This is a ca. 1762 copy of the libretto of "Ifigenia in Aulide," by Vittorio Amedeo Cigna-Santi, the principal librettist at the Teatro Regio in Turin. Cigna-Santi's libretto is an adaptation of Euripide's story of Ifigenia, the daughter of the king of Argos, Agamemnon. The goddess Diana decreed that Ifigenia had to be sacrificed in order to guarantee fair winds for the king's fleet on their journey to Troy. Achilles, rushed to save Ifigenia, his wedding bride, but Diana, moved by Ifigenia's obedience, spared her life before the priest killed her. Ferdinando Giuseppe Bertoni set this libretto to music for the 1762 carnival season in Turin. According to scholar George Hollis, the surviving arias of Ifigenia in Aulide are technically demanding and contain florid and lengthy passages in the tradition of opera seria. The library's copy of "Ifigenia in Aulide"is bound with the following librettos: "Catone in Utica," by Pietro Metastasio; "Sofonisba" by Mattia Verazi; "Arianne e Teseo" by Pietro Pariati; and "Le piacevoli poesie" by Gasparo Gozzi.

This three-act opera was premiered at the Comédie Italien on 22 November 1762.
