Charybdis

Charybdis ( ; Ancient Greek: Χάρυβδις, romanized: Khárybdis, Attic Greek: [kʰárybdis]; Latin: Charybdis, Classical Latin: [kʰäˈrʏbd̪ɪs̠]) is a sea monster in Greek mythology. Charybdis, along with the sea monster Scylla, appears as a challenge to epic characters such as Odysseus, Jason, and Aeneas. The descriptions of Greek mythical chroniclers and Greek historians locates her in the Strait of Messina. The idiom "between Scylla and Charybdis" has come to mean being forced to choose between two similarly dangerous situations.
