Venus was the Roman goddess of love and the mother of the Trojan hero Aeneas.
In Roman mythology, Venus was the divine mother of Aeneas through her relationship with the Trojan prince Anchises. Aeneas survived the destruction of Troy, travelled west, and became the legendary ancestor of the Roman people. This genealogy gave Rome a prestigious connection to the heroic world of Troy.
The story became especially influential through Virgil’s Aeneid, which presents Venus as Aeneas’s protector and adviser. She intervenes on his behalf, helps guide him toward Italy, and supports the destiny that will eventually lead to Rome. Julius Caesar and the Julian family further promoted the claim that they descended from Venus through Aeneas.
Venus was closely identified with the Greek Aphrodite, but her Roman worship also emphasized fertility, prosperity, victory, and the state’s ancestry. Diana was associated with the hunt, Minerva with wisdom and crafts, and Juno with marriage and queenship, so none is the canonical answer here.
