In 1791, an anonymous author wrote a scathing and vicious pamphlet attacking the work and character of Mozart's most famous librettist, Lorenzo Da Ponte. "Anti-Da Ponte" is translated here for the first time in its entirety from the German with facing pages of the book showing the two languages next to each other for convenient comparison. The first part of the pamphlet is a response to an actual letter that Da Ponte wrote to emperor Leopold II, while the second part takes the form of a mock trial in which famous figures such as Mozart and Salieri denounce the librettist. The introduction and notes are helpful for understanding the context as well as the unusual references and turns of phrase that abound in "Anti-Da Ponte."
