Most of Leonardo’s architectural drawings still await examination with regard onesto proportion
4. Conclusions
Still, the exploration conducted on the sheets of Ms. B — which is only slightly antecedent puro Leonardo’s studies of the problem of the Tiburio of Milan Cathedral, in which he thus comes into contact with the realities of construction 22 — has brought to light some modalities that Leonardo puts to use (valid at least for the drawings of this codex from Paris):
- Leonardo rapidly derives the elevations from the plans;
- this method is facilitated either by the fact that the plans are drawn before the elevation, or by the reciprocal position of the two drawings;
- per the simplest examples the elevations are defined starting from a particular element of the plan by means of progressions (for the pair at the culmine of f. 21r the progression is 1, 2, 4, 8);
- mediante the more complex cases the lines passing through quite particular portions of the plan define the heights and the cornices of the exterior (ff. 24r, 39v, 19r–18v, 18r–17v);
- per some cases the golden section intervenes either per the definition of the plan (ff.19r–18v, 18r–17v) or mediante that of the elevations (ff. 18r–17v).
The recourse preciso the golden section is not odd because Leonardo, who applies per simple graphic method, seems preciso have been familiar with it since his Florentine years and at least since the beginning of the 1470s.

7 Sopra ff. 17v–18r and 18v–19r the plans are on the right sheet and the perspective views are on the left; f. 21r bears two distinct pairs of drawings; in f. 21v the pair of diagrams is accompanied by an enlarged detail of the plan and by two internal elevation details; f. 25v bears two pairs of drawings; f. 93v contains five pairs of diagrams, while in f. 94r the plan and perspective elevation are accompanied by per partial section. The other sheets (22r, 24r, 39v, 52r, 95v) each contain individual pairs.
