Psamathe, which translates loosely into 'sand goddess,' is a figure of Greek Mythology appearing mostly in Ovid's Metamorphoses and Hesiod's Theogony. Daughter of the sea god, Nereus, and the Oceanid, Doris, this Nereid had three children: Phocus, Theoclymenus and Theonoe.

Phocus is named after the Greek word for seal, 'phoke,' for an interesting reason. When his mom and dad, Aeacus, first met, she turned into a seal to try to avoid having sex with him. However, he knocked her up anyway, prompting the name of their son and a kind of creepy bestiality site on the internet.

Unfortunately, Phocus was later killed by his half brothers Peleus and Telamon. In response, Psamathe sent a huge wolf after them, but this was turned to stone when her sister, Thetis, stepped in and saved Peleus. (it still managed to take out a herd of cattle)

Some time later, Psamathe married Proteus, the king of Egypt. This union produced Theoclymenus and Theonoe.

Psamathe also had a part to play when Poseidon and the sea gods fought with Dionysus, offering up the plea to Zeus that ended the battle.
