Document 3: Euryanthe: Euryanthe is a German "grand, heroic, romantic" opera by Carl Maria von Weber, first performed at the Theater am Kärntnertor, Vienna on 25 October 1823. Though acknowledged as one of Weber's most important operas, the work is rarely staged because of the weak libretto by Helmina von Chézy (who, incidentally, was also the author of the failed play "Rosamunde", for which Franz Schubert wrote music). "Euryanthe" is based on the 13th-century romance ""L'Histoire du très-noble et chevalereux prince Gérard, comte de Nevers et la très-virtueuse et très chaste princesse Euriant de Savoye, sa mye.""
Document 4: Christoph Willibald Gluck: Christoph Willibald (Ritter von) Gluck (] ; 2 July 1714 – 15 November 1787) was a composer of Italian and French opera in the early classical period. Born in the Upper Palatinate (now part of Germany) and raised in Bohemia, he gained prominence at the Habsburg court at Vienna, where he brought about the practical reform of opera's dramaturgical practices that many intellectuals had been campaigning for over the years. With a series of radical new works in the 1760s, among them "Orfeo ed Euridice" and "Alceste", he broke the stranglehold that Metastasian "opera seria" had enjoyed for much of the century.

Document 9: Nick Bottom: Nick Bottom is a character in Shakespeare's "A Midsummer Night's Dream" who provides comic relief throughout the play. A weaver by trade, he is famously known for getting his head transformed into that of a donkey by the elusive Puck. Bottom and Puck are the only two characters who converse with and progress the three central stories in the whole play. Puck is first introduced in the fairies' story and creates the drama of the lovers' story by messing up who loves whom, and places the donkey head on Bottom's in his story. Similarly, Bottom is performing in a play in his story intending it to be presented in the lovers' story, as well as interacting with Titania in the fairies' story.
Document 10: Johann Friedrich Kind: Johann Friedrich Kind (4 March 1768 Leipzig – 24 June 1843) was a German dramatist, most famous for writing the libretto for Carl Maria von Weber's opera "Der Freischütz" (1821).
Document 11: Queen Mab: Queen Mab (pronunciation: "M/ă/v") is a fairy referred to in William Shakespeare's play "Romeo and Juliet", where "she is the fairies' midwife." Later, she appears in other poetry and literature, and in various guises in drama and cinema. In the play, her activity is described in a famous speech by Mercutio written originally in prose and often adapted into iambic pentameter, in which she is described as a miniature creature who performs midnight pranks upon sleepers. Being driven by a team of atomies, she rides her chariot over their noses and "delivers the fancies of sleeping men." Additionally, while driving "O'er ladies' lips, who straight on kisses dream," she was known to change her mind and instead "plague" "ladies' lips" "with blisters" if she smelled "sweetmeats" or candied fruit eaten to sweeten their breath. Along with this interpretation, others believe the blisters were a reference to the plague or to herpes simplex. She is also described as a midwife to help sleepers 'give birth' to their dreams. She may be a figure borrowed from folklore, and though she is often associated with the Irish Medb in popular culture, and has been suggested by historian Thomas Keightley to be from "Habundia", a more likely origin for her name would be from Mabel and the Middle English derivative "Mabily" (as used by Chaucer) all from the Latin "amabilis" ("lovable").
