Subject of this thesis are six maps preserved at the State Archives of Modena, in the collection of Mappario Estense. This fund (Vaccari, 2006) was created in the nineteenth century artificially picking the best map products or examples collected during the Duchy of the Este family is in Ferrara (12081598) and at Modena and Reggio Emilia from 1452 to 1796, the year in which the Este government broke off to be reconquered from 1814 to 1859 with the family branch of the Habsburg-Este. All cartographic documents that make up the Mappario Este are unfortunately devoid of any useful information to reconstruct the historical context and the reasons that justified the drafting. The thesis project, in particular, has been designed especially to the determination of the materials used for the realization of some of these maps, through non-invasive analyzes of the diagnostic type, to try to understand how these documents were made, which had a purpose practical, in the space of time that goes from the fifteenth to the eighteenth century AD.
The paper, therefore, is divided into two parts: the first in which provides general information about the exhibition which includes the artistic and historical maps and further (in particular on the map of the "Croce Arcana" and "Map of Contention" ) a detailed description regarding the problems of degradation, conservation and restoration of materials involved (problems that they face every day in the Laboratory of Bookbinding and Archive restoration of State, with whom I have also done my internship). The second part, however, as the results of non-invasive diagnostic tests (Raman, Xrf and multispectral surveys) carried out in collaboration with the University of Modena and Reggio Emilia, in particular with prof. Pietro Baraldi, Paolo Zannini and Andrea Rossi.
It was decided to choose precisely these maps for their particular polychrome and, therefore, suitable to a later stage of diagnostic analysis on them carried out, the objective of determining the materials and the palette of pigments of those who realized these documents. In particular, for their beauty and peculiarity, they have been studied in more depth maps N° 20 and 23. As for the diagnostic analysis, have been performed on documents Raman investigations, Xrf and those multispectral (UV and IR), with the aim of identifying the pigments, the materials and techniques of execution.
