"With Mlle. Cruvelli," says this writer, "_Fidelio_ is governed throughout by one purpose, to which everything is rendered subservient. Determination to discover and liberate her husband is the mainspring not only of all her actions, and the theme of all her soliloquies, but, even when others likely to annunce her design in any way are acting or speaking, we read in the anxious gaze, the breathless anxiety, the head bent to catch the slightest word, a continuation of the same train of thought and an ever-living ardor in the pursuit of the one cherished object. In such positions as these, where one gifted artist follows nature with so delicate an appreciation of its most subtile truths, it is not easy for a character occupying the background of the stage picture to maintain (although by gesture only) a constant commentary upon the words of others without becoming intrusive or attracting an undue share of attention. Yet Cruvelli does this throughout the first scene (especially during the duet betwixt _Rocco_ and _Pizarro_, in which _Fidelio_ overhears the plan to assassinate her husband) with a perfection akin to that realized by Rachel in the last scene of 'Les Horaces,' where Camille listens to the recital of her brother's victory over her lover; and the result, like that of the chorus in a Greek drama, is to heighten rather than lessen the effect. These may be considered minor points, but, as necessary parts of a great conception, they are as important, and afford as much evidence of the master mind, as the artist's delivery of the grandest speeches or scenes." "Mlle. Cruvelli," observes another critic, "has the power of expressing joy and despair, hope and anxiety, hatred and love, fear and resolution, with equal facility. She has voice and execution sufficient to master with ease all the trying difficulties of the most trying and difficult of parts." _Norma_ was Sophie's second performance. "Before the first act was over, Sophie Cruvelli demonstrated that she was as profound a mistress of the grand as of the romantic school of acting, as perfect an interpreter of the brilliant as of the classical school of music." She represented _Fidelio_ five times and _Norma_ thrice.
