POLYPHE was the Okeanid Nymph mother of Athena by Poseidon.
She appears to be closely related to several other water Nymphai which were variously called the mother of Athena, including the Okeanis Metis by Zeus (Olympian Athena), Halia by Poseidon (the Rhodian Athena), and Tritonis by Poseidon or Triton (the Libyan Athena).
Her name is similar in meaning to that of Metis, polyphê "of much thought", mêtis "of good counsel".
