Phorkys Mosaic Bardo.jpg
Late Roman mosaic from the Trajan Baths of Acholla, showing three aquatic deities: Phorcys (middle) and Ceto (right). Bardo National Museum, Tunis.

He and his wife Ceto were also gods of the largest of sea creatures. Ceto‘s name means “whale” or “sea-monster” and Phorcys’ perhaps means “seal” (phokes in Greek).

Their children were dangerous sea-monsters: Scylla, a monster who devoured passing sailors, Thoosa, mother of the rock-tossing Cyclops Polyphemus, Ladon, a hundred-headed sea-serpent, Echidna, a she-dragon, the Graeae, spirits of the sea-foam, and the Gorgons, whose petrifying gaze probably created the dangerous rocks and reefs of the sea.
