Abstract
The resounding discovery of part of Notre-Dame's medieval rood screen at the crossroads of the Notre-Dame transept in 2022, as part of Inrap's preventive excavations, the joint work of restorers and research engineers on the cathedral's post-fire remains, and the program to restore and analyze the sculpted elements of the edifice preserved at the Musée de Cluny, represent a remarkable breeding ground for new discoveries. The skills of the various contributors (geology, polychromy, restoration, archaeology, art history) have renewed our knowledge of the material context in which these sculptures were created. Whether it's the supply of stone, the polychromy of the sculptures, or the dating possibilities offered by carbon 14analysesof lead white, the interdisciplinary approach of this veritable interdisciplinary laboratory brought together around the cathedral and the exhibition offers new information and rich prospects for future research.
