and changed the words in "Ah, se d'amor potessi". Furthermore, an aria for the tenor "Se crudel cosi m'estimi" was added without Donizetti's consent. Nevertheless the lyrics were later recycled by Donizetti for a tenor aria added to the January 1834 production at the Teatro Regio di Torino. In 1833, Fausta was performed at La Fenice in Venice, with Giuditta Pasta as Fausta and Domenico Donzelli as Crispo receiving mixed reviews. For this occasion Donizetti added a new scene at the beginning with a new aria for Fausta and, in act 2, a new duet "Per te rinunzio al soglio" for Fausta and Crispo. This duet was later utilized for Buondelmonte and ultimately in Maria Stuarda for the Milanese premiere of this opera as a duet for Maria and Leicester, "Ben io comprendi"; later, in 1865 for a Naples production the words were changed to those used ever since: "Da tutti abbandonata". Additionally, for the Venice production Donizetti wrote a duet (act 2) for Costantino and Crispo, "T'amo ancora" replacing the baritone's aria "Se di regnar desio"; and finally, a tenor's aria (also in act 2) "Ah! perche dirmi crudel". In 1841, for a La Scala production, Donizetti added a duet for tenor and baritone, "E che mi valse...", borrowing from earlier operas Pia de Tolomei and Il diluvio universale. Other important premieres include Madrid in 1833, Lisbon and Barcelona in 1834; Palermo, Genoa and Bologna also in 1834; Berlin in 1835; Havana in 1837; Vienna in 1841; London in 1841 (described as a "failure"); and Rio de Janeiro in 1850. The opera received its first performance in modern times when it was revived at the Rome Opera in 1981 with Raina Kabaivanska in the title role. Roles Synopsis Time: 326 A.D.
