Scylla was a monstruous, evil creature of the seas. According to a myth, she was loved by Poseidon, the God of the Sea, and so his jealous wife Amphitrite changed her into a monster with a cat's tail and dogs’ heads wrapped around her waist.

Scylla and Charybdis were living close to each other on top of two huge, adjacent rocks of the Strait of Messina, between Italy and Sicily, spreading fear among the sailors crossing the island. Scylla's task was to roll down huge rocks to the sea, destructing vessels that happened to pass by and eating sailors up.
