Dione, whose name means Divine or Goddess, is mainly known as Aphrodite’s mother, but she had her own cult, centred around the oracle at Dodona. She was probably a Mycenean goddess, but her origin is somewhat mysterious.
Athena is famous for many things, but her birth, springing fully formed from her father’s head, is a well-known part of her myth, depicted on blackfigure vases from early Greece and mentioned by Homer and Hesiod. Her mother, Metis, is less well-known, although it was she who actually gave birth to Athena, inside Zeus’ belly.
Human rulers die, and the next generation takes over. Sometimes the older generation gets “helped” off the throne, either by assassination or war. So it’s not surprising that mythology has many versions of this succession story, which rarely involve peaceful inheritance.
Now, ask what the reason is for my pride, and then dare to prefer Latona to me, that Titaness, daughter of Coeus, whoever he is. Latona, whom the wide earth once refused even a little piece of ground to give birth on.
(Latona is the Roman name for Leto.) Even in her great access of hubris, the only thing Niobe could say of Coeus/Koios was that no one knew who he was. A quick look at online guides to Greek myth shows that Koios is by no means famous now, but there seems to be a desire to fill out his dossier.
The Norse sea-god – if he reminded you of anyone in the Graeco-Roman pantheon, wouldn’t it be Neptune/Poseidon? And yet, when the medieval Icelanders were copying out Greek myths, they explained the god Saturn/Kronos to their readers as “Njord”. What did the two have in common, that Njord would stand for Saturn to an Icelander?
The family of the sun-god Helios features many minor goddesses of sun and light. Helios is the main god of the sun; his name, and his resemblance to many Indo-European sun-gods and goddesses puts that out of doubt, but it is interesting how solar females cluster around him.
Some of these goddesses may well have had their own solar cults long ago, but it’s impossible to verify now. Two of them were his mother and aunt, the other was his daughter. (Helios’s lineage also includes the witches Circe and Medea, as well as Hecate, a grand-daughter in some versions of her family tree.)
