with stucco depictions of the seasons personified and medals bearing Eberhard Louis's initials. The Queen's Staircase is a mirror of the King's, but the statuary depicts virtues and the ribbonwork above displays Apollo, Artemis, and the four classical elements. Two galleries lead from the stairs to a guardroom decorated by Diego Carlone in 1730 with stucco weapon trophies and fresco. Thouret covered over Carlone's work with Neoclassical ornamentation in 1815. The guardroom leads into the Marble Hall (Marmorsaal), the palatial dining hall once used to receive Francis II of Austria and Alexander I of Russia. Thouret began work here in 1813–14 by installing a new, curved ceiling and finished two years later with the Marble Hall's scagliola walls. Pilasters and windows form the lower wall, decorated with stucco garlands and candelabras by Antonio Isopi. Reproductions of the Medusa Rondanini, Hermes Ludovisi, and the Medici Vase are present around the doors. Above the hall is a walkway in the attica, divided by pillars clad with caryatids holding plates and pitchers designed by Johann Heinrich von Dannecker. The ceiling fresco, by Pernaux, is of a partly cloudy blue sky that contains an eagle and four smaller birds that each hoist a chandelier. The roof above the Marble Hall, though curved, has no visible supports. This was achieved by cantilevering its weight upon the entablatures at the top of the walls of the Marble Hall. To the east of the Marble Hall is Queen Charlotte's apartment, originally the suites intended to house Prince Frederick Louis and Princess Henrietta Maria. When Charlotte joined Frederick I in residence at Ludwigsburg in 1798, the separating walls were removed to form one suite. Thouret only made small changes to the queen's suite from 1802 to 1806, principally adding damask to the primary antechamber and to the assembly and audience rooms. Extensive renovations, lasting from 1816 to 1824, came after the queen fully established herself at Ludwigsburg. Charlotte's audience chamber contains her throne, red silk walls, and paintings of Cybele, Minerva, and personified virtues by over the doors and in the lunettes of the mirrors. The adjacent bedroom was remodeled in 1824 with marbled green pilasters and an alcove containing red silk from 1760. The study is unusual for a Neoclassical interior because of its large mirrors. Finally, there is the summer study and the queen's library, remodeled in 1818 with blue damask and Rococo overdoors that carry
