La Didone is an opera by Francesco Cavalli, set to a libretto by Giovanni Francesco Busenello (later librettist for Claudio Monteverdi). The opera was first performed at Venice's Teatro San Cassiano during 1641. The plot is based on Virgil's Aeneid (Book 4 in particular), though Busenello, in his second libretto for Cavalli, replaces Dido's tragic suicide of Virgil with a happy ending in which Dido marries Iarbas, King of the Getuli, who saves Dido from herself after Aeneas abandons her. The action is divided into a prologue and 3 acts. Preceded by a solemn prologue in which Iride admonishes mortals that they should not offend the gods, the story of Cavalli’s Didone comes to life thanks to numerous solo passages of highly varied character and structure, designed both for simple basso continuo support and for a more complex instrumental accompaniment, for five real parts which enjoy some independent moments and which create a diversion from the action or blend in with it in a wholly logical way, intensifying it in a studied, evocative manner. The tragic story of the Carthaginian queen is thus unfolded with extreme attention in a framework that had already been adopted by Monteverdi, of whom Cavalli is considered a worthy successor. In this case it is enlivened and, we might say, given a more popular, direct appeal as it aims to communicate with a public that is gradually expanding. The composer is sincere when he states: ”My spirit has always been far from the printing press: I have preferred to allow my weaknesses to run where fortune takes them with the pen rather than the press.” He identifies with the torment of Didone and with the ”force of nature” (Prunières) that is his and the brilliance of some of his solutions, he creates one of the most tragic, tormented operas of the entire seventeenth century.
