulio de' Medici, at that time Cardinal, wrote from the Villa Magliana. to Buonarroti, addressing him thus: "Spectabilis vir, amice noster charissime." He says that he is pleased with the design for the chapel, and with the notion of placing the four tombs in the middle. Then he proceeds to make some sensible remarks upon the difficulty of getting these huge masses of statuary into the space provided for them. Michelangelo, as Heath Wilson has pointed out, very slowly acquired the sense of proportion on which technical architecture depends. His early sketches only show a feeling for mass and picturesque effect, and a strong inclination to subordinate the building to sculpture.
It may be questioned who were the four Medici for whom these tombs were intended. Cambi, in a passage quoted above, writing at the end of March 1520(?), says that two were raised for Giuliano, Duke of Nemours, and Lorenzo, Duke of Urbino, and that the Cardinal meant one to be for himself. The fourth he does not speak about. It has been conjectured that Lorenzo the Magnificent and his brother Giuliano, fathers respectively of Leo and of Clement, were to occupy two of the sarcophagi; and also, with greater probability, that the two Popes, Leo and Clement, were associated with the Dukes.
Before 1524 the scheme expanded, and settled into a more definite shape. The sarcophagi were to support statue-portraits of the Dukes and Popes, with Lorenzo the Magnificent and his brother Giuliano. At their base, upon the ground, were to repose six rivers, two for each tomb, showing that each sepulchre would have held two figures. The rivers were perhaps Arno, Tiber, Metauro, Po, Taro, and Ticino. This we gather from a letter written to Michelangelo on the 23rd of May in that year. Michelangelo made designs to meet this plan, but whether the tombs were still detached from the wall does not appear. Standing inside the sacristy, it seems impossible that six statue-portraits and six river-gods on anything like a grand scale could have been crowded into the space, especially when we remember that there was to be an altar, with other objects described as ornaments—"gli altri ornamenti." Probably the Madonna and Child, with SS. Cosimo and Damiano, now extant in the chapel, formed an integral part of the successive schemes.
One thing is certain, that the notion of placing the tombs in the middle of the sacristy was soon abandoned. All the marble panelling, pilasters, niches, and so forth, which at present clothe the walls and dominate the architectural effect, are clearly planned for mural monuments. A rude sketch preserved in the Uffizi throws some light upon the intermediate stages of the scheme. It is incomplete, and was not finally adopted; but we see in it one of the four sides of the chapel, divided vertically above into three compartments, the middle being occupied by a Madonna, the two at the sides filled in with bas-reliefs. At the base, on sarcophagi or cassoni, recline two nude male figures. The space between these and the upper compartments seems to have been reserved for allegorical figures, since a colossal naked boy, ludicrously out of scale with the architecture and the recumbent figures, has been hastily sketched in. In architectural proportion and sculpturesque conception this design is very poor. It has the merit, however, of indicating a moment in the evolution of the project when the mural scheme had been adopted. The decorative details which surmount the composition confirm the feeling every one must have, that, in their present state, the architecture of the Medicean monuments remains imperfect.
In this process of endeavouring to trace the development of Michelangelo's ideas for the sacristy, seven original drawings at the British Museum are of the greatest importance. They may be divided into three groups. One sketch seems to belong to the period when the tombs were meant to be placed in the centre of the chapel. It shows a single facet of the monument, with two sarcophagi placed side by side and seated figures at the angles. Five are variations upon the mural scheme, which was eventually adopted. They differ considerably in details, proving what trouble the designer took to combine a large number of figures in a single plan. He clearly intended at some time to range the Medicean statues in pairs, and studied several types of curve for their sepulchral urns. The feature common to all of them is a niche, of door or window shape, with a powerfully indented architrave. Reminiscences of the design for the tomb of Julius are not infrequent; and it may be remarked, as throwing a side-light upon that irrecoverable project of his earlier manhood, that the figures posed upon the various spaces of architecture differ in their scale. Two belonging to this series are of especial interest, since we learn from them how he thought of introducing the rivers at the basement of the composition. It seems that he hesitated long about the employment of circular spaces in the framework of the marble panelling. These were finally rejected. One of the finest and most comprehensive of the drawings I am now describing contains a rough draft of a curved sarcophagus, with an allegorical figure reclining upon it, indicating the first conception of the Dawn. Another, blurred and indistinct, with clumsy architectural environment, exhibits two of these allegories, arranged much as we now see them at S. Lorenzo. A river-god, recumbent beneath the feet of a female statue, carries the eye down to the ground, and enables us to comprehend how these subordinate figures were wrought into the complex harmony of flowing lines he had imagined. The seventh study differs in conception from the rest; it stands alone. There are four handlings of what begins like a huge portal, and is gradually elaborated into an architectural scheme containing three great niches for statuary. It is powerful and simple in design, governed by semicircular arches—a feature which is absent from the rest.
All these drawings are indubitably by the hand of Michelangelo, and must be reckoned among his first free efforts to construct a working plan. The Albertina Collection at Vienna yields us an elaborate design for the sacristy, which appears to have been worked up from some of the rougher sketches. It is executed in pen, shaded with bistre, and belongs to what I have ventured to describe as office work. It may have been prepared for the inspection of Leo and the Cardinal. Here we have the sarcophagi in pairs, recumbent figures stretched upon a shallow curve inverted, colossal orders of a bastard Ionic type, a great central niche framing a seated Madonna, two male figures in side niches, suggestive of Giuliano and Lorenzo as they were at last conceived, four allegorical statues, and, to crown the whole structure, candelabra of a peculiar shape, with a central round, supported by two naked genii. It is difficult, as I have before observed, to be sure how much of the drawings executed in this way can be ascribed with safety to Michelangelo himself. They are carefully outlined, with the precision of a working architect; but the sculptural details bear the aspect of what may be termed a generic Florentine style of draughtsmanship.
Two important letters from Michelangelo to Fattucci, written in October 1525 and April 1526, show that he had then abandoned the original scheme, and adopted one which was all but carried into effect. "I am working as hard as I can, and in fifteen days I shall begin the other captain. Afterwards the only important things left will be the four rivers. The four statues on the sarcophagi, the four figures on the ground which are the rivers, the two captains, and Our Lady, who is to be placed upon the tomb at the head of the chapel; these are what I mean to do with my own hand. Of these I have begun six; and I have good hope of finishing them in due time, and carrying the others forward in part, which do not signify so much." The six he had begun are clearly the Dukes and their attendant figures of Day, Night, Dawn, Evening. The Madonna, one of his noblest works, came within a short distance of completion. SS. Cosimo and Damiano passed into the hands of Montelupo and Montorsoli. Of the four rivers we have only fragments in the shape of some exquisite little models. Where they could have been conveniently placed is difficult to imagine; possibly they were abandoned from a feeling that the chapel would be overcrowded.
