In the summer of 1808, Paganini obtained leave to travel, and quitted Lucca, never more to return. As the sister of Napoleon had become Grand Duchess of Tuscany, she fixed her residence at Florence, with all her court, and where the great artist retained his position. He went to Leghorn, where, seven years previously, he had met with so much success. He has related, with much humor, a series of tribulations which happened to him upon the occasion of his first concert there. "A nail," he said, "had run into my heel, and I came on limping, at which the audience laughed. At the moment I was about to commence my concerto, the candles of my desk fell out. (Another laugh.) At the end of the first few bars of the solo, my first string broke, which increased the hilarity of the audience; but I played the piece on the three strings—the grins quickly changed into acclamations of applause." This broken string frequently occurred afterward; and Paganini has been accused of using it as a means of success, having previously practiced upon the three strings, pieces which appear to require the use of the first string.

From Leghorn he went to Turin, where Paganini was first attacked with the bowel complaint, which subsequently so debilitated his health, as frequently to cause long interruptions to his travels, and his series of concerts.

Being at Milan in the spring of 1813, he witnessed, at the theatre of La Scala, the ballet of Il noce di Benevento (the Drowned One of Benevento). It was from this ballet Paganini took the theme of his celebrated variations, le Streghe (the Witches), from the air being that to which witches appeared. Here he was again seized with a return of his former malady, and several months elapsed before he could appear in public. It was only on the 29th of October following, he was enabled to give his first concert, exciting a sensation which the journals of Italy and Germany made known to the whole world.

In the month of October, 1814, he went to Bologna, when he saw Rossini for the first time, and commenced a friendship which became strengthened at Rome in 1817, and at Paris in 1831.

In the year 1817, he arrived at Rome, and found Rossini there busy in producing his Cenerentola. Several concerts he gave here during the Carnival excited the greatest enthusiasm. From this time, Paganini formed the project of leaving Italy to visit the principal cities in Germany and France; and in the year 1819, he arrived at Naples. It is a very remarkable circumstance, that he appeared here in a manner unworthy of his great name; for, instead of giving his first concerts at St. Carlo, he modestly commenced at the theatre of the Fondo.

On his arrival at Naples, Paganini found several artists indisposed toward him. They doubted the reality of the prodigies attributed to him, and awaited a failure. To put his talent to the test, the young composer, Danna, was engaged, recently from the Conservatory, to write a quartet, containing every species of difficulty, convinced that the great violinist would not vanquish them. He was, therefore, invited to a musical re-union, where the piece was immediately given to him to play at first sight. Understanding the snare that was laid for him, he merely glanced at it, and played it as if he had been familiar with it. Amazed and confounded at what they had heard, the highest approbation was awarded to him, and he was proclaimed a miracle.

It was during this sojourn at Naples that Paganini met with one of the most singular adventures of his extraordinary life. An alarming relapse of his malady took place; and, satisfied that any current of air was injurious to him, he took an apartment in the part of the town called Petrajo under Saint Elme; but meeting here that which he most sought to avoid, and his health daily becoming worse, it was reported that he was consumptive. At Naples, the opinion prevails that consumption is contagious. His landlord, alarmed at having in his house one who was supposed to be dying of this malady, had the inhumanity to turn him into the street, with all he possessed. Fortunately, the violoncellist, Ciandelli, the friend of Paganini, happened to be passing, and, incensed at the act of cruelty he was witness to, and which might have proved fatal to the great artist, belabored the barbarian unmercifully with a stick he carried, and then had his friend conveyed to a comfortable lodging, where every attention was paid to him.

Between 1820 and 1828, he visited Milan, Rome, Naples, and Trieste, and on the 2d of March, 1828, he proceeded to Vienna.

On the 29th of March, the first concert of this artist threw the Viennese population into an indescribable paroxysm of enthusiasm. "The first note he played on his Guarneri" (says M. Schilling, in his poetical style, in his Lexique Universel de Musique)—indeed, from his first step into the room—his reputation was decided in Germany. The Vienna journals were unlimited in hyperbolical expressions of admiration; and all admitted his performance to be incomparable. Verses appeared in every publication—medals were struck—the name of Paganini engrossing all; and, as M. Schottky remarks, every thing was à la Paganini. Cooks designated certain productions after him; and any extraordinary stroke of billiards was compared to a bow movement of the artist. His portrait appeared on snuff-boxes and cigar-cases; his bust surmounted the walking-sticks of the fashionable men. After a concert given for the benefit of the poor, the magistrate of Vienna presented to Paganini the large gold medal of St. Salvator, and the emperor conferred upon him the title of virtuoso of his private band.

After an uninterrupted series of triumphs, during three years, the celebrated artist arrived at Paris, and gave his first concert at the Opera, the 9th of March, 1831. His studies for the violin, which had been published there for some time—a species of enigma which had perplexed every violinist—the European fame of the artist—his travels and triumphs—raised the curiosity of the artists and the public. It were impossible to describe the enthusiasm his first concert created—it was universal frenzy. The same enthusiasm prevailed during his entire stay in Paris.
