Question: Who wrote Les Erinnyes, the French verse drama based Aeschylus' Oresteia?
Context: Agamemnon is an opera in one act by composer Felix Werder.  Werder used his own libretto for the work which is based on Gilbert Murray's English language translation of the Ancient Greek tragedy "Oresteia" by Aeschylus.  The work was composed in 1967 with the title "The Agamemnon of Aeschylus", and was first performed under that name in that year on ABC radio.  Afterwards Werder reworked some of the music and retitled the piece "Agamemnon" for the opera's first staged performance at the Grant Street Theatre in Melbourne on 1 June 1977 in a production led by conductor Hiroyuki Iwaki.  The opera uses Twelve-tone technique in its composition and is structured in 25 sections. Oresteia ("Орестея" in Cyrillic) is an opera in three parts, eight tableaux, with music by Sergei Taneyev, composed during 1887-1894.  The composer titled this work, his only opera, a "musical trilogy."  The Russian libretto was adapted by A.A. Wenkstern from "The Oresteia" of Aeschylus.  The opera was premiered on October 29 [O.S. October 17] 1895 at the Mariinsky Theatre.  Nikolai Rimsky-Korsakov wrote that soon after the premiere, the Mariinsky management made cuts to the opera, which angered Taneyev. The Oresteia (Ancient Greek: Ὀρέστεια ) is a trilogy of Greek tragedies written by Aeschylus concerning the murder of Agamemnon by Clytaemnestra, the murder of Clytaemnestra by Orestes, the trial of Orestes, the end of the curse on the House of Atreus and pacification of the Erinyes.  The trilogy—consisting of "Agamemnon" (Ἀγαμέμνων ), "The Libation Bearers" (Χοηφóρoι ), and "The Eumenides" (Εὐμενίδες )—also shows how the Greek gods interacted with the characters and influenced their decisions pertaining to events and disputes.  The only extant example of an ancient Greek theatre trilogy, the "Oresteia" won first prize at the Dionysia festival in 458 BC.  Many consider the "Oresteia" to be Aeschylus' finest work.  The principal themes of the trilogy include the contrast between revenge and justice, as well as the transition from personal vendetta to organized litigation.  "Orestia" originally included a satyr play, "Proteus" (Πρωτεύς ), following the tragic trilogy, but all except a single line of "Proteus" has been lost. Atreides is Yannis Zouganelis' third studio album.  The album contains songs written for the play of the same name which was a "montage of Greek tragedies based on the myth of the House of Atreus".  The play included pieces from Oresteia by Aeschylus, Electra by Sophocles, and Iphigenia at Aulis, Iphigenia in Tauris, and Orestes by Euripides translated and adapted from the Ancient Greek by Kostas Myris, who also wrote the lyrics of the songs which were sung by Vasilis Papakonstantinou.  The play was performed by "Theatro Erevnas" of Dimitris Potamitis at the Mount Lycabettus theatre in Athens and later broadcast by the Greek national television ERT on 12 November 1979. Proserpine is a verse drama written for children by the English Romantic writers Mary Shelley and her husband Percy Bysshe Shelley.  Mary wrote the blank verse drama and Percy contributed two lyric poems.  Composed in 1820 while the Shelleys were living in Italy, it is often considered a partner to the Shelleys' play "Midas".  "Proserpine" was first published in the London periodical "The Winter's Wreath" in 1832.  Whether the drama was ever intended to be staged is a point of debate among scholars. Midas is a verse drama in blank verse by the Romantic writers Mary Shelley and Percy Bysshe Shelley.  Mary wrote the drama and Percy contributed two lyric poems to it.  Written in 1820 while the Shelleys were living in Italy, Mary Shelley tried unsuccessfully to have the play published by children's magazines in England in the 1830s; however, it was not published until A. Koszul's 1922 scholarly edition.  Whether or not the drama was ever meant to be staged is a point of debate among scholars.  The play combines the stories of the musical contest between Apollo and Pan and that of King Midas and his ability to turn everything he touches to gold. Verse drama is any drama written as verse to be spoken; another possible general term is poetic drama.  For a very long period, verse drama was the dominant form of drama in Europe (and was also important in non-European cultures).  Greek tragedy and Racine's plays are written in verse, as is almost all of Shakespeare's drama, Ben Jonson, John Fletcher and others like Goethe's "Faust". Antilabe (from the Greek: ἀντι "mutually" or "corresponding", λαβή, "grip" or "handle") is a rhetorical technique in verse drama or closet drama, in which a single verse line of dialogue is distributed on two or more characters, voices, or entities.  The verse usually maintains its metric integrity, while the line fragments spoken by the characters may or may not be complete sentences.  In the layout of the text the line fragments following the first one are often indented ("dropped line") to show the unity of the verse line.
