Although he was still in the prime of youth, Paganini knew of nothing but success and profit, when, during one of those hallucinations to which all great artists are subject, the Violin lost its attractions in his eyes. A lady of rank having fallen desperately in love with him, and the feeling being reciprocated, he withdrew with her to an estate she possessed in Tuscany.[D] This lady played the Guitar, and Paganini imbibed a taste for that instrument, and applied himself as sedulously to its practice as he had formerly done with the Violin. He soon discovered new resources, which he imparted to his friend; and during a period of three years, he devoted all the energies of his mind to its study, and to agricultural pursuits, for which the lady’s estate afforded him ample opportunities. It was at this period he wrote his two sonatas for Guitar and Violin, which form his second and third works. Love cools with time in a castle as in a cottage. Paganini discovered this; all his former penchant for the Violin returned, and he decided on resuming his travels. On his return to Genoa, in 1804, he occupied himself solely with composition, and wrote here his fourth work which consists of four grand quartetts for Violin, Viol, Guitar, and Violoncello; and bravura variations for Violin, on an original theme, with Guitar accompaniment, which forms his fifth work. It appears too, that at this period he gave instruction on the Violin to Catarina Calcagno,[E] born at Genoa, in 1797, who, at the age of fifteen, astounded Italy by the boldness of her style. All traces of her seem lost after 1816. Towards the middle of 1805, Paganini left Genoa, to undertake a new tour in Italy. The first town he visited was Lucca, the scene of his first successes. Here he again created so great a sensation by a concerto he performed at a nocturnal festival in a convent chapel, that the monks were obliged to leave their stalls, in order to repress the applause which burst forth despite the sanctity of the place. He was then twenty-one years of age. The principality of Lucca and Piombino had been organised in the month of March, of the same year, in favour of the Princess Eliza, sister of Napoleon, and the wife of Prince Bacciochi. The Court had fixed its residence in the town of Lucca. The great reputation of the violinist induced the Princess to offer him the posts of director of her private music, and conductor of the opera orchestra. Notwithstanding his propensity for independence of action, and although the emoluments were scanty, the position pleased him, and he accepted it. The Prince Bacciochi received instruction from him on the Violin. The Princess, who had appreciated the originality of his talent, induced him to extend his discoveries of novel effects upon the instrument. To convince him of the interest he had inspired her with, she granted him the grade of captain in the royal gendarmerie, so that he might be admitted with his brilliant costume to all the
