Charybdis
Charybdis (; Ancient Greek: Χάρυβδις, romanized: Khárybdis, Attic Greek: [kʰá.ryb.dis̠]; Latin: Charybdis, Classical Latin: [kʰäˈrʏb.d̪ɪs]) is a sea monster in Greek mythology. She, with the sea monster Scylla, appears as a challenge to epic characters such as Odysseus, Jason, and Aeneas. Scholarship 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.
