17 Before Michelangelo had the existing wooden model made, he produced a new design and then entered into collaboration with Baccio d'Agnolo, who was to direct construction work, leaving Michelangelo to produce façade sculptures. Soon afterwards, Baccio produced a model of their joint scheme, although this was then dismissed by Michelangelo. See Wallace, Michelangelo at San Lorenzo, pp. 9–11.

18 De Tolnay, Charles, Corpus dei disegni di Michelangelo, 4 vols (Novara, 1975–80)Google Scholar, IV, ff. 501r–510r. Some of the sketches Michelangelo made for the façade's marble blocks have also survived, but their fragmentary and isolated nature makes their study largely irrelevant to this aspect of the commission; see De Tolnay, Corpus, III, ff. 441r–468v, 487r–v.

19 Florence, Casa Buonarroti [hereafter CB] 51A. Scholars have based their varied interpretations on Michelangelo's inscription of la parete beside a silhouette of the façade in either elevation or profile, and on his inclusion of an irregular toothed shape drawn on the bottom-right corner of the sheet, which read as the projecting strips of masonry on the basilica's frontal wall. Elam interprets CB 51A, with reservations, as proof that a veneer façade was planned; see Elam, ‘Drawings as Documents’, p. 109. For a narthex interpretation, see Maurer, Michelangelo: Die Architekturzeichnungen, pp. 192–93.

20 The three folios in question are Florence, Archivio Buonarroti [hereafter AB] I, 157, f. 282r (De Tolnay, Corpus, IV, 502r); CB 113A r–v (Corpus, IV, 503r–v); and AB I, 158, f. 282r (Corpus, IV, 507r). The ground plans Michelangelo drew on CB 100A are omitted from this grouping due to their lack of a clear connection with the project, despite Satzinger's claim that the edge of the frontal wall is discernible; see Satzinger, Michelangelo und die Fassade, pp. 55, 101, fig. 73E.

21 Three of the plans (two on CB 113A v and one on AB I, 157, f. 280r) show the façade in an earlier design stage. Another (AB I, 158, f. 282r) shows the façade and church in outline but lacks any detail to indicate how the two would have been attached.

22 De Tolnay, Corpus, IV, p. 41 and f. 503r; Millon and Smyth, Michelangelo Architect, pp. 45–47. Elam's association of the plan on CB 113A r with foundation arches is questionable. It is the two ground plans Michelangelo drew on the verso of the sheet that are usually associated with the foundations, not the large plan on the recto, and Elam may have accidentally confused the plans or mistakenly identified the verso as the recto; see Elam, ‘Drawings as Documents’, pp. 104, 113, n. 41.

61 While this might be true, no direct mention is made in these reports of the foundations, only that archaeologists did not locate the marbles that Vasari claimed were buried in front of the church; see ‘Per la piazza di S. Lorenzo’, pp. 59–60; ‘Riordinamento della piazza di S. Lorenzo’, pp. 280–81. It is conceivable, however, that the foundations were overlooked during the work, and are thus still in existence.

62 This reconstruction uses the generally accepted scale of 1:13.33 for the model. See Ruschi, ‘Modello ligneo per la facciata di San Lorenzo a Firenze’, pp. 616–17. Based on this scale, the new façade's width (37.99 m) would have been approximately 6 m greater than that of the church (31.90 m). Its left return — including its projecting elements — would have extended about 3 m beyond the nave's southern side wall, positioning it directly in front of the cloister's andito. A space of approximately 1 m, then, would have remained between the façade's return and the Scuola dei Chierici, which stands over 4 m from the edge of the church's front wall (4.44 m; the width of the cloister's andito). The measurements of the church's width and cloister's andito are my own.
