Ascanius was succeeded by his son Silvius, who by some chance had been born in the forest. He became the father of Aeneas Silvius, who in his turn had a son, Latinus Silvius.
He planted a number of colonies: the colonists were called Prisci Latini. The cognomen of Silvius was common to all the remaining kings of Alba, each of whom succeeded his father.
Their names are Alba, Atys, Capys, Capetus, Tiberinus, who was drowned in crossing the Albula, and his name transferred to the river, which became henceforth the famous Tiber. Then came his son Agrippa, after him his son Romulus Silvius. He was struck by lightning and left the crown to his son Aventinus, whose shrine was on the hill which bears his name and is now a part of the city of Rome.
He was succeeded by Proca, who had two sons, Numitor and Amulius. To Numitor, the elder, he bequeathed the ancient throne of the Silvian house. Violence, however, proved stronger than either the father's will or the respect due to the brother's seniority; for Amulius expelled his brother and seized the crown.
Adding crime to crime, he murdered his brother's sons and made the daughter, Rea Silvia, a Vestal virgin; thus, under the pretence of honouring her, depriving her of all hopes of issue.
But[*](THE STORY OF ROMULUS. Birth and Uprearing.) the Fates had, I believe, already decreed the origin of this great city and the foundation of the mightiest empire under heaven.
The Vestal was forcibly violated and gave birth to twins. She named Mars as their father, either because she really believed it, or because the fault might appear less heinous if a deity were the cause of it.
