Were the operas Alcina and Giulio Cesare both written by George Frideric Handel?
Alcina Alcina (HWV 34) is an opera seria by George Frideric Handel. Handel used the libretto of "L'isola di Alcina", an opera that was set in 1728 in Rome by Riccardo Broschi, which he acquired the year after during his travels in Italy. Partly altered for better conformity, the story was originally taken from Ludovico Ariosto's "Orlando furioso" (like those of the Handel operas "Orlando" and "Ariodante"), an epic poem. The opera contains several musical sequences with opportunity for dance: these were composed for dancer Marie Sallé.
Il ballo delle ingrate Il ballo delle ingrate ("The Ballet of the Ungrateful Ladies") is a semi-dramatic ballet by the Italian composer Claudio Monteverdi set to a libretto by Ottavio Rinuccini. It was first performed in Mantua on Wednesday, 4 June 1608 as part of the wedding celebrations for Francesco Gonzaga (the son of Monteverdri's patron Duke Vincenzo of Mantua) and Margaret of Savoy. Both Vincenzo and Francesco Gonzaga took part in the dancing. Monteverdi also composed the opera "L'Arianna" (to another libretto by Rinuccini) and the music for the prologue to Guarini's play "L'idropica" for the occasion.
