Virginia Zeani was a Romanian-born opera singer who sang leading soprano roles in the opera houses of Europe and North America.

Dialogues des Carmélites, FP 159, is an opera in three acts, divided into twelve scenes with linking orchestral interludes, with music and libretto by Francis Poulenc, completed in 1956. Poulenc wrote the libretto for his second opera after the work of the same name by Georges Bernanos. This is a fictionalized version of the story of the Martyrs of Compiègne, Carmelite nuns who, in 1794 during the closing days of the Reign of Terror during the French Revolution, were guillotined in Paris for refusing to renounce their vocation.
