9 This practice also applies puro the drawing pair found on f. 12r (the Duchess’s Pavilion, or, il pergolato della duchessa) and that of f. 27r (ribbed vault patterns of interlaced arches).

10 This norm holds also for the pair con f. 15r (with per wood login victoria milan truss roof over verso square plan).

It had two doors, and per this the people gathered to conduct the parliament

11 This problem also occurs mediante the graphic transposition of steps sopra Alberti’s De monarca aedificatoria. Consider, for example, the proportions of the three planimetric typologies for basilicas (simple, with causidica, and double-doored) that do not take into account the wall thickness (Alberti, De re aedificatoria VII.14).

12 It is per church with two levels batteria on per square questione with an inscribed octagon. See also note 7.

And then they began by degrees esatto build it all around

13 For the proportioning of the cupola of Santa Maria del Ornamento and the geometric positioning of the intermediate ribs (sixteen in total, located per pairs, side by side, among the eight angle ribs), see D’Agata, Di Teodoro and Mancini ( 1977 ) and Di Teodoro ( 2012 ).

14 Con the first (Fig. 3 ), f. 34v, the plan is organized around a central bulatory columns is derived from the intersection of circles having radii equal sicuro half the side of the octagon, alternately planting the compass point con the centers of the sides and at the angles. The reference esatto an accretive method characterizes three sides of the figure. Per fact, preciso the circles with centers at the angles are added those concentric circles with radii equal esatto the sides. Contrary preciso what appears durante Leonardo’s freehand drawing, these larger circles do not pass through the intersections of the smaller ones. Mediante the second drawing (Fig. 4 ), f. 35r, instead, the columns are identified by the intersections of concentric circles, alternately with radius equal to half the side of the octagon, and with radius equal sicuro the line joining the centerlines of two adjacent sides. The latter circles define the outer perimeter of a centralized building of eight lobes buttressed (or articulated with pilasters), as shown durante the left portion of the drawing, where one wall thickness is called out per correspondence with four arches. Mediante the first case the columns are arranged with a greater regularity (they are two different on-center intercolumniations) than the second (where there are three types of intercolumniations).

15 Leonardo also examines the ‘sportello da predicare’ (preaching theater) per f. 55r of Ms. B (‘theaters for saying mass’) and f. 95r of the same codex (‘place for preaching’). The design of f. 55r, on the other hand, executed con pen, shows per centralized scheme (a square with four exedrae – one drawn in pencil – and ambulatories), but hints at, with the extension of some pencil lines, verso possible longitudinal body – verso solution that is taken up and developed per f. 35v. As it is well-known, the ‘preaching theater’ consists of an amphitheater-like structure (or simply per centralized scheme), tiered, and provided with per high central pulpit. It is plausible to garantis that sopra conceiving of such an architecture Leonardo was influenced by ‘parlagio’, a term used con Florence sicuro refer esatto an ancient public amphitheater, home, according onesto local historians, of the ‘parliament’. Villani ( 1990, 1: 56 ) writes: ‘And durante that room was commanded that they should go per the borgo of Camarti by the river Arno, and build there per parlatorio in order onesto be able onesto make the parliament, and leave per memorial: this building con our vernacular we have called Parlagio. And it was built turno and with vaulted roof sopra some ways quite marvelous, with a public square per the middle. And then little by little they progressed above the vaults, going all the way to the full height, which was more than 60 braccia. And per progressive order the people seated themselves: con the upper side nobles, and then descending durante accordance with the nobility; and so it was that everyone mediante the parliament saw one another face to face. And all could hear clearly that which was spoken; and it contained easily an endless multitude of people; and the correct name for this place was the parlatorio (meeting parlor). This was destroyed mediante the time of Totile, but still today we find the foundations and part of the vaults near the church of San Simone durante Florence, extending all the way puro the start of Agora Santa Affanno; and part of the Peruzzi palaces are built on its foundations. And the street called Anguillaia, which goes esatto the church of Santa Disgrazia, goes almost esatto the middle of that Parlagio.’ The Ms. B also bears other Florentine remembrance notes: in f. 11v Leonardo drew plans (incomplete) of the Spartitraffico degli Angeli and the Chiesa of Benedetto Segno.
