At the conclusion of Giacomo Puccini’s opera Tosca, the title character discovers that her lover, Mario Cavaradossi, has been executed by a real firing squad, despite her previous arrangement with the villainous Scarpia for a mock execution.

Upon realizing that Scarpia betrayed her, Tosca is pursued by Spoletta, who arrives to arrest her for Scarpia’s murder. In a final act of defiance and despair, she climbs the battlements of the Castel Sant’Angelo. Crying out that she will meet Scarpia before God, she leaps to her death.1
