Cerdo (mythology)
In Greek mythology, Cerdo 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 also a nymph, or Perimede, or Peitho and Europe.
According to Graves, Cerdo is one of Demeter's titles; it was applied to her as weasel, or vixen, for both are considered prophetic animals.
