Romulus and Remus had a poor start in life. But look at them now. One is the ruler of Rome, the other is dead – or immortal.
Romulus and Remus leave their sheep farm to found a new city, Roma. When Remus is killed, Romulus rules on his own, but he quarrels with the senate who represent all the people who have come to populate Roma. When the senate plots to overthrow him, Romulus appeals to the god who claimed the body of Remus to help him. The god does, with unexpected results.
Romulus and Remus, adopted children of Laurentia and Faustulus, are shepherds until they discover they are the grandchildren of Numitor, the deposed ruler of Alba. They kill the usurper and restore Numitor to his throne but leave Alba to found their own city.
They are aided in this by their old friends, Hostius, Spurius and Lucius, and others who see the advantage of taking part in the founding of a new city. When Remus dies and Romulus takes his body to the temple, he is charge by the god to complete the task of founding the city. Romulus returns to build and then rule the new city, Roma, with guidance from the elected senate, who represent all the people who come to settle in the city.
Lacking women, the men of Roma kidnap some Sabine girls to be their wives, but make a truce with Titus Tatius, the Sabine leader. Romulus marries Hersilia, Titus’s sister, and Romulus and Titus rule Roma together. However, Titus is killed settling a family dispute and the senate, fearing Romulus’s power, attempt to depose him. Refusing to let Spurius and Lucius and the army fight the senate on his behalf, Romulus goes alone to the temple where once a god appeared and took away the body of his brother. He appeals to the god for release from his task.
