I give Solera a lot of credit. Smart guy! Sometimes the words of an opera libretto are not really all that important, but in this case they are. Nabucco is based on the Bible, and the words of the most famous passage, the chorus of the Hebrew slaves, “Va, pensiero,” come from Psalm 137. “By the waters of Babylon we sat and wept; on the willows there we hung up our lyres.” When the opera was first performed, that piece was understood as being about Italy. But today, when we listen to it, it’s Zionist. They want to return to Zion.
