The best atheistic manifesto

Beside the Gobbi’s fantastic performance, think about the shocking effect on XIX public from verses as “E credo l’uom gioco d’iniqua sorte, dal germe della culla al verme dell’avel.” (And I believe that man is the toy of treacherous fate, from the seed in the cradle to the worms of the grave.)
No doubt, the best atheistic declaration in opera’s history…:-)
