It is a historical work portraying the Renaissance-era Italian aristocrat Lucrezia Borgia. The play (along with "Angelo, Tyrant of Padua") is believed to have been a major influence on Oscar Wilde's "The Duchess of Padua" (1891).
Document 2: Maria Stuarda: Maria Stuarda (Mary Stuart) is a tragic opera ("tragedia lirica"), in two acts, by Gaetano Donizetti, to a libretto by Giuseppe Bardari, based on Andrea Maffei's translation of Friedrich Schiller's 1800 play "Maria Stuart".
Document 3: Le duc d'Albe: Le duc d'Albe (its original French title) or Il duca d'Alba (its later Italian title) is an opera in three acts originally composed by Gaetano Donizetti in 1839 to a French language libretto by Eugène Scribe and Charles Duveyrier. Its title, which translates as "The Duke of Alba", refers to its protagonist Fernando Álvarez de Toledo, 3rd Duke of Alba. The work was intended for performance at the Paris Opéra. However, William Ashbrook notes that "Rosine Stoltz, the director's mistress, disliked her intended role of Hélène and Donizetti put the work aside when it was half completed"
Document 4: Nixon in China: Nixon in China is an opera in three acts by John Adams, with a libretto by Alice Goodman.

When Sellars approached Adams with the idea for the opera in 1985, Adams was initially reluctant, but eventually decided that the work could be a study in how myths come to be, and accepted the project. Goodman's libretto was the result of considerable research into Nixon's visit, though she disregarded most sources published after the 1972 trip.

Document 13: Rita (opera): In 1841, while Donizetti was in Paris waiting for the libretto to be completed for a commission by La Scala, he had a chance encounter with Gustave Vaëz, who had co-written the libretti for two of his earlier operas, "Lucie de Lammermoor" (the French version of "Lucia di Lammermoor") and "La favorite". He asked Vaëz if he could provide a libretto for a short opera to keep him busy while waiting for the La Scala project to advance. Vaëz quickly created "Deux hommes et une femme" ("Two Men and a Woman"), a comic piece in one act consisting of eight musical numbers connected by spoken dialogue. According to Vaëz, Donizetti completed the score in eight days. However, the Opéra-Comique rejected it and Donizetti then had the libretto translated into Italian for an intended performance at the Teatro del Fondo in Naples. Following the death of the Teatro del Fondo's impresario, Domenico Barbaja, the Naples performance fell through. The score, still unperformed, was found in Donizetti's effects when he died in 1848.
