03 Jul Most of Leonardo’s architectural drawings still await examination with regard sicuro proportion
4. Conclusions
Still, the exploration conducted on the sheets of Ms. B - which is only slightly antecedent esatto 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 preciso light some modalities that Leonardo puts puro 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;
- sopra the simplest examples the elevations are defined starting from a particular element of the plan by means of progressions (for the pair at the sommita of f. 21r the progression is 1, 2, 4, 8);
- sopra 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);
- con some cases the golden section intervenes either per the definition of the plan (ff.19r–18v, 18r–17v) or per that of the elevations (ff. 18r–17v).
The recourse esatto the golden section is not odd because Leonardo, who applies a simple graphic method, seems esatto have been familiar with it since his Florentine years and at least since the beginning of the 1470s.
