the painting from 1972 to 1976 revealed that assistants only finished some of the lower left figures, while the rest of the painting is by Raphael himself. Rather than send it to France, Cardinal Giulio de' Medici retained the picture. In 1523, he installed it on the high altar in the Blessed Amadeo's church of San Pietro in Montorio, Rome, in a frame which was the work of Giovanni Barile (no longer in existence). Giulio ordered Penni a copy of the Transfiguration to take with him to Naples. The final result with slight differences from the original is preserved in the Prado Museum in Madrid. A mosaic copy of the painting was completed by Stefano Pozzi in St. Peter's Basilica in the Vatican City in 1774. In 1797, during Napoleon Bonaparte's Italian campaign, it was taken to Paris by French troops and installed in the Louvre. Already on 17 June 1794, Napoleon's Committee of Public Instruction had suggested an expert committee accompany the armies to remove important works of art and science for return to Paris. The Louvre, which had been opened to the public in 1793, was a clear destination for the art. On 19 February 1799, Napoleon concluded the Treaty of Tolentino with Pope Pius VI, in which was formalized the confiscation of 100 artistic treasures from the Vatican. Among the most sought after treasures Napoleons agents coveted were the works of Raphael. Jean-Baptiste Wicar, a member of Napoleon's selection committee, was a collector of Raphael's drawings. Baron Antoine-Jean Gros, another member, had been influenced by Raphael. For artists like Jacques-Louis David, and his pupils Girodet and Ingres, Raphael represented the embodiment of French artistic ideals. Consequently, Napoleon's committee seized every available Raphael. To Napoleon, Raphael was simply the greatest of Italian artists and The Transfiguration his greatest work. The painting, along with the Apollo Belvedere, the Laocoön, the Capitoline Brutus and many others, received a triumphal entry into Paris on 27 July 1798, the fourth anniversary of Maximilien de Robespierre's fall. In November 1798, The Transfiguration was on public display in the Grand Salon at the Louvre. As of 4 July 1801, it became the centrepiece of a large Raphael exhibition in the Grande Galerie. More than 20 Raphaels were on display. In 1810, a famous drawing by Benjamin Zix recorded the occasion of Napoleon and Marie Louise's wedding procession through the Grande Galerie, The Transfiguration on
