"Oberto," he was willing to produce it under certain conditions. These were agreed to eagerly, and on the evening of Nov. 17, 1839, "Oberto" was performed for the first time. The work, which is little else than a reflection of Bellini, was well received and was performed several times. Among the changes he had been called on to make in the score before it was finally accepted by the _impresario_, Signor Bartolomeo Merelli, was the introduction of a quartet which was one of the most successful pieces in the opera. Later, the composer achieved other and still greater successes with opera quartets. [Illustration: VERDI'S BIRTHPLACE IN RONCOLE.] The favor with which "Oberto" had been received induced Merelli to engage Verdi to write three operas, to be played either in Milan or Vienna. Eight months' time was given in which to compose each opera, and the price that Verdi was to receive for each was 4,000 livres ($670.00), the profits of the copyright to be divided between composer and manager. Verdi agreed to everything, and Merelli commissioned the poet Rossi to write a libretto for the composer, "Il Proscritto" being the result. Verdi did not like the book, and had scarcely reconciled himself to set it to music when Merelli suddenly demanded a comic opera from him, whereupon Verdi began to compose "Un Giorno di Regno." Then disaster after disaster crowded on him. His two children died suddenly within a few days of each other, and his wife also died after of inflammation of the brain. Three coffins passed out of his house in three months, and he was left without a family. In the midst of this appalling affliction he was obliged to finish his comic opera. It was completed and was a dead failure, only one performance having been accorded it. What could be expected from a comic opera written under such terribly tragic conditions? Naturally, Verdi lost heart, and for the moment discouraged by the failure of his opera, resolved to compose no more. Merelli remonstrated with him, but Verdi was inexorable; and, therefore, the manager cancelled their contract. Later, Verdi and Merelli met again by chance, and the latter, after vainly urging the composer to resume his art, thrust a libretto on him and hastened away. It was the book of "Nabucco." On reaching home Verdi angrily threw the libretto on his writing-table, determined to have nothing to do with it; but his eye, falling on the open page, was attracted by a certain line which he read, and then he was impelled to read page after page and was much impressed by the poem. The result was, that after many struggles with himself the score was completed, and taken to the now triumphant Merelli. The parts were copied out, and at the end of February, 1842, the first rehearsal took place; and on March 9, twelve days later, the first performance was given. The work was an overwhelming success. With this opera, and when he was twenty-nine years old, Verdi's career as a composer began in earnest.
