Perhaps at no period of her life, though, did Mme. Viardot create a stronger feeling than when she appeared in Berlin in the spring of 1847 as _Rachel_ in Halevy's "La Juive." It was a German version, but the singer was perfect mistress of the language, and though the music of the opera was by no means well suited to the character of her voice, its power as a dramatic performance and the passion of the singing established a complete supremacy over all classes of hearers. The exhibition on the part of this staid and phlegmatic German community was such as might only be predicated of the volcanic temperament of Rome or Naples. The roar of the multitude in front of her lodgings continued all night, and it was dawn before she was able to retire to rest. The versatility and kind heart of Mme. Viardot were illustrated in an occurrence during this Berlin engagement. She had been announced as _Alice_ in "Robert le Diable," when the _Isabella_ of the evening, Mlle. Tuezck, was taken ill. The _impressario_ tore his hair in despair, for there was no singer who could be substituted, and a change of opera seemed to be the only option. Mme. Viardot changed the gloom of the manager to joy. Rather than disappoint the audience, she would sing both characters. This she did, changing her costume with each change of scene, and representing in one opera the opposite _roles_ of princess and peasant. One can imagine the effect of this great feat on that crowded Berlin audience, who had already so warmly taken Pauline Viardot to their hearts. Berlin, Vienna, Hamburg, Dresden, Frankfort, Leipsic, and other German cities were the scenes of a series of triumphs, and everywhere there was but one voice as to her greatness as an artist, an excellence not only great, but unique of its kind. Her repertoire at this time consisted of _Desdemona, Cenerentola, Rosina, Camilla (in "Gli Orazi"), Arsace, Norma, Ninetta, Amina, Romeo, Lucia, Maria di Rohan, Leonora ("La Favorita" ), Zerlina, Donna Anna, Iphigenie (Gluck), the Rachel of Halevy, and the Alice and Valentine of Meyerbeer_.
