Spartacus

Act I
The Roman consul Crassus returns to Rome from his latest conquests in a triumphal procession. Among his captives are the Thracian king Spartacus and his wife Phrygia. Spartacus laments his captivity and bids a bitter farewell to Phrygia, who is taken off to join Crassus’ harem of concubines. To entertain Crassus and his entourage, Spartacus is sent into the gladiatorial ring and is forced to kill a close friend. Horrified at his deed, Spartacus incites his fellow captives to rebellion.
Act II
The escaped captives celebrate their freedom. Meanwhile, Crassus entertains the Roman patricians with lavish entertainment. Spartacus and the other escaped captives disrupt the orgy and rescue the slave women, including Phrygia. Aegina insists that Crassus pursue the slave army immediately. The lovers celebrate their escape to the "Adagio of Spartacus and Phrygia".
Act III
Aegina discovers Spartacus’s camp and observes the lovers emerging from their tent the next morning. Aegina sends word to Crassus, who sends his army in pursuit. Internecine struggles break out among Spartacus’s forces. Finally, Crassus’s forces discover Spartacus and impale him upon their spears. Spartacus’s closest followers recover his body and carry it off while Phrygia mourns her loss.
