Being between Scylla and Charybdis is an idiom deriving from Greek mythology, which has been associated with the proverbial advice "to choose the lesser of two evils".[1] Several other idioms such as "on the horns of a dilemma", "between the devil and the deep blue sea", and "between a rock and a hard place" express similar meanings.[2] The mythical situation also developed a proverbial use in which seeking to choose between equally dangerous extremes is seen as leading inevitably to disaster.
