Droit du seigneur
In Mozart's "The Marriage of Figaro", which premiered in 1786 with a libretto by Lorenzo Da Ponte, the comic plot revolves around the successful efforts of the young bride and groom, Figaro and Susanna, to block the efforts of the unfaithful Count Almaviva to seduce Susanna. To achieve his aim, the frustrated Count threatens to reinstitute "droit du seigneur". It was based on a play by Pierre Beaumarchais.
Der Graf von Luxemburg
Like "The Merry Widow", "Der Graf von Luxemburg " deals with the themes of how the promise of wealth affects love and marriage, and the contrast between the gaiety of Parisian society and Slavic seriousness. The libretto was written by Alfred Maria Willner, Robert Bodanzky and Leo Stein. Stein had previously worked with Lehár on his 1904 "Der Göttergatte", and Bodanzky had co-authored the librettos for both "Peter und Paul reisen ins Schlaraffenland" and "Mitislaw der Moderne". The libretto for "Der Graf von Luxemburg" was not completely new. It was a re-working of the one written by Alfred Willner and Bernhard Buchbinder twelve years earlier for Johann Strauss' unsuccessful operetta "Die Göttin der Vernunft" ("The Goddess of Reason").
