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 (OPMAS) 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, using the bridge, a preliminary photographic documentation of the project was carried out by the Computer Vision and Robotics Laboratory of the Institute of Computer Science of FORTH.
