Greek and Roman Mythology

And am I not right in asserting that there are two goddesses? The elder one, having no mother, who is called the heavenly Aphrodite--she is the daughter of Uranus; the younger, who is the daughter of Zeus and Dione --her we call common; and the Love who is her fellow-worker is rightly named common, as the other love is called heavenly. All the gods ought to have praise given to them, but not without distinction of their natures; and therefore I must try to distinguish the characters of the two Loves. Plato, Symposium

Pausanias (9.16.3) writes about 3 versions of Aphrodite:

At Thebes are three wooden images of Aphrodite, so very ancient that they are actually said to be votive offerings of Harmonia, and the story is that they were made out of the wooden figure-heads on the ships of Cadmus. They call the first Heavenly, the second Common, and the third Rejecter. Harmonia gave to Aphrodite the surname of Heavenly to signify a love pure and free from bodily lust; that of Common, to denote sexual intercourse; the third, that of Rejecter, that mankind might reject unlawful passion and sinful acts.

Near the well is a hall of Dionysus and a sanctuary of Black Aphrodite. This surname of the goddess is
simply due to the fact that men do not, as the beasts do, have sex always by day, but in most cases by night. Pausanias
