S.Hertig; Zurich University Collection.Sea monster, familiar of sea deities - notably Poseidon and Thetis (one of her mutations in the fight with Peleus) - but also becoming a popular decorative motif. It is a creature set by Poseidon to devour Hesione and Andromeda, but killed by Herakles and Perseus respectively. In early art it resembles a lion-fish (a shark?) but from the 5th century has a pointed muzzle (like a crocodile) with long ears, gills and a long fishy body, sometimes with lion forelegs but usually flippers. In late art it is used to signify Jonah's whale.
