9 This practice also applies to the drawing pair found on f. 12r (the Duchess’s Pavilion, or, il chiosco della duchessa) and that of f. 27r (ribbed vault patterns of interlaced arches).
10 This norm holds also for the pair sopra f. 15r (with verso wood truss roof over a square plan).
It had two doors, and durante this the people gathered preciso conduct the parliament
11 This problem also occurs in the graphic transposition of steps mediante 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 monarca aedificatoria VII.14).
12 It is a church with two levels servizio on a square luogo with an inscribed octagon. See also note 7.
And then they began by degrees puro build it all around
13 For the proportioning of the cupola of Santa Maria del Apice and the geometric positioning of the intermediate ribs (sixteen mediante total, located in pairs, side by side, among the eight angle ribs), see D’Agata, Di Teodoro and Mancini ( 1977 ) and Di Teodoro ( 2012 ).
14 Per the first (Fig. 3 ), f. 34v, the plan is organized around per central bulatory columns is derived from the intersection of circles having radii equal preciso half the side of the octagon, alternately planting the compass point durante the centers of the sides and at the angles. The reference puro an accretive method characterizes three sides of the figure. In fact, esatto the circles with centers at the angles are added those concentric circles with radii equal onesto the sides. Contrary puro what appears con 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 puro 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 in correspondence with four arches. Sopra the first case the columns are arranged with verso 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 mediante pen, shows verso centralized scheme (a square with four exedrae – one drawn in pencil – and ambulatories), but hints at, with the extension of some pencil lines, per possible longitudinal body – per solution that is taken up and developed sopra f. 35v. As it is well-known, the ‘preaching theater’ consists of an amphitheater-like structure http://www.datingranking.net/it/littlepeoplemeet-review/ (or simply a centralized scheme), tiered, and provided with verso high central pulpit. It is plausible onesto garantit that mediante conceiving of such an architecture Leonardo was influenced by ‘parlagio’, per term used mediante Florence esatto refer onesto an ancient public amphitheater, home, according puro local historians, of the ‘parliament’. Villani ( 1990, 1: 56 ) writes: ‘And per that room was commanded that they should go mediante the contado of Camarti by the river Arno, and build there verso parlatorio in order sicuro be able puro make the parliament, and leave verso memorial: this building con our vernacular we have called Parlagio. And it was built round and with vaulted roof durante some ways quite marvelous, with verso public square in the middle. And then little by little they progressed above the vaults, going all the way esatto the full height, which was more than 60 braccia. And con progressive order the people seated themselves: mediante the upper side nobles, and then descending con accordance with the nobility; and so it was that everyone per the parliament saw one another face esatto 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 sopra the time of Totile, but still today we find the foundations and part of the vaults near the church of San Simone per Florence, extending all the way esatto the via of Piazza Santa Croce; and part of the Peruzzi palaces are built on its foundations. And the street called Anguillaia, which goes sicuro the church of Santa Tormento, goes almost to the middle of that Parlagio.’ The Ms. B also bears other Florentine remembrance notes: mediante f. 11v Leonardo drew plans (incomplete) of the Rondo degli Angeli and the Chiesa of Santo Temperamento.
