June 7 Napoleon appointed Eugene de Beauharnais Viceroy of the Kingdom of Italy, and three days later left Milan with Josephine. In all the principal cities of the Empire his coronation had been celebrated by public rejoicings. Murat had given a ball at his castle of Neuilly, about which the _Journal des Debats_ had said: "At the same moment when the arts of ingenious Italy were displaying all their marvels under the eyes of Their Majesties, French gallantry and gaiety were rendering similar homage to the happy reign which had recalled them from a long exile." Aix-la-Chapelle inaugurated the statue of the great Carlovingian Emperor amid salvos of artillery and the applause of the Germanic populace, who saluted at the same time the names of Charlemagne and of Napoleon. XIV. THE FESTIVITIES AT GENOA. The Italian journey closed as brilliantly as it began. After leaving Milan, Napoleon approached the frontiers of Austria, against which he was to fight before the end of the year, visiting the celebrated quadrilateral, consisting of the four fortified towns: Mantua, Peschiera, Verona, and Legnago. He was present at a mimic representation of the battle of Castiglione, in which twenty-five thousand men took part on the field upon which that battle had been fought; then he went to Bologna, where the charms of his conversation were highly appreciated by the learned professors of its university. While he was there a deputation from Lucca visited him, asking him to take that little country under his protection. He gave it for Prince and Princess, his brother-in-law, Felix Bacciocchi, and his sister Elisa, to whom he had already entrusted the Duchy of Piombino. Lucca was thus elevated to a hereditary principality, a dependent of the French Empire, which should revert to the French crown in case the male line of the Bacciocchi should become extinct. It was a sort of revival of the old Germanic fiefs. Evidently the memory of Charlemagne continually filled Napoleon's thoughts. Elisa thenceforth bore the title of Princess of Lucca and of Piombino. She was a well educated and able woman, of marked intelligence and strong will. M. de Talleyrand used to call her "the Semiramis of Lucca." After Bologna, Napoleon visited Modena, Parma, and Piacenza. The cities he passed through rivalled one another in flattery. They voted him medals, statues, and even a temple, which, however, the demi-god declined.
