 An autograph of the score is held at the Conservatorio di San Pietro a Majella in Naples.Since neither of the first two productions were supervised by Donizetti, it reflects changes made by other hands, which are evident from the differences in the two librettos and the presence of considerable non-autograph materials in the Naples score.There is also a score in the Ricordi Archives in Milan with significant autograph additions not found in the one in Naples.
