Background information[]
Aeneas (pron.: /ɪˈniːəs/: Greek: Αἰνείας, Aineías, derived from Greek Αἰνή meaning "to praise") was a Trojan hero and half-god, the son of the prince Anchises and the goddess Aphrodite.
Aeneas had an extensive family tree. His wet-nurse was Caieta and he is the father of Ascanius with Creusa. Ascanius, also known as Iulus (or Julius), founded Alba Longa and was the first in a long series of kings. According to the mythology outlined by Virgil in the Aeneid, Romulus and Remus were both descendants of Aeneas through their mother Rhea Silvia, making Aeneas progenitor of the Roman people. Some early sources call him their father or grandfather, but considering the commonly accepted dates of the fall of Troy and the founding of Rome, this seems unlikely. The Julian family of Rome, most notably Julius Caesar and Augustus, traced their lineage to Ascanius and Aeneas, thus to the goddess Aphrodite. Through the Julians, the Palemonids make this claim. The legendary kings of Britain trace their family through a grandson of Aeneas, Brutus.
