his sympathy with the more modern school of opera that existed outside of Italy; and in this work he essayed a more declamatory recitative, a deeper regard for tone-color, and a more serious devotion to the dramatic sentiment of the scene and action, and less to the mere formal aria. In other words, Verdi became, to some extent, a revolutionist in his art, and was the first Italian master to recognize what was going on in the world of opera beyond the confines of his own country. The work in which this cry of progress was sounded met with complete failure, and for a time he returned to the old order of things, or else approached the new with faint-heartedness. When, after four years' silence, he was heard again, he was boldly and unequivocally an advocate of the new movement, as "Aïda" amply testifies. Here he abandons, for good and all, the conventional forms to which he had so long adhered. He has considered his libretto as a whole, and not as so many opportunities for tune-making; he has attempted to maintain a proper and uniform local color--has tried to create the impression of an unbroken and self-consistent dramatic entirety; he has essayed to impart as much interest to the recitatives, and to the more declamatory aspects of his score, as to the more purely melodious. The melody flows on with the familiar fluency, but it is tempered by dignity. The orchestra looms into primary importance as part of a logical whole, instead of remaining the mere accompaniment, more or less artistic, that it is in the composer's other scores. It is Verdi still, but a Verdi matured in style and fully ripened in artistic judgment,--a Verdi thoroughly awake, for the first time, to the fact that the horizon of art is bounded only by the height from which it is viewed. [Illustration: CARICATURE OF VERDI BY DANTAN. From the Carnavalet Museum, Paris.] In "Aïda" there is little that can be detached from its stage surroundings without loss of effect. That Verdi was satisfied with the results achieved by him in this opera is evidenced by his revision and rewriting of "Simon Boccanegra," in which the earlier melodies are retained, but in which the dramatic portions of the score are deepened and intensified, and made even more impressive than were the like features in the score of "Aïda." His "Othello," if not a still further step in advance, maintains to the full the position now assumed by the master. It is interesting to compare his treatment of the tragedy with that of his predecessor, Rossini. In all that pertains to dignity, sympathy with the spirit of the poem, seriousness of style and sincerity of art, the advantage lies wholly with the modern composer. Rossini's "Othello," however, emphasized an epoch in serious opera, for it is the first opera written throughout in _recitativo strumento_ to the exclusion of the customary _recitativo secco_.
