Die Zauberflöte was staged for the first time in Vienna on 30 September 1791 and was a tremendous success.  Between then and Mozart's death on 5 December, the Viennese publishers Artaria and Kozeluch competed to bring out the most popular numbers, with Artaria first off the mark.  However, Kozeluch's contemporary edition is more complete, comprising thirty-eight numbers to Artaria's twenty-four. Of these, some twenty-six are first editions--they are either contemporary with Artaria or those numbers are absent from Artaria's edition. 'Bey Männern' (no.7), and 'In diesen Heil'gen' (no.22) appeared on 26 November 1791 and 'Seyd uns zum zweytenmal willkommen' on 3 December, all before Mozart's death (see Haberkamp, p.360).  This copy contains some interesting alternative texts to 'Bewahret euch' ("Doch unheil die Warnung traute Männer", which is ascribed to H. Dr Schülze), to 'In diesen heil'gen Mauern' (provided with two new texts, one ascribed to Mahlmann, and with the opening line corrected to "...Hallen"), and to 'O Isis und Osiris' ("O Vater! unser Vater sieh' die Deinen").
