Is Venus the same goddess as Aphrodite?

Romans identified Venus with Aphrodite and adopted her core mythology, including her motherhood of Aeneas by the mortal Anchises. What Rome added was political: Aeneas's descendants were said to found Rome, giving Venus a specific genealogical and civic role in Roman identity that Aphrodite, worshipped across many independent Greek cities, never had in a comparable form.

Why did Julius Caesar build a temple to Venus Genetrix?

Caesar's family, the gens Iulia, claimed descent from Aeneas's son Iulus and therefore from Venus herself. Vowing a temple before the Battle of Pharsalus, Caesar ultimately dedicated it to Venus Genetrix, "Venus the Mother," rather than to Venus Victrix as first planned, formally placing his family's divine ancestry into Roman public religion as part of his new forum, dedicated in 46 BCE.

How is Venus the ancestor of Julius Caesar's family?

The chain runs through Aeneas: Venus and the mortal prince Anchises had a son, Aeneas, who escaped the fall of Troy and eventually settled in Italy; his own son, Iulus (also called Ascanius), was understood as the direct ancestor of the gens Iulia. This made Julius Caesar and, later, Augustus descendants of the goddess by a documented mythological genealogy rather than by loose poetic association.

What is the difference between Venus Genetrix and Venus Victrix?

Venus Genetrix, "Venus the Mother" or "the Ancestor," emphasizes her role as progenitor of the Julian line through Aeneas; Venus Victrix, "Venus the Victorious," emphasizes her patronage of military success, worshipped most visibly at the theater complex Pompey the Great built and dedicated nominally in her honor. Both titles could apply to the same goddess depending on which political or religious purpose a dedication served.

Does Aphrodite have the same political role in Greek religion?

No. Aphrodite was widely worshipped across Greek cities as a goddess of love and beauty, but no major Greek city or family built a comparable public claim to literal descent from her the way Rome's Julian family did through Venus and Aeneas. The ancestor-goddess role is a specifically Roman development layered onto shared Greek mythology.
