; Opera Landmarks
: '''The Marriage of Figaro (1786)''' → Mozart's "Perfect" comedy, which is both a beautiful story and a dangerous political attack on the aristocracy.
: '''The Ring of the Nibelung''' → Wagner's 16-hour epic that required the building of a special theater and influenced 'The Lord of the Rings' and 'Star Wars.'
: '''La Bohème (1896)''' → Puccini's story of young artists in Paris, which was later adapted into the Broadway musical "RENT."
: '''Carmen (1875)''' → Bizet's opera about a rebellious woman in Spain, which was at first a failure but is now the most-performed opera in the world.
