Tristan und Isolde
Isolde, promised to King Marke, travels to Cornwall under Tristan’s escort. She and Tristan drink what they believe is a death potion, but it is a love potion, and they confess their passion. Marke discovers them together; Tristan is wounded in a fight and taken to his castle in Brittany. Isolde arrives as Tristan dies. Marke comes to unite the lovers, but Isolde sings of Tristan’s transfiguration and dies beside him.
