Marie Wilt (also Maria Vilda and Marie Liebenthaler) (30 January 1833 – 24 September 1891) was an Austrian dramatic coloratura soprano.
 Possessing a wide vocal range with a significant amount of power and flexibility, Wilt sang a wide repertoire that encompassed the operas of Wolfgang Amadeus Mozart, the German operas of Richard Wagner, the grand operas of Giuseppe Verdi, and the bel canto operas of Bellini, Rossini, and Donizetti.
 She sang for many years at the Vienna Hofoper (now Vienna State Opera) and for a number of seasons at the Royal Opera House, Covent Garden in London.

Oberon, or The Elf King (German: "Oberon oder König der Elfen" ), or simply Oberon, originally known as Huon and Amanda (German: "Hüon und Amande" ), is a romantic Singspiel in five acts by Friederike Sophie Seyler, based on the poem "Oberon" by Christoph Martin Wieland, which itself was based on the epic romance "Huon of Bordeaux", a French medieval tale.

Styled a "festa teatrale", "Le feste d'Apollo" consists of a prologue and three self-contained acts on the model of French "opéra-ballet" (the court of Parma was passionately interested in French culture).
 Gluck knew the Archduchess Maria Amalia well as she had sung in two of his operas, "Il Parnaso confuso" and "La corona", in Vienna.
 The composer recycled a lot of music from his earlier operas in the score of "Le feste".
 In fact, the whole of the third act, "Orfeo", is a shorter reworking of his most famous piece, "Orfeo ed Euridice" (1762).
 The overture to the prologue is taken from "Telemaco".
 Gluck later reused some of the choruses in two of the operas he wrote for Paris, "Iphigénie en Aulide" and "Iphigénie en Tauride".
