in the courts of the Austrian nobility, blamed the Italians in general and Salieri in particular for all of Mozart's difficulties in establishing himself in Vienna. Mozart wrote to his father in May 1783 about Salieri and Lorenzo Da Ponte, the court poet: "You know those Italian gentlemen; they are very nice to your face! Enough, we all know about them. And if [Da Ponte] is in league with Salieri, I'll never get a text from him, and I would love to show him what I can really do with an Italian opera." In July 1783, he again wrote to his father of "a trick of Salieri's", one of several letters in which Mozart accused Salieri of trickery. Decades after Mozart's death, a rumor began to circulate that Mozart had been poisoned by Salieri. This rumor has been attributed by some to a rivalry between the German and the Italian schools of music. Carl Maria von Weber, a relative of Mozart by marriage whom Wagner has characterized as the most German of German composers, is said to have refused to join the Ludlamshöhle (Ludlam's cave), a social club of which Salieri was a member, and avoided having anything to do with him. These rumors then made their way into popular culture. Albert Lortzing's Singspiel Szenen aus Mozarts Leben LoWV28 (1832) and the popular 1984 film Amadeus uses the cliché of the jealous Salieri trying to hinder Mozart's career. Ironically, Salieri's music was much more in the tradition of Gluck and Gassmann than of the Italians like Paisiello or Cimarosa. In 1772, Empress Maria Theresa commented on her preference for Italian composers over Germans like Gassmann, Salieri, or Gluck. While Italian by birth, Salieri had lived in imperial Vienna for almost 60 years and was regarded by such people as the music critic Friedrich Rochlitz as a German composer. The biographer Alexander Wheelock Thayer believes that Mozart's rivalry with Salieri could have originated with an incident in 1781, when Mozart applied to be the music teacher of Princess Elisabeth of Württemberg, and Salieri was selected instead because of his reputation as a singing teacher. The following year Mozart once again failed to be selected as the princess's piano teacher. "Salieri and his tribe will move heaven and earth to put it down", Leopold Mozart wrote to his daughter Nannerl. But at the time of the premiere of Figaro, Salieri was busy
