Calliroe is an opera by Antonio Sacchini, set to a libretto by Mattia Verazi. It was first performed in Ludwigsburg on 11 February 1770 and the ballets were set by French choreographer Louis Dauvigny.
The opera follows the usual pattern of opera seria of the time: secco recitative interlaced with da capo arias. Within this format Sacchini introduced strong dramatic music to suit the libretto: stromentato recitative is also used for extra dramatic effect, and the arias are sometimes interrupted by bursts of recitative. Stylistically, the work is thought to anticipate Italian opera of the following decade, and in particular Mozart's Il re pastore.
Calliroe is a melodramma eroico or opera in 2 acts and 23 scenes by composer Giuseppe Farinelli. The work uses an Italian language libretto by Gaetano Rossi. The work premiered at La Fenice in Venice on 3 January 1808 in a double bill with the house premiere of Urbano Garzia's ballet Il calunniatore punito ossia Il conte Lenosse.
