The original in German language is now lost. During the composer's lifetime up until today in Croatia it has been performed in Croatian language. As Zaytz was a native Italian speaker, that is it was his maternal tongue he had learned in the streets of his native town Fiume (whereas German language he had been learning in school by formal obligation), he decided to publish a Croatian-Italian edition of the opera in question, with assistance of Gian Paolo di Carminati.
