the goddesses of islands
The Nesoi (Greek Nῆσοι "islands"), in ancient Greek religion, were the goddesses of islands. Each island was said to have its own personification. They were classified as one of the Protogenoi, otherwise known as ancient elemental Greek primordial deities. The Nesoi were thought to have been Ourea who were cast under the sea during one of Poseidon's rages. (wikipedia) [This would suggest that the Nesoi are the female equivalents of the Ourea, the mountains... There were said to be only 10 Ourea in Greek mythology though, but if each island was represented by a Nesoi, then there would be hundreds of such goddesses. ]
In Greek mythology, the primordial deities are the first gods and goddesses born from the void of Chaos. In Orphic tradition, they are born from Chronos and Ananke. Hesiod's first (after Chaos) are Gaia, Tartarus, Eros, Erebus and Nyx. The primordial deities Gaia and Uranus give birth to the Titans and Aphrodite. The Titans Cronus and Rhea give birth to Zeus, Poseidon, Hades, Hestia, Hera and Demeter who overthrow the Titans. The warring of the gods ends with the reign of Zeus.
