regie rigor
Cher public, you are simply getting too clever for this poor old simple-minded doyenne. With only two photos to guide you, so many of you deduced that the opera was Wagner’s Siegfried, in the new production by Sven-Eric Bechtolf for Vienna.
And so, our next quiz will be limited to only one photo. Should you not be able to guess agree on the opera, La Cieca will oblige with additional images — though, given the demonstrated intelligence level of the regulars here, further clues will almost certainly not be necessary only add to the fun!

The Oliympia portion of “Tales of Hoffman”(except who would all those men be?)
either that, or an operatic rendition of “I only have eyes for you?”
Salome
I guess Die Zauberfloete…the chorus of priests at the opening of Act 2….the eye is a Masonic symbol also so that would fit
Looks like conspiratorial happenings, so I’m guessing Ballo.
Zauberflöte also makes sense.
The Rake’s Progress.
But is it the brothel scene or the asylum scene?
How about Lulu? Loadsa letching men…
I was going to say Cenerentola, but I think Zauberflote makes more sense.
(How do I type umlauts???)
1984 – those eyes represent Big Brother watching us.
My guess is Die Zauberfloete.
The caption “regie rigor” reminds me of one of my favorite arias, “Di rigori armato,” so I’m going to guess Der Rosenkavalier even though I have no idea what scene the picture could represent.
