Romulus and Remus

These mythological creations, Romulus and Remus are known as the founders of Rome. According to legend, they were born at a time when they would have been the nation's rightful leaders, and overthrown the person ruling at the time. A servant was ordered to kill them, but instead sent them down a river in a basket. They were raised by a wolf, Luna, and found when they were infants by a shepherd.
According to another legend, Romulus and Remus were children of Hercules , and the shepherd saved them after they were thrown into the Tiber River to replace his child that had died. Regardless of their origins, Romulus and Remus grew to be great... although one of them found that it couldn't last.
The other main origin of Romulus and Remus is the one that they were Mars' children, and that their mother was a priestess who was not allowed to marry.
When the twins decided that they wanted to found a city, they went to the place their adoptive father (the shepherd) found them. Romulus built a wall, and Remus started jeering at him, saying that it couldn't keep anyone out. Romulus hit him with a shovel and killed him, and became the sole ruler of his new found city, Rome.
