Many years ago there was a princess called Rhea, which was held prisoner by her uncle, so that she couldn't have babies that would take the throne afterwards.
Rhea escapes his uncle and has 2 babies with Mars the god of war.
His uncle finds out so he sends to guards to kill the 2 of them, as well as the babies.
I will name the city Rome, after me.
But the guards couldn't kill the babies so they sent them down the river. After a while they were found by a she-wolf which took them with a shepherd who adopted them.
At the end when they left their family they built a city, but in the moment to decide the name of the city, Romulus and Remus fought ending up in Romulus killing Remus.
After Romulus had killed Remus, he named the city Rome.
