Passing over "Armida," written for the opening of the new San Carlo at Naples, "Adelaida di Borgogna," for the Roman Carnival of 1817, and "Adina," for a Lisbon theatre, we come to a work which is one of Rossini's most solid claims on musical immortality, "Mosé in Egitto," first produced at the San Carlo, Naples, in 1818. In "Mosé," Rossini carried out still further than ever his innovations, the two principal rôles--_Mosé_ and _Faraoni_--being assigned to basses. On the first representation, the crossing of the Red Sea moved the audience to satirical laughter, which disconcerted the otherwise favourable reception of the piece, and entirely spoiled the final effects. The manager was at his wit's end, till Tottola, the librettist, suggested a prayer for the Israelites before and after the passage of the host through the cleft waters. Rossini instantly seized the idea, and, springing from bed in his night-shirt, wrote the music with almost inconceivable rapidity, before his embarrassed visitors recovered from their surprise. The same evening the magnificent _Dal tuo stellato soglio_ ("To thee, Great Lord") was performed with the opera. Let Stendhall, Rossini's biographer, tell the rest of the story--"The audience was delighted as usual with the first act, and all went well till the third, when, the passage of the Red Sea being at hand, the audience as usual prepared to be amused. The laughter was just beginning in the pit, when it was observed that Moses was about to sing. He began his solo, the first verse of a prayer, which all the people repeat in chorus after Moses. Surprised at this novelty, the pit listened and the laughter entirely ceased. The chorus, exceedingly fine, was in the minor. Aaron continues, followed by the people. Finally, Eleia addresses to Heaven the same supplication, and the people respond. Then all fall on their knees and repeat the prayer with enthusiasm; the miracle is performed, the sea is opened to leave a path for the people protected by the Lord. This last part is in the major. It is impossible to imagine the thunders of applause that resounded through the house; one would have thought it was coming down. The spectators in the boxes, standing up and leaning over, called out at the top of their voices, '_Bello, bello! O che bello!_' I never saw so much enthusiasm nor such a complete success, which was so much the greater, inasmuch as the people were quite prepared to laugh.... I am almost in tears when I think of this prayer. This state of things lasted a long time, and one of its effects was to make for its composer the reputation of an assassin, for Dr. Cottogna is said to have remarked--'I can cite to you more than forty attacks of nervous fever or violent convulsions on the part of young women, fond to excess of music, which have no other origin than the prayer of the Hebrews in the third act, with its superb change of key.'" Thus, by a stroke of genius, a scene which first impressed the audience as a
