Answer
Der Rosenkavalier, an opera by Richard Strauss, revolves around the presentation of a silver rose. Set in 18th-century Vienna, the plot unfolds through the lives of the Marschallin, a retired field marshal's wife, and Octavian, a young man who becomes entangled in a love triangle involving the Marschallin and Baron Ochs. The opera explores themes of love, deception, and social hierarchies, culminating in the symbolic exchange of the silver rose.
