Un nuovo concetto di valorizzazione: i risultati della diagnostica a Venezia nelle opere di Giorgione, Sebastiano del Piombo e Tiziano

The research deals with the diagnostic materials coming from Giorgione, Sebastiano del Piombo and Titian paintings collected in the archives of the Superintendency of Fine Arts and State Museums of Venice and the adoption of an interdisciplinary approach to the existing bibliographic and archive materials and documentation enriches and enhances the conservation history of each work of art. Furthermore the research individuates in SICaR (Sistema Informatico per la Catalogazione dei cantieri di Restauro, Italian Ministry of Culture) a new instrument for understanding and promoting the information acquired on painting materials and techniques and demonstrates its importance both for new insights into the history of art and for museum communication. The proposal of a new model to organise and share scientific data directly online, allows a kind of participant observation in the workshops of the artists of the past: we can detect stages of the work otherwise unknown and highlight connections between paintings created in the same cultural context which are now in different museums. Thanks to the new organisation of scientific data, the widespread use of models in the Venetian painting of the XVI Century is proved, as it was during the XV Century. Models are elaborated directly on the support, so that the painter’s “pentimenti” shown by the diagnostic analyses disclose the various steps in the creation of the work of art.
