Like all ancient societies, the Romans possess an incredibly heroic founding story.
What made the Romans different is that they created two distinct creation myths for themselves.
In the first they are said to be descended from the royal Trojan refugee Aeneas, (son of the goddess Venus).
While in the second it is said that the city of Rome was founded by Romulus, the son of an earthly princess and the God Mars.
The story of the first legend
Romulus founds Rome, according to tradition, becoming the first Roman king. The story of Romulus, his twin brother Remus, and the founding of Rome is one of the most popular legends about the Eternal City, which tells how the God Mars united with the virgin Rhea Silvia, the daughter of a deposed king.
From this union Romulus and Remus were born at the same time; and the king ordered the twins to be thrown into the river Tiber.
When the basket with the two babies got stuck in the bushes near the shore a shepherd found them and fed them until the shepherd Faustulus took them to his home. When they grow up, Romulus and Remus learn that they were the sons of Mars and Rhea, as well as the prophecy that they were destined to have their own city - this is where the rivalry was born; Romulus kills his brother and the city takes his name, Rome.

The second legend
But there is another legend about the creation of Rome: At the end of the Trojan war, the city was destroyed, the men were killed, the women became slaves, some Trojans were able to escape, among them Prince Aeneas, the son of the Goddess Venus and the man Anshiu.
While Troy was burning, Aeneas left the city, with his son, Ascanus, and their followers. After many adventures and hardships, the Trojans arrive at Laurentum on the west coast of Italy, where Aeneas marries Lavinia, daughter of the local king, Latinus, and founds the city, which he named Lavinium, in honor of his wife.
While Askani, son of Aeneas, decided to build a new city, he called it Alba (Longa) and the nearby mountain, Alban - Rome would be built nearby.
But who is the founder of Rome - Romulus or Aeneas?
Cato, historian, philosopher, at the beginning of the second century BC, accepts the idea of Eratosthenes that between the foundation of Rome (8th century BC) and the fall of Troy (12th century BC) there are 400 years - 16 generations - and he combined the the two stories to come up with what is the accepted version, where Romulus may not be the grandson of Aeneas, the son of Ascanus, but at least appears to be a distant descendant of the Trojan hero.
Chosen people
Both myths helped establish the Romans as God's chosen people, tracing their origins back to Troy and the Hellenistic world.
Roman tradition indicates that it was Romulus' hometown, the Palatine Hill, in which what was called "Year 1" (or 753 BC in the Western Christian calendar) was recorded.
Archaeological excavations on the hill have found pieces dating back to at least 1000 BC.
