On Tuesday 31 May 2022, a technical meeting of the partners of the PROTEAS project took place in Athens, at the conservation workshops of the National Gallery – Alexandros Soutsos Museum (ΕPMAS) at the National Glyptotheque, in Goudi. In this space, the work “30 March 1814” by Muller Charles-Louis-Lucien was placed in a horizontal position, and was to be conserved with the help of a wheeled bridge, which allowed the conservator or the student of the work to approach the painting in its entirety. As part of the meeting, exploratory shots were taken using the bridge with the SWIR camera from the Institute of Electronic Structure and Laser of FORTH.
