In the darkness of night the Countess and Susanna, having exchanged clothes, come to put their husbands to the proof; Susanna has been warned by Marcellina of Figaro's designs. Scarcely is the Countess alone, when she is alarmed by the approach of Cherubino, who presses a kiss on the supposed Susanna; the Count, entering on the instant, salutes the page with a box on the ear, which is received instead by the listening Figaro. Alone with the Countess, the Count addresses her in the most endearing terms, presents her with money, and with a costly ring, and endeavours to go off with her; she escapes him in the darkness, and he seeks her in vain. In the meantime Susanna, as the Countess, comes to the enraged Figaro, but forgetting for a moment to disguise her voice, he recognises her, and turns the tables by proposing to her to revenge herself for her lord's want of faith by her own, whereupon she makes herself known by {DA PONTE'S LIBRETTO.} (77) boxing his ears. Peace is easily restored by his explanation, and as the Count approaches, seeking his Susanna, they continue to counterfeit love. The Count in a rage calls for his people with torches, Figaro's friends hasten in, and with them the Countess. The Count, to his shame, discovers that it was his wife who accepted his presents and declarations of love, and the pardon which she accords to him brings the confusion to an end. Such is a mere outline of this amusing play of intrigue, where one knot twisting in with another, one embarrassment growing out of another, call forth ever and again fresh contrivances, while an abundance of effective situations and characteristic detail make the witty and satirical dialogue one of the most graphic character pictures of the time.[3] Da Ponte has arranged his libretto with much skill, having no doubt received important aid from Mozart himself. The progress of the piece is left almost unaltered, the necessary abbreviations being judiciously made.[4] Thus, the lengthy trial scene is omitted, and only the result in its bearing on the plot is communicated. Sometimes an under-plot is added, such as Basilio's appearance as Marcellina's lover. The clearness of the plot is not often endangered, as it certainly is by the alteration which omits all mention of a son of Bartolo and Marcellina previous to their recognition of Figaro as their offspring. The musical pieces are introduced with admirable discrimination in such positions as to allow free and natural scope to the musical rendering of each situation without hindering the progress of the plot, and this is no small praise in such a piece as "Figaro." The whole scheme of the drama demands that quite as much attention shall be given to the ensemble movements and finales as {LE NOZZE DI FIGARO.} (78)
