[E] "But no real student can have studied the score deeply, or listened discriminatingly to a good performance, without discovering that there is a tremendous chasm between the conventional aims of the Italian poet in the book of the opera and the work which emerged from the composer's profound imagination. Da Ponte contemplated a dramma giocoso; Mozart humored him until his imagination came within the shadow cast before by the catastrophe, and then he transformed the poet's comedy into a tragedy of crushing power. The climax of Da Ponte's ideal is reached in a picture of the dissolute Don wrestling in idle desperation with a host of spectacular devils, and finally disappearing through a trap, while fire bursts out on all sides, the thunders roll, and Leporello gazes on the scene, crouched in a comic attitude of terror, under the table. Such a picture satisfied the tastes of the public of his time, and that public found nothing incongruous in a return to the scene immediately afterward of all the characters save the reprobate, who had gone to his reward, to hear a description of the catastrophe from the buffoon under the table, and platitudinously to moralize that the perfidious wretch, having been stored away safely in the realm of Pluto and Proserpine, nothing remained for them to do except to raise their voices in the words of the "old song,"

"Questo è il fin di chi fa mal:
E dei perfidi la morte
Alla vita è sempre ugual."
