Papgeno is the man (dressed like a bird) looking for a wife (her name is Papagena). So in this case he is the head character of this classical story.

This is een opera in two parts by Wolfgang Amadeus Mozart (an opera is play and instead of talking the actors sing). According to AI "(?)

was written by Emanuel Schikaneder, a close friend and collaborator of Mozart

I could not find this info back in the Dutch Wikipedia but I can imagine it's true and Wolfgang (Austrian) did the music.

All the best to you and thank you for showing interest.
