Question: Are the libretto of Otello and Der Ring des Nibelungen in the same language?

full_context: Document 1: Die Walküre: Die Walküre (The Valkyrie), WWV 86B, is a music drama in three acts by Richard Wagner with a German libretto by the composer. It is the second of the four works that form Wagner's cycle "Der Ring des Nibelungen" ("The Ring of the Nibelung").
Document 2: Macbeth (opera): Macbeth (] ) is an opera in four acts by Giuseppe Verdi, with an Italian libretto by Francesco Maria Piave and additions by Andrea Maffei, based on William Shakespeare's play of the same name.
Document 3: Rhinemaidens: The Rhinemaidens are the three water-nymphs ("Rheintöchter" or "Rhine daughters") who appear in Richard Wagner's opera cycle "Der Ring des Nibelungen". Their individual names are Woglinde, Wellgunde and Flosshilde (Floßhilde), although they are generally treated as a single entity and they act together accordingly. Of the 34 characters in the "Ring" cycle, they are the only ones who did not originate in the Old Norse "Eddas". Wagner created his Rhinemaidens from other legends and myths, most notably the "Nibelungenlied" which contains stories involving water-sprites (nixies) or mermaids. The key concepts associated with the Rhinemaidens in the "Ring" operas—their flawed guardianship of the Rhine gold, and the condition (the renunciation of love) through which the gold could be stolen from them and then transformed into a means of obtaining world power—are wholly Wagner's own invention, and are the elements that initiate and propel the entire drama.
Document 4: Othello: Othello ("The Tragedy of Othello, the Moor of Venice)" is a tragedy by William Shakespeare, believed to have been written in 1603. It is based on the story "Un Capitano Moro" ("A Moorish Captain") by Cinthio, a disciple of Boccaccio, first published in 1565. The story revolves around its two central characters: Othello, a Moorish general in the Venetian army and his unfaithful ensign, Iago. Given its varied and enduring themes of racism, love, jealousy, betrayal, revenge and repentance, "Othello" is still often performed in professional and community theatre alike, and has been the source for numerous operatic, film, and literary adaptations.
Document 5: Richard Wagner: Wilhelm Richard Wagner ( ; ] ; 22 May 181313 February 1883) was a German composer, theatre director, polemicist, and conductor who is primarily known for his operas (or, as some of his later works were later known, "music dramas"). Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Weber and Meyerbeer, Wagner revolutionised opera through his concept of the "Gesamtkunstwerk" ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama. He described this vision in a series of essays published between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle "Der Ring des Nibelungen" ("The Ring of the Nibelung").
Document 6: Der Ring des Nibelungen: Der Ring des Nibelungen (The Ring of the Nibelung), WWV 86, is a cycle of four German-language epic music dramas composed by Richard Wagner. The works are based loosely on characters from the Norse sagas and the "Nibelungenlied". The composer termed the cycle a "Bühnenfestspiel" (stage festival play), structured in three days preceded by a " " ("preliminary evening"). It is often referred to as the Ring Cycle, "Wagner's Ring", or simply "The Ring".
Document 7: Götterdämmerung: Götterdämmerung ( ; Twilight of the Gods), WWV 86D, is the last in Richard Wagner's cycle of four music dramas titled "Der Ring des Nibelungen " ("The Ring of the Nibelung", or "The Ring" for short). It received its premiere at the Bayreuth Festspielhaus on 17 August 1876, as part of the first complete performance of the "Ring".
Document 8: Aida: Aida (] ) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Antonio Ghislanzoni. Set in Egypt, it was commissioned by and first performed at Cairo's Khedivial Opera House on 24 December 1871; Giovanni Bottesini conducted after Verdi himself withdrew. Today the work holds a central place in the operatic canon, receiving performances every year around the world; at New York's Metropolitan Opera alone, "Aida" has been sung more than 1,100 times since 1886. Ghislanzoni's scheme follows a scenario often attributed to the French Egyptologist Auguste Mariette, but Verdi biographer Mary Jane Phillips-Matz argues that the source is actually Temistocle Solera.
Document 9: Otello (1986 film): Otello is a 1986 film based on the Giuseppe Verdi opera of the same name, which was itself based on the Shakespearean play "Othello". The film was directed by Franco Zeffirelli and starred Plácido Domingo in the title role, Katia Ricciarelli as Desdemona and Justino Díaz as Iago. For the movie's soundtrack, Lorin Maazel conducted the Orchestra and Chorus of the Teatro alla Scala. The film premiered in West Germany on August 28, 1986 and received a U.S. theatrical release on September 12, 1986. It was nominated for a Bafta Award and a Golden Globe for Best Foreign Language Film.
Document 10: Rigoletto: Rigoletto (] ) is an opera in three acts by Giuseppe Verdi. The Italian libretto was written by Francesco Maria Piave based on the play "Le roi s'amuse" by Victor Hugo.

Document 11: Il trovatore: Il trovatore (] ; Italian for "The Troubadour") is an opera in four acts by Giuseppe Verdi to an Italian libretto largely written by Salvadore Cammarano, based on the play "El trovador" (1836) by Antonio García Gutiérrez. It was Gutiérrez's most successful play, one which Verdi scholar Julian Budden describes as "a high flown, sprawling melodrama flamboyantly defiant of the Aristotelian unities, packed with all manner of fantastic and bizarre incident."
Document 12: Aroldo: Aroldo (] ) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Francesco Maria Piave, based on and adapted from their earlier 1850 collaboration, "Stiffelio". The first performance was given in the Teatro Nuovo Comunale in Rimini on 16 August 1857.
