. . . and so soon as he had cut off the members with flint and cast them from
the land into the surging sea, they were swept away over the main a long time:
and a white foam spread around them from the immortal flesh, and in it there
grew a maiden. First she drew near holy Kythera, and from there, afterwards, she
came to sea-girt Kypros, and came forth an awful and lovely goddess, and grass
grew up about her beneath her shapely feet. Her gods and men call Aphrodite, and
Aphrogeneia (the foam-born) because she grew amid the foam, and Eustephanos
(well-crowned or girdled) Kythereia because she reached Kythera, and Kyprogenes
because she was born in billowy Kypros, and Philommedes (Genital-Loving) because
sprang from the members. And with her went Eros (Love), and comely Himeros
(Desire) followed her at her birth at the first and as she went into the
assembly of the gods.
The first Venus [Aphrodite] is the daughter of Caelus [Ouranos] (Sky) and Dies [Hemera] (Day); I have seen her temple at Ellis. The second was engendered form the sea-foam, and as we are told became the mother by Mercurius [Hermes] of the second Cupidus [Eros]. The third is the daughter of Jupiter [Zeus] and Dione, who wedded Vulcanus [Hephaistos], but who is said to have been the mother of Anteros by Mars [Ares]. The fourth we obtained from Syria and Cyprus, and is called Astarte; it is recorded that she married Adonis.
