When he had completed the libretto, Marsollier sent it to Dalayrac, who, quick to recognise the splendid possibilities it offered for musical effect, gladly promised his co-operation. The score was soon written, but, for some little time, the authors hesitated to submit it to the Comédie-Italienne, fearing that their attempt to depict madness on the stage was too hazardous, and might expose them to the risk of a disastrous failure. While they were still in doubt, Mlle. Guimard offered them the use of her private theatre, in the Chaussée-d’Antin, for an experimental performance. They gratefully accepted, and it was on the erotic stage of the Temple of Terpsichore, “on those boards whereon the _coryphées_ of the _fricassée_ had so many times bounded,” that Madame Dugazon created the part of Nina, before the usual mixed audience of noblemen, _grandes dames_, and courtesans. The result was a prodigious, an astonishing success, and, on May 15, 1786, the curtain of the Comédie-Italienne rose on _Nina, ou la Folle par amour_. The creation of Nina dominates Madame Dugazon’s whole career and eclipses all her earlier triumphs. Never within the memory of man, says M. Campardon, had there been a like success. The actress threw into the part her whole soul, and it was very often remarked that on the days on which she had been playing Nina, she retained throughout the remainder of the evening the haggard eyes and singular gestures of the unhappy mad woman whom she had just been impersonating. “She played the part,” writes Bouilly, “with a perfection impossible to describe; one must have seen and heard her to form a correct idea of that penetrating voice, of that frenzy, heartrending and yet full of charm, of that energy of expression which thrilled every heart.”[135] Grimm pronounces her in this piece superior to herself and to all the actresses that are the most applauded at the other theatres. “Never,” says he, “was there displayed a sensibility more exquisite and more profound. Never did any one know how to assume more happily the most diverse tones. Never did any one vary them with more correctness. It is the sensibility of her acting that decided essentially the success of the work, for the tears which she has caused to flow do not prevent one from perceiving that it leaves much to desire.”[136] But whatever the shortcomings of _Nina_ may have been, the public seemed resolved to ignore them, and the enthusiasm with which the work and its “inspired interpreter” were received passed all bounds. “When one beheld her, her hair unbound, her eyes staring, a bouquet in her hand, advance towards the grassy bank near which she awaits her ‘_bien-aimé_,’ when the plaints of the poor distracted girl were translated by the naïve and tender music of Dalayrac, it seemed as if emotion had reached its limits. One wept for Nina, as one wept for Garat, Miss Billington, Todi, Maillard, or Saint-Huberty.”[137]
