But Romulus neglected altogether to exact any satisfaction for the murder. Some writers say that the city of Lavinium, in its terror, delivered up the murderers of Tatius, but that Romulus allowed them to depart, saying that blood had been atoned for by blood. This speech of his gave rise to some suspicion that he was not displeased at being rid of his colleague. However, it caused no disturbance in the state, and did not move the Sabines to revolt, but partly out of regard for Romulus, and fear of his power, and belief in his divine mission, they continued to live under his rule with cheerfulness and respect. Many foreign tribes also respected Romulus, and the more ancient Latin races sent him ambassadors, and made treaties of friendship and alliance.
He took Fidenae, a city close to Rome, according to some authorities, by sending his cavalry thither on a sudden, and ordering them to cut the pivots of the city gates, and then unexpectedly appearing in person. Others say that the people of Fidenae first invaded the Roman territory, drove off plunder from it, and insulted the neighbourhood of the city itself, and that Romulus laid an ambush for them, slew many, and took their city. He did not destroy it, but made it a Roman colony, and sent two thousand five hundred Romans thither as colonists on the Ides of April.
XXIV. After this a pestilence fell upon Rome, which slew men suddenly without previous sickness, and afflicted the crops and cattle with barrenness. A shower of blood also fell in the city, so that religious terror was added to the people’s sufferings. As a similar visitation befell the citizens of Laurentum, it became evident that the wrath of the gods was visiting these cities because of the unavenged murders of Tatius and of the ambassadors. The guilty parties were delivered up on both sides, and duly punished, after which the plague was sensibly mitigated. Romulus also purified the city with lustrations, which, they say, are even now practised at the Ferentine gate. But before the plague ceased, the people of Camerium attacked the Romans, supposing that they would be unable to defend themselves on account of their misfortune, and overran their country. Nevertheless, Romulus instantly marched against them, slew six hundred of them in battle, and took their city. Half the survivors he transplanted to Rome, and settled twice as many Romans as the remainder at Camerium, on the Kalends of Sextilis. So many citizens had he to spare after he had only inhabited Rome for about sixteen years. Among the other spoils, he carried off a brazen four-horse chariot from Camerium; this he dedicated in the temple of Vulcan, having placed in it a figure of himself being crowned by Victory.
