San Domenico in Pistoia, from survery some theory about the draw between town and monument

Abstract

The planimetric study of the historical city of Pi-stoia allows you to read the city as a drawing set. The rules of the draw create precise geometries, binding measures and Pythagorean triples, throu-gh the “fiorentina arm”, the unit which was pro-bably used at that time. Within this design, the church of San Domenico serves as the key point. Therefore a rigorous survey was conducted, using direct and indirect systems. The survey and study of the design of the city, through measurement and geometry, have allo-wed to understand the design method used by masters of the time. In that way, it has been pos-sible to access to knowledge of data otherwise inaccessible and get the reading of the hidden measures of the project and invisible geometric genesis.
