Rosine Bloch

[6] Although Bloch was striking in appearance with an ample, rich-timbred voice, it had become apparent over time that her portrayals lacked the "human quality" necessary for her to become a major star.

[7] She also created two roles, Lysis in the world premiere of Jules Duprato's 1-act La Fiancée de Corinthe, which had a libretto by Camille du Locle and was first performed on 21 October 1867, but was an opera that would soon fall into obscurity after only 14 representations,[8] and Claribel in Eugène Diaz's 3-act La Coupe du Roi de Thulé, which had a libretto by L. Gallet and Edouard Blau and premiered on 10 January 1873, but would only be performed 21 times.

The soprano Hélène Brunet-Lafleur, who was cast in the leading role of Odette, abandoned the Lyrique's production, and Perrin allowed Bloch to take on the part.

[15] Verdi had considered casting Bloch as Eboli in the premiere of his opera Don Carlos in 1867, but finally selected Pauline Guéymard-Lauters for that role.

[16] The soprano Teresa Stolz, who attended the dress rehearsal for the Paris premiere of Aida with Verdi's wife, described Bloch as "a most beautiful Amneris: she may not be an 'eagle,' but in any case, she is much better than our two Milan Amnerises (of this year).
