a young composer known mostly for comic pieces and so the opera was originally billed in the press as being a new work by Gluck with some assistance from Salieri, then shortly before the premiere of the opera the Parisian press reported that the work was to be partly by Gluck and partly by Salieri, and finally, after popular and critical success on stage, the opera was acknowledged in a letter to the public by Gluck as being wholly by the young Salieri. Les Danaïdes was received with great acclaim and its popularity with audiences and critics alike produced several further requests for new works for Paris audiences by Salieri. Les Danaïdes followed in the tradition of reform that Gluck had begun in the 1760s and that Salieri had emulated in his earlier opera Armida. Salieri's first French opera contained scenes of great solemnity and festivity, but overshadowing it all was darkness and revenge. The opera depicted politically motivated murder, filial duty and love in conflict, tyrannicide, and finally eternal damnation. The opera, with its dark overture, lavish choral writing, many ballet scenes, and electrifying finale depicting a glimpse of hellish torture, kept the opera on the stage in Paris for over forty years. A young Hector Berlioz recorded the deep impression this work made on him in his Mémoires. Upon returning to Vienna following his success in Paris, Salieri met and befriended Lorenzo Da Ponte and had his first professional encounters with Mozart. Da Ponte wrote his first opera libretto for Salieri, Il ricco d'un giorno (A rich man for a day) in 1784, which was not a success. Salieri next turned to Giambattista Casti as a librettist; a more successful set of collaborations flowed from this pairing. In the meantime, Da Ponte began working with Mozart on Le Nozze di Figaro (The Marriage of Figaro). In 1785 Salieri produced one of his greatest works with the text by Casti, La Grotta di Trofonio (The cave of Trophonius), the first opera buffa published in full score by Artaria. Shortly after this success, Joseph II had Mozart and Salieri each contribute a one-act opera and/or Singspiel for production at a banquet in 1786. Salieri collaborated with Casti to produce a parody of the relationship between poet and composer in Prima la musica e poi le parole (First the music and then the words). This short work also highlighted the typical
