Besides the two above mentioned operas of Mozart [Don Giovanni and Die Zauberflöte], I experienced a third ordeal in a new popular-opera, with music by Hummel, which by a singular chance such as will assuredly never occur again, went through a long succession of nightly representations. It was called “Princess Eselhaut” and as far as the author’s text, was so wretched a piece of patchwork, that in spite of the pretty music of which five or six of the Numbers were received with great applause, it was at the conclusion unanimously hissed. This according to Vienna custom at once consigned it to the tomb. Hummel who conducted, had, already, quite resignedly expressed himself to me, who in honour of him led as first violin. “Another pure labour in vain!” But on the following evening when another piece was to have been announced, it could not be given, owing to the illness of several performers in the opera and play, and the manager was therefore obliged to repeat the condemned opera though at the risk of exciting an uproar in the theatre. On that evening nevertheless, just on account of the anticipated tumult, the theatre was crammed to excess, and the piece was hissed at the end of each act, and again at the conclusion. But the musical pieces met with more applause than on the first night, and at the fall of the curtain when the hissing had ceased, the composer was even called for, and greeted with vehement applause.
