Libretto of The Magic Flute

Yvain, portrayed in a 15th-century French manuscript. Unlike Tamino, he vanquishes his menacing reptile.

• In work with D. D. Roy Owen, Peter Branscombe notes strong resemblances between the opening scenes of The Magic Flute and episodes of the medieval romance Yvain by Chrétien de Troyes (c. 1177). This work attracted attention in Mozart and Schikaneder's time and appeared in a 1786–7 German translation by K. J. Michaeler, a member of the same Masonic lodge as Mozart. Yvain offers the following possible models: an imperiled hero in a desolate countryside, carrying a bow and rendered unconscious, is rescued by three ladies, who bring him to a high-born mistress who is in need of a hero's services. In another scene of Yvain (which Owen and Branscombe suggest Schikaneder conflated with the first), the hero encounters a sort of wild man in dress so outlandish that he doubts his humanity; like Papageno, this wild man must assure the hero that he is human.[2]
• A major source appears to have been the 1731 novel Life of Sethos by the French author Jean Terrasson. The work appeared in a German translation by Matthias Claudius in 1777–8. Branscombe sees this a possible source for the serpent that appears in the opening scene, for the trials of water and fire, for the words sung by the Two Armed Men, and for the text of Sarastro's hymn "O Isis und Osiris." The connection is sufficiently close that Branscombe even suggests that modern directors attempting a new production should consult Sethos carefully for the hints it provides concerning what Mozart and Schikaneder would have wanted in terms of production and stage design.[3]
• The long essay "Über die Mysterien der Ägypter" ("On the mysteries of the Egyptians"), published by the Vienna scientist and Freemason Ignaz von Born in the first issue of the Masonic journal Journal für Freymaurer in 1784. This work describes among other things the worship of Isis and Osiris, the gods to whom Sarastro and his priests pray. It also is a possible source for the passages of overt misogyny, discussed below, that often perturb modern readers of Schikaneder's libretto.[4]

• The series of three books entitled Dschinnestan published by Christoph Martin Wieland in 1786 to 1789 contains a total of 19 fairy tales. Some of these are retold stories, others were made up by Wieland or by his collaborator J. A. Liebeskind. Various of these stories – which were being separately published in Vienna at the time The Magic Flute was being written – are held to have influenced Schikaneder's Magic Flute libretto.
  • "Adis und Dahy" contains a model for the character Monostatos; he is a black slave who watches over the heroine and is later punished by his master.[5]
  • "Neangir und seine Brüder" ("Neangir and his brothers") provides a model for Tamino's famous aria "Dies Bildnis ist bezaubernd schön": a hero falls in love with a woman merely by seeing her portrait and sets off to rescue her. As Branscombe notes, this situation is common enough in literature, but "Neangir" contains many of the actual words used in the text Schikaneder wrote for this aria.[5]
  • "Die klugen Knaben" ("The clever boys") is perhaps the model for the Three Boys. They give wise advice to characters in the story, including a somewhat more verbose version of Schikaneder's "Sei standhaft, duldsam, und verschwiegen" ("Be steadfast, resolute, and discreet"). They also descend from the skies "on a white shining cloud to prevent a tragic outcome", perhaps the model for the Three Boys' interventions to prevent the intended suicides of Pamina and Papageno.[6]
  • "Lulu, oder die Zauberflöte" ("Lulu, or the Magic Flute"). Branscombe takes the view that this story provided little more than the title of the opera.

The Schikaneder troupe prior to the premiere of The Magic Flute had developed considerable experience with performing fairy tale operas with similar plots, characters, and singers. Two bear a particularly strong relationship to The Magic Flute:

• Oberon, a romantic Singspiel in five acts by Friederike Sophie Seyler, premiered in a plagiarized version by Karl Ludwig Giesecke, later the first First Slave in The Magic Flute. Its source is a verse epic of the same title by Wieland.[7]
• Der Stein der Weisen oder Die Zauberinsel, premiered 1790. This, too, was based on a source in Wieland's Dschinnestan".[7]

A Masonic lodge meeting of Mozart's day, once thought to portray Mozart's own lodge; see Mozart and Freemasonry for discussion.

A very long tradition asserts that Freemasonry plays a major role in the content of Schikaneder's libretto.[8] Mozart was an active Mason in Vienna, and wrote a substantial quantity of music for his own lodge, including in 1791 (see Mozart and Freemasonry). Schikaneder had been a Mason in Regensburg (1786–7) for a few months before his lodge suspended him.[9]

The simpler accounts of Masonic influence in The Magic Flute assume that Masonry provided a system of values, symbolism, and ritual for the opera, but no part of the narrative. More elaborate accounts suggest that the opera was intended as an allegory with a hidden Masonic agenda. For instance, the evil Queen of the Night is sometimes taken to be an emblem for the empress Maria Theresa, who was hostile to Freemasonry in Austria during her reign (1740–1780).

It remains a near-consensus that the opera is in a sense Masonic. However, the Mozart scholar David J. Buch has expressed a contrarian view, suggesting that Masonic interpretations have been oversold. His key point is that careful study of some of the other possible sources, such as those mentioned above, provides alternative origins for elements of the libretto thought to be Masonic. Buch is particularly skeptical of allegorical Masonic interpretations, since libretti with such hidden agendas do not appear to have been commonly created in Mozart and Schickaneder's day.[10]

The Hanswurst character was a mainstay of the popular theater tradition in Vienna, dating back decades before 1791. This character is earthy, wily, and charming, and Papageno survives in modern times as the best known representative of his type. During the period that the Schikaneder troupe was successfully mounting fairy tale operas, it also produced a series of musical comedies featuring Schikaneder in a Hanswurst-like role. These consisted of Der Dumme Gärtner aus dem Gebirge, oder Die zween Antons ("The Foolish Gardener from the Mountains, or The Two Antons"), premiered in July 1789, and a series of five sequels.[11] Mozart himself enjoyed attending these comedies, as a letter to his wife Constanze attests.[12]

Viennese popular theater in this tradition often included improvisation, and there is evidence that Schikaneder may have improvised some of his part when he premiered the role of Papageno. For instance, when Mozart played a practical joke on him during his performance of "Ein Mädchen oder Weibchen", Schikaneder quickly went off-script and turned the joke to his own advantage. Mozart related the story in a letter to his wife:

Today I had such a yen to play the Glockenspiel myself I went on stage. Just for fun, at the point where Schikaneder has a pause, I played an arpeggio. He was startled, looked into the wings and saw me. When he had his next pause I played no arpeggio. This time he stopped and refused to go on. I guessed what he was thinking and again played a chord. He then struck the magic bells and said, "Shut up!" This made everyone laugh.[13]

The physical comedy that was an element of Viennese popular theater is called for directly at one point in the libretto. The opening eight bars of orchestral introduction to the duet "Pa pa pa", at the moment when Papagena is revealed to Papageno as his future wife, includes the stage direction that Papageno and Papagena "both engage during the ritornello in comic play."[14]

The experiences and background of the composer, who liked to have considerable input into the libretto (see The Abduction from the Seraglio for testimony), are also relevant.

• Mozart is known to have visited the Temple of Isis at Pompeii in 1769, just a few years after it was unearthed and when Mozart was himself just 13 years old. His visit and the memories of the site are considered to have inspired him 20 years later in his composition of The Magic Flute.[15]
• The play Thamos, King of Egypt by Tobias Philipp von Gebler, with themes similar to those in The Magic Flute, premiered in Vienna in 1774. Between 1773 and 1780, Mozart wrote incidental music, K. 345/336a, for this work.
