The ancient Greeks had a large number of sea deities. The philosopher Plato once remarked that the Greek people were like frogs sitting around a pond—their many cities hugging close to the Mediterranean coastline from the Hellenic homeland to Asia Minor, Libya, Sicily and Southern Italy. Thus, they venerated a rich variety of aquatic divinities. The range of Greek sea gods of the classical era range from primordial powers and an Olympian on the one hand, to heroized mortals, chthonic nymphs, trickster-figures, and monsters on the other.
