What idiom is inspired by Scylla and Charybdis?

The idiom "stuck between a rock and a hard place" is inspired by the mythological figures Scylla and Charybdis, which represent dangerous obstacles. In Greek mythology, Scylla is a sea monster that preys on sailors, while Charybdis is a whirlpool that swallows ships whole. Navigators faced the dilemma of choosing between two perilous options—getting too close to Scylla means being devoured, while approaching Charybdis risks being swallowed by the whirlpool.

This idiom captures the essence of being confronted with two equally undesirable outcomes, much like Odysseus's impossible choice between the two threats. The other options, while they express various forms of difficult situations, do not encapsulate the essence of being trapped between two dangerous alternatives in quite the same way as the chosen idiom does.
