neas of Troy, coming to the land of Italy, took to wife Lavinia, daughter of King Latinus, and built him a city, which he called Lavinium, after the name of his wife. And, after thirty years, his son Ascanius went forth from Lavinium with much people, and built him a new city, which he called Alba. In this city reigned kings of the house and lineage of neas for twelve generations. Of these kings the eleventh in descent was one Procas, who, having two sons, Numitor and Amulius, left his kingdom, according to the custom, to Numitor, the elder. But Amulius drave out his brother, and reigned in his stead. Nor was he content with this wickedness, but slew all the male children of his brother. And the daughter of his brother, that was named Rhea Silvia, he chose to be a priestess of Vesta, making as though he would do the maiden honour; but his thought was that the name of his brother should perish, for they that serve Vesta are vowed to perpetual virginity.
