About one year later, or, to be more exact, on the evening of Feb. 11, 1843, "I Lombardi" was produced, and again success crowned the composer's efforts. It was a great advance on its predecessor in point of style and individuality, and is still performed. Commissions now began to pour in on Verdi, and his name was becoming known beyond the borders of his native land. Managers sought eagerly for scores from him, and the _impresario_ of the Fenice Theatre in Venice obtained his next work, which was "Ernani." It was first performed March 9, 1844, and excited immense enthusiasm; and within the nine months after it appeared it was performed in no less than fifteen opera houses, making later a tour of the world, and remaining for many years one of the most popular of modern operas. In November of the same year "I Due Foscari" was brought out at the Argentina Theatre in Rome, and though it had a fair success, it did not increase Verdi's reputation. He was now writing with great rapidity, and in three months "Giovanna d'Arco" was played at La Scala. It did not become popular and has fallen into oblivion, its overture alone surviving. Six months after "Alzira" was produced at La Scala, and again the composer failed to repeat the triumph he had won in "Ernani." His next opera, "Attila," was written for the Fenice, and on the evening of March 17, 1846, it excited a furore equal to that which attended his "Ernani" at the same house. Then came "Macbeth" one year later, which was a failure owing to the absence of a part for a tenor singer.
