At the end of FAUST, Marguerite elects to be put to death rather than escape with Faust. This ending is a redemption and Marguerite (in our production) walks toward the guillotine with the knowledge that her soul will be saved and rise up to the heavens. "Christ is risen" sings the chorus from offstage.
One of our patrons came to the show on Saturday night and thought she saw a cross at this moment. She loved the production and came back on Tuesday, but didn't see the cross and actually wrote in to inquire why we changed the staging. Well we didn't change the staging, there never was a cross, but she imagined one. Kind of a powerful thing--opera charged imagination.
