Aeneas is considered:
half god and half mortal founder of the city that would become Rome
Step-by-step explanation:
The myth of Aeneas is derived directly from the myths and legends of the war of Troy when the Ionians of the time of the Asian minor kingdoms would lose the battle and it would be Aeneas who is able to escape the onslaught.
HE escapes and he founds the city that would later become Rome according to the legend.
He would also be in the myths made into a god like figure for the Romans which is only a partial truth and fabricated by Virgil in his epic.
