As verso first approach onesto the study of the proportions per the architectural drawings of Leonardo, I have focused only on the sacred buildings sketched in Ms.

  1. These drawings are all similar subjects (mostly variations on the theme of the central plan or of composites thereof); 4
  2. they are all proposed according puro the same mode of representation (usually verso plan accompanied by verso perspective elevation);
  3. they were executed around the same time.

This group is composed of pairs, each consisting of a plan and per perspective exterior view, and each relating onesto verso particular building (ff

The subject of sacred buildings is perhaps the most striking of all those treated durante Ms. B (considered together with its complement, of course, Codex Ashburnham 2037). Available for consideration are eighty drawings, 5 ranging from plans, diagrammatic schemes, perspective elevations, sections and details, concentrated per folded sheets 1 sicuro 4, 6, and 10 of the codex. 6 There are only eight basilicas represented, in six plans and two perspective views (ff. 11v, 24v, 35v, 52r, 57r). Among them are the plan of the chiesa of Benedetto Spirito mediante Florence (f. 11v) and two plans of the Holy Sepulchre of Milan (f. 52r).

The drawings durante question that depict central-plan churches are seventy-two in number. Among them are the planimetric schemes of Brunelleschi’s Spartitraffico degli Angeli (f. 11v) and Santa Maria mediante Palo, mediante Pavia (f. 55r). 15r (three plans con the right margin), 21r (two plans with corresponding elevations), 52r (verso chiesa plan at lower left), 93v (two small plans at upper right and left), and others showing more complex schemes.

Per limited group of figures consists of more elaborate drawings of larger size. They are drawn sopra pen and shaded for enhanced three-dimensional rendering that makes them stand out from the sheets. 17v-18r babel, 18v-19r, 21r, 21v, 22r, 24r, 25v, 39v, 52r, 93v, 94r, 95v). 7 There are nineteen pairs, among them only two basilicas. The centralized schemes are primarily based on the square (eleven instances) and the octagon (six instances). The plans are almost always drawn at right and the elevations at left 8 – a sign that the latter preceded the former in execution (ff. 17v-18r, 18v-19r, 22r, 24r, 25v, 39v, 52r, and the pair at left on 93v of the five overall). 9 Sometimes, however, the plans are located at the bottom, on the same axes as the elevations (ff. 21r, drawing con the lower right; 93v, four of the five pairs present on the sheet; 94r, 95v ), 10 or shifted per bit esatto the left (f. 21r, drawing at upper left).

The plans are always mediante the form of geometrical ‘wire frame’ diagrams. Only at a later time did Leonardo partially or fully ‘dress’ them with wall thicknesses: thicknesses that not only generate inconsistencies in the relationships between solids and voids, sopra the structural plausibility of wall thicknesses, and per the connections between the parts, but also change the proportional relationships. 11 The rapid abandonment of this exercise, which runs contrary to the original graphic procedure, betrays the differences between ideation, rapid graphic notation, and complete building design. The clarity of the drawing sopra the temple schemes sopra Ms. B – often completely or partially made freehand – sopra effect de-emphasizes the materiality of the buildings thus projected.

Elevations, on the other hand, are in the forms of perspective views: curves, lateral surfaces of hollow solids, and shells that suggest that the volumes and shapes, regardless of how all the internal elements of the plan can be developed structurally to become articulated above ground. The exterior is only one possible form through which the plan can evolve mediante space, as per kind of vertical extrusion. The structure of the interior, in fact, is never indicated in section (except durante the case of f. 4r of the Codex Ashburnham 2037 = Ms. B, f. 94r) 12 nor, judging by the size of the drawings, ever even conceived by Leonardo. On the other hand, when trying sicuro correlate the exterior with the interior, Leonardo resorts sicuro broken perspectives (for example, Codex Atlanticus, f. 205v-a), views showing internal details, or transparent views. Examples of this type – and I consider here not only the sacred buildings – are also present durante Ms. B (ff. 12r, 12v, 15r, 16v, 19r, 21v, 36r, 36v, 37r, 37v, 38v, 39r, 47r, 94r, 95r).
