Romulus & Remus
These twin brothers are the stars of Rome's most popular foundation myth.
Children of Mars (the Roman god of war) and Princess Rhea Silvia (a Vestal Virgin), Romulus and Remus were abandoned as infants by the river Tiber and nursed by a she-wolf. A shepherd and his wife raised the pair, but once they discovered their true heritage the brothers reclaimed power and established a new city.
But the brothers quarreled over the location of the site, and Romulus killed Remus to found Rome (named for himself) on the Palatine Hill.
