[ The recitative and these two passages are omitted from the autograph score, which prevents any identification of the alterations. In "Idomeneo" the Oracle is accompanied only by trombones and horns. Gugler throws doubt on the anecdote (Morgenbl., 1865, No. 33, p. 777).]

[ At the wedding festivities in Vienna, on October 1, Martin's "Arbore di Diana" was performed (Wien. Ztg., 1787, No. 79, Anh.), and was repeated nine times in the same year.]

[ Wien. Ztg., 1787, No. 84. "Don Giovanni" was to have been played for the first time on this occasion, and Sonnleithner informs me that a book of the words had actually been printed, with the title-page, "Da rappresentarsi nel teatro di Praga per l'arrive di S. A. R. Maria Teresa, Archiduchessa d' Austria, sposa del Ser. Principe Antonio di Sassonia l'anno 1787." Here the first act closes with the quartet (8); the second act is intact. The performance did not take place, the Princess leaving Prague on October 15.]

[ In Mozart's Thematic Catalogue the subject of the overture is entered under date October 28, with the title, "Il Dissoluto Punito, o il Don Giovanni: Opera buffa in 2 Atti—Pezzi di Musica 24." The overture is, as usual, written as a separate piece, hastily, but with scarcely any alterations.]
