Aphrodite vs Venus

Are Aphrodite and Venus the same goddess? In myth, yes — Venus caught with Mars, Venus mother of Aeneas, Venus wounded by Diomedes are all Aphrodite's stories in Latin. In what the name is for, no — Virgil's Venus is the ancestress of Rome who pleads for "empire without end", and Ovid's Venus deifies Julius Caesar; Livy knows an altar of Venus Murcia. Nothing Greek does that.
