Romulus and Remus
The twin sons of Rhea Silvia and Mars. They were, together with their mother, cast into the Tiber. The god Tiberinus saved Rhea Silvia from drowning, and the brothers were miraculously rescued by a she-wolf. The wolf reared the twins together with her cubs underneath a fig tree (the 'ruminalus ficus'). After a few years they were found by the shepherd Faustulus, who took the brothers home and gave them to his wife Acca Larentia to raise.
When they reached maturity they killed Amelius, the brother of their grandfather, and built a settlement on the Palatine Hill. During a quarrel where Remus mocked the height of the walls, Romulus slew Remus and became the sole ruler of the new Rome, which he had named after himself. He took Hersilia as his wife.
To enlarge his empire, he allowed exiles and refugees, homicides and runaway slaves to populate the area. The shortage of women he solved by stealing Sabine women whom he invited to a festival. After a few wars, the Sabines agreed to accept Romulus as their king. Upon his death he was taken to the heavens by his father Mars. He is later revered as the god Quirinus
