Gioielli del Madonna

I gioielli della Madonna (English: The Jewels of the Madonna) is an opera in three acts by Ermanno Wolf-Ferrari to an Italian libretto by Carlo Zangarini and Enrico Golisciani, based on news accounts of a real event.
It was first performed at the Kurfürstenoper, Berlin, 23 December 1911 under the title Der Schmuck der Madonna. That performance was in German, but now it is usually given in Italian. (Wolf-Ferrari stated that his operas were often first given in German simply because he had a German publisher.)
