The never completed cantata (for tenor, three-part male choir, and orchestra) was probably written in Vienna during the first half of 1783: "only the first choir and the tenor aria are completed in the score draft; enough of the orchestration is sketched to be easily completed" (cf. Köchel). It was probably composed for a masonic purpose, but before Mozart joined the lodge, and not for a private function. The location of the composer's autograph is unknown since it was apparently sold to a U.S.
collector in the 1930s; a manuscript copy, split up by Karl Mozart, is kept at the Salzburg Mozarteum and at the Glasgow University Library. "The Mozarteum owns a complete score of the first choir and part of the first aria, from the estate of Mozart's son and written in his hand" (cf. Jahn II³, S. 111). The piano arrangement was in all likelihood originally prepared by abbé Maximilian Stadler. Stadler's ms. (2 pp. on a single leaf) is now kept at the Széchenyi National Library, Budapest, and is captioned by Georg Nikolaus Nissen, who organised Mozart's nachlass with Stadler in 1798/99: "Freymaurer-Cantate: Dir Seele des Weltalls etc. von Mozart. Fürs Clavier ausgezogen von N. N." This piano reduction of the choir only "is deftly done and, with very minor exceptions, is true to the original [...] No voices are included. The handwriting is exactly the same at in the four-voice choir arrangement, so there can be no doubt as to the identity of the writer" (cf. Krit. Bericht d/28). The present manuscript however, encompassing the same music, is penned by Mozart's youngest son Franz Xaver Wolfgang (known throughout his lifetime as "W. A. Mozart Sohn") and is very likely based on Stadler's arrangement. It resembles the Budapest sheet in bearing Nissen's later caption: "Arie aus der von Mozart unvollendeten Freymaurercantate, für Clavier ausgezogen von N. N." On the reverse, after the end of the notes, there is a ms. attribution by Ludwig Carl Seydler: "Handschrift von W. A. Mozart (Sohn)", along with his stamp ("Lud. C. Seydler in Graz / Domorganist") and F. X. W. Mozart's dated in pink ink. In recognition of his discoveries of Mozart autographs in Styria, Seydler was made an honorary member of the Mozarteum in 1868 (cf. ÖBL XII, 207)..
