Drawings, models, architecture, art history: historical study and virtual restitution In the era of digital humanities

Alexander Neuwahl participated for ArtesMechanicae in the seminar organized by the PhD School of Architecture in Florence, from the Sorbonne and the École Pratique des Hautes Études in Paris, the CNRS of Marseille and the Leonardian Library of Vinci. After Paris in November 2015, Marseille in June 2016, and Bologna on 12 and the 13 September 2016, the seminar was the last stage of a common path of several researchers from European universities which focused on the topic of reading, of the study, of the interpretation – and therefore of the 'communication' of contents – of architectural drawings using different computer techniques, particularly those based on 3D models, with a main focus on the Italian Renaissance but not only. Based on a dialogue between architectural historians and specialists in more innovative technologies, modeling issues, restitution and use via telematic and IT interfaces were at the center of this project. While the first seminar (Paris) sought to highlight the specific skills underlying this interdisciplinary work, the second (Marseille) focused on significant methodological issues on which to develop new approaches within a framework of common and shared standards; and again, in the third appointment (Bologna) specific cases were analysed, focused on the Renaissance design-new information technologies dyad, with a view to highlighting original experiences and possible points of convergence. Starting from the numerous experiences carried out around Leonardo da Vinci's graphic corpus, with this further stage it proposed a comparison between the different 'knowledge' that has been involved for some time on these topics and at the same time create a moment of meeting between doctoral students – of different backgrounds and origins – and the professionals who deal with the history of art and architecture, in digital humanities, 3D Reconstruction, interface design, experience design, museology, augmented reality. This fourth seminar, held over two days in Florence – DIDA and to Win – Leonardiana Library, it constituted an opportunity for reflection on the issues of creation and use of digital content, both at the level of the 'construction' process, both at the level of museum design. From this point of view, the experiences of the Leonardo Museum in Vinci and the CNRS in Marseille are of great interest and express case studies of absolute importance and originality in the European panorama.
