Question: Which opera was produced first, Nabucco or Il prigioniero?
Sentence (from "Nabucco"): The libretto is based on biblical books of Jeremiah and Daniel and the 1836 play by Auguste Anicet-Bourgeois and Francis Cornue, although Antonio Cortese's ballet adaptation of the play (with its necessary simplifications), given at La Scala in 1836, was a more important source for Solera than the play itself.
Relevant evidence: No
