Venice Time Machine

Résumé

La Venice Time Machine est un projet de recherche international dirigé par l’École Polytechnique Fédérale de Lausanne (EPFL) et l’Université Ca' Foscari de Venise, débuté en 2012, et visant à développer un modèle spatio-temporel de la ville de Venise en créer une archive ouverte numérique du patrimoine culturel. Le projet cherche à documenter et tracer quantitativement et qualitativement les aspects urbanistiques et architecturaux, les flux commerciaux et culturels, ainsi que les données démographiques sur une période de plus de 1000 ans. Sa réalisation représenterait la plus grande base de données de documents vénitiens jamais créée. Le projet est un exemple caractéristique du nouveau champ de recherche que constitue les humanités digitales. Le projet a été largement salué par la critique, ce qui a conduit au dépôt d’un projet européen FET Flagships, en avril 2016. Le projet Europe Time Machine parviendra finaliste de la compétition avant que ce type de financement de recherche ne s

Handwritten characters in administrative antique documents from three centuries have been detected using different synchrotron X-ray imaging techniques. Heavy elements in ancient inks, present even for everyday administrative manuscripts as shown by X-ray fluorescence spectra, produce attenuation contrast. In most cases the image quality is good enough for tomography reconstruction in view of future applications to virtual page-by-page `reading'. When attenuation is too low, differential phase contrast imaging can reveal the characters from refractive index effects. The results are potentially important for new information harvesting strategies, for example from the huge Archivio di Stato collection, objective of the Venice Time Machine project

X-ray spectrometry and imaging for ancient administrative handwritten documents

Fauzia Albertin, Frédéric Kaplan, Giorgio Margaritondo, Marco Stampanoni

‘Venice Time Machine’ is an international program whose objective is transforming the ‘Archivio di Stato’ – 80 km of archival records documenting every aspect of 1000 years of Venetian history – into an open-access digital information bank. Our study is part of this project: We are exploring new, faster, and safer ways to digitalize manuscripts, without opening them, using X-ray tomography. A fundamental issue is the chemistry of the inks used for administrative documents: Contrary to pieces of high artistic or historical value, for such items, the composition is scarcely documented. We used X-ray fluorescence to investigate the inks of four Italian ordinary handwritten documents from the 15th to the 17th century. The results were correlated to X-ray images acquired with different techniques. In most cases, iron detected in the ‘iron gall’ inks produces image absorption contrast suitable for tomography reconstruction, allowing computer extraction of handwriting information from sets of projections. When absorption is too low, differential phase contrast imaging can reveal the characters from the substrate morphology
