After a woman was killed for loudly mourning the death of her fiancé, a man from this city, the murderer was forced to pass under another city's “Sister's Beam.” A god prophesied that this city would be founded 30 years after the discovery (-5[1])of a sow surrounded by 30 piglets. After a leader of this city attempted to play both sides in a battle involving Fidenae (15[1])and was torn apart by chariots, this city was destroyed. Three wounded warriors from this city were picked off by (*) Publius to conclude a duel suggested by this city's dictator Mettius Fufetius. A king of this city (10[1])named Amulius overthrew his brother Numitor and sought to force celibacy on Numitor's daughter Rhea Silvia. (10[1])Ascanius founded this city, and Romulus and Remus descended from its royal family. For 10 points, name this early rival of Rome. (10[1])■END■ (0[1])
