Napoleon III style
The Napoleon III style was a highly eclectic style of architecture and decorative arts, which used elements of many different historical styles,and also made innovative use of modern materials, such as iron frameworks and glass skylights. It flourished during the reign of Emperor Napoleon III in France (1852–1871) and had an important influence on architecture and decoration in the rest of Europe and the United States. Major examples of the style include the Opéra Garnier in Paris by Charles Garnier (1862–71), the Bibliothèque nationale de France. and the Church of Saint Augustine (1860–1871). The architectural style was closely connected with Haussmann's renovation of Paris carried out during the Second Empire; the new buildings, such as the opera, were intended as the focal points of the new boulevards.
Palace of Fontainebleau
Once the monarchy was restored, King Louis XVIII had the gallery completed in a neoclassical style. A new series of the goddess Diana was done by Merry-Joseph Blondel and Abel de Pujol, using the painted frames prepared for Napoleon's cycle. Paintings were also added along the corridor, illustrating the history of the French monarchy, painted in the "Troubador" style of the 1820s and 1830s, painted by a team of the leading academic painters. Beginning in 1853, under Napoleon III, the corridor was turned into a library and most of the paintings were removed, with the exception of a large portrait of Henry IV on horseback by Jean-Baptiste Mauzaisse. The large globe near the entrance of the gallery, placed there in 1861, came from the office of Napoleon in the Tuileries Palace.
