Long and long ago, it is said, Nimitur, King of Alba, was robbed of his crown, and thrust from his kingdom by his younger brother, Amulius. Now Nimitur had one daughter. Amulius, when he had made himself king, forced this maiden to become a "Vestal", - that is to say, a high priestess, and, as a Vestal, she had to make a vow never to marry. This Amulius did in order to reign in safety, for he was afraid if the daughter of Nimitur were to marry that her children might some day try to win back their rightful inheritance. However, his cunning plan failed: the maiden was loved by the god Mars; she broke her vow, and Romulus and Remus were born.
