This course provides information on the essential basis of Christian and medieval archeology, either from a historical point of view of this discipline or from a methodological point of view, presenting the development of research themes, results and methodological problems, including the reading of some archaeological contexts.
2 credits
The course aims to provide the knowledge and skills necessary to consciously apply the language of design, aimed at analyzing, understanding, relieving and communicating on the morphology of the paintings artifacts, the wooden artifacts and multi-material artifacts. Part of the course is dedicated to the documentation and cataloging of cultural heritage as a first approach to knowledge. The course aims to provide, on the one hand, a basic understanding of the historical and scientific foundations of the encoded methods of graphic representation that allows you to read the geometric structure in the works of figurative art, and on the other hand, the theoretical and practical tools for analyzing representation of artifacts of a different nature through conventional language.The techniques of representation used will range from the traditional ones of freehand drawing and technical drawing to digitally-supported drawing using specific software, with particular reference to the documentation of restoration sites. The course aims to direct the student in the use of techniques and methods for detection and graphical representation for the purposes of analytical and synthetic problems of graphic documentation for the restoration of cultural heritage.
3 credits
Scientific and technical-commercial criteria for the classification of natural stone materials used in Cultural Heritage. Analysis of most common rock-types, focusing on historical stone materials from local country. Petrographic techniques relevant to Cultural Heritage, with examples of current analytical methods; representation of analytical results. Basic elements for the petrographic description of mortars. Types, mechanisms and causes of deterioration of historic and contemporary natural stone materials. Italian and European standards and recommendations concerning the use and conservation of natural stone materials. Petro-archeometric and conservation case studies.
3 credits
This course aims to provide knowledge on elements of structural chemistry and thermodynamics which are useful for understanding the chemical and physical phenomena of polymeric materials. These bases can be used to improve the choice of materials and interventions to be made in the conservation of cultural heritage.
3 credits
Study, analysis and actualization of the works of C. Brandi, Theory of restoration, Rome 1963: definition of "restoration", the subject-matter of the artwork, the potential unit, time, historical value and aesthetic value, preventive restoration, falsification. Comparison with the theory of restoration of G. Urbani. . History of restoration from the origins to the 18th century: remake, repaint, integration, transfer of frescoes to canvas, revolutionary vandalism, requisitions and refunds.
3 credits
The first part of the course will focus on the following topics:
- Definition, methods and areas of museology;
- History, identity and aims of the museum from the studio and the Wunderkammer to the XIXth models and the different kinds of the contemporary museum;
- Legislation, standards and professions.
In aim of pointing out the relation between museums and the restoration culture, the second part will describe some paradigmatic cases of this interaction within the local context during the XIXth and the XXth Centuries.
