Question: Cendrillon, a three act operetta, premiered on the 23rd of April in this typical Paris setting.
Sentence (from "Cendrillon (Viardot)"): Historians are unsure of when the opera was actually composed, although it is thought to be after the death of Viardot's friend (and possibly her lover) Ivan Turgenev in 1883 as he did not write the libretto.
Relevant evidence: No
