Ercole su'l Termodonte (Italian pronunciation: [ˈɛrkole sul termoˈdonte]; Hercules in Thermodon) is a baroque Italian opera in three acts. In 1723, it became the sixteenth opera set to music by Antonio Vivaldi. Its catalogue number is RV 710. The libretto was written by Antonio Salvi (not Giacomo Francesco Bussani as previously misattributed). The opera was premiered January 23, 1723 in Rome's Teatro Capranica. Due to a papal edict preventing women from appearing onstage in Rome, it premiered with castrati singing all the female roles. Vivaldi was both conductor and solo violinist.
