 Jeremy Commons, however, points out that Wiklund discovered that in Donizetti's autograph score in the Naples Conservatorio di Musica San Pietro a Majella the overture is clearly dated 1828.Commons notes that the opera's style fits better with florid operas of the 1820s such as "Gianni di Calais" than with the more romantic 1830s operas such as "L'elisir d'amore", and Wiklund suggests that Neapolitan elements in the opera indicate that it was composed in Naples where Donizetti was active in the 1820s.A further score of 1832, with some revisions by the composer (including the omission of the Neapolitan elements), is located in the Casa Ricordi archives in Milan.
