Cerdo (mythology)

In Greek mythology, Cerdo (Ancient Greek: Κερδοῦς means 'gain, profit' or 'the wily one' or 'weasel, vixen') was the nymph-wife of King Phoroneus of Argos and mother of Apis and Niobe. Otherwise, the consort of Phoroneus was called either Cinna, or Teledice (or Laodice) also a nymph, or Perimede, or Peitho and Europe.

According to Graves, Cerdo (‘gain or ‘art’) is one of Demeter's titles; it was applied to her as weasel, or vixen, for both are considered prophetic animals.
