"La Straniera" cost its authors much trouble, for there were situations which poet and musician could not see and feel alike; but at last their spirits harmonized, and on Feb. 14, 1829, this opera met a magnificent reception at La Scala. A richer, more varied, and deeper talent was there shown than in any preceding work, and the proud Catanians caused an honorary medal to be struck in commemoration of it. Now Parma offered Bellini a remunerative commission, which he accepted, and went thither to prepare his work. He began badly, for he declined the collaboration of a favorite local writer, in order not to separate himself from Romani. The latter's libretto, "Zaira," was poor, and Bellini was not in good vein. All things worked together for ill; so the opera, produced in 1829, was a failure, and only a couple of extracts from it remain. The other operas were doing so well as to console him for this mortification, and he went from city to city to prepare them for presentation. Venice begged something new for La Fenice; and Bellini, reverting to an early admiration for the story of "Romeo and Juliet," accepted from Romani, "I Capuletti ed i Montecchi," which was given in March, 1830, Grisi making one of the cast, and such parts of "Zaira" as were worth saving being wrought into the score. Success attained the height of a popular ovation, and Francis I., of Naples, sent Bellini the medal of Civil Merit, while he, in turn, dedicated his work in grateful terms to his fellow-citizens of Catania. But Milan, jealous of the attentions heaped by other cities upon her favorite composer, insisted on his return. Scarcely had he arrived when he was seized with an intestinal disorder which brought him to death's door. But youth, care, and skill saved him, and he began at once his new score, destined for the Carcano, which had a fine company and repertory, and was fairly rivalling La Scala. This score was "La Sonnambula," the libretto of which Romani had founded on a comedietta by Scribe. Bellini was anxious to excel himself, for the leading singers were none other than Pasta and Rubini. The conditions were favorable, for the fascinating and profitable society of these artists and especially of la Pasta, influenced and stimulated his genius. On March 6, 1831, "La Sonnambula" was produced and began that triumphant success which shows small sign of waning.
