Der Stein der Weisen, oder die Zauberinsel (German for The Philosopher's Stone, or the Enchanted Isle) is a singspiel in two acts, jointly composed by Johann Baptist Henneberg, Benedikt Schack, Franz Xaver Gerl, Emanuel Schikaneder, and Wolfgang Amadeus Mozart in 1790.
[2] The text is based on a fairy tale from Christoph Martin Wieland's Dschinnistan [de], published in the late 1780s.
American musicologist David Buch announced the discovery of a Viennese score with attributions to all five composers.
[7] The autograph of "Nun, liebes Weibchen" (K. 625/592a/Anh.A 64) is held by the Bibliothèque Nationale in Paris; the rest of the original score is lost.
[3] The singspiel was premiered on 11 September 1790 in the Theater auf der Wieden, conducted by Henneberg.
