La Juive
Perhaps the most celebrated Jewish heroine was Rachel, in Jacques Halévy's grand opera "La Juive" (1835). Rachel falls in love with a Christian prince who disguises himself as a Jew to court her. When Rachel realizes the deception, she denounces him, damning herself. The cardinal promises her that she will be saved if she converts to Christianity. She refuses and is sent to her death in a cauldron of boiling water.
