offered to create the part of Tonio, and did so at the first performance of the opera at the Teatro dal Verme, Milan, on May 17, 1892. Leoncavallo's opera turns on a tragical ending to a comedy which is incorporated in the play. The comedy is a familiar one among the strolling players who perform at village fairs in Italy, in which Columbina, Pagliaccio, and Arlecchino (respectively the Columbine, Clown, and Harlequin of our pantomime) take part. Pagliaccio is husband to Colombina and Arlecchino is her lover, who hoodwinks Pagliaccio. There is a fourth character, Taddeo, a servant, who makes foolish love to Columbina and, mingling imbecile stupidity with maliciousness, delights in the domestic discord which he helps to foment. The first act of the opera may be looked upon as an induction to the conventional comedy which comes to an unconventional and tragic end through the fact that the Clown (Canio) is in real life the husband of Columbine (Nedda) and is murderously jealous of her; wherefore, forgetting himself in a mad rage, he kills her and her lover in the midst of the mimic scene. The lover, however, is not the Harlequin of the comedy, but one of the spectators whom Canio had vainly sought to identify, but who is unconsciously betrayed by his mistress in her death agony. The Taddeo of the comedy is the clown of the company, who in real life entertains a passion for Nedda, which is repulsed, whereupon he also carries his part into actuality and betrays Nedda's secret to Canio. It is in the ingenious interweaving of these threads--the weft of reality with the warp of simulation--that the chief dramatic value of Leoncavallo's opera lies.
