            which guided the architectural reconstruction. For the
            textural elements, Quixel Megascans, a comprehensive
            library of high-resolution scans, provided the base
            textures. Arabescato marble scans were used to simulate
            marble components, while a template of reclaimed wood
            emulated the wooden flooring, walls, and ceilings. The
            intricate details, such as room drapery, drew inspiration
            from Samuel F.B. Morse (1791 – 1872) and his  Gallery
            of the Louvre (1831 – 1833) (Figure 1), adopting altered
            carpet scans to resemble the depicted drapery, with specific
            adjustments to color and texture parameters to achieve
            historical fidelity.
              For the virtual environment, diverse references and
            templates were used to replicate architectural and decorative   Figure 1. Samuel F.B. Morse, Gallery of the Louvre, 1831 – 1833, oil on

            A megascan representing arabescato marble (Figure 2, top
            right) served as the foundation for replicating the marble
            elements observed. The flooring, walls, and ceilings of
            the Salon, known to be wooden, found their emulation
            through a template of reclaimed wood. Considering Pietro
            Antonion Martini (1738 – 1797), entitled View of the Salon
            of 1785 (Figure 3), which was the primary reference for
            laying out and constructing the scene, the discernibility of
            room drapery or the intricate decorative details described
            in the Livret remained ambiguous.  Drawing inspiration

            drapery adorning the  walls,  a  scan  first  representing  a
            carpet  underwent  alterations  to  emulate  the  color  and
