backstage antics of two high-flown sopranos. Salieri then returned to Paris for the premiere of his tragédie Lyrique Les Horaces (The Horatii), which proved a failure, which was more than made up for with his next Parisian opera Tarare, with a libretto by Beaumarchais. This was intended to be the of reform opera, a completely new synthesis of poetry and music that was an 18th-century anticipation of the ideals of Richard Wagner. Salieri also created a sacred cantata Le Judgment dernier (The Last Judgement). The success of his opera Tarare was such that it was soon translated into Italian at Joseph II's behest by Lorenzo Da Ponte as Axur, re d'Ormus (Axur, king of Hormuz) and staged at the royal wedding of Franz II in 1788. Late Viennese operas (1788–1804) In 1788 Salieri returned to Vienna, where he remained for the rest of his life. In that year he became Kapellmeister of the Imperial Chapel upon the death of Giuseppe Bonno; as Kapellmeister he conducted the music and musical school connected with the chapel until shortly before his death, being officially retired from the post in 1824. His Italian adaptation of Tarare, Axur proved to be his greatest international success. Axur was widely produced throughout Europe and it even reached South America with the exiled royal house of Portugal in 1824. Axur and his other new compositions completed by 1792 marked the height of Salieri's popularity and his influence. Just as his apogee of fame was being reached abroad, his influence in Vienna began to diminish with the death of Joseph II in 1790. Joseph's death deprived Salieri of his greatest patron and protector. During this period of imperial change in Vienna and revolutionary ferment in France, Salieri composed two additional extremely innovative musical dramas to libretti by Giovanni Casti. Due, however, to their satiric and overtly liberal political inclinations, both operas were seen as unsuitable for public performance in the politically reactive cultures of Leopold II and later Francis II. This resulted in two of his most original operas being consigned to his desk drawer, namely Cublai, gran kan de' Tartari (Kublai Grand Kahn of Tartary) a satire on the autocracy and court intrigues at the court of the Russian Tsarina, Catherine the Great, and Catilina a semi-comic/semi-tragic account of the Catiline conspiracy that attempted to overthrow the Roman republic during the consulship of Cicero. These operas were composed
