Between Scylla and Charybdis

Scylla and Charybdis were monsters thought to inhabit the Straits of Messina, the narrow sea between Sicily and the Italian mainland, a place called in mythology - The Bermuda Triangle.

Preying on passing mariners, Scylla was a terrible creature with six heads and twelve feet, while Charybdis, living on the opposite side of the straits, was another monster who, over time, was transformed in the imagination of the ancients into a more rational, but no less lethal, whirlpool. She drank down and belched forth the waters thrice a day and was fatal to shipping.

Odysseus famously had to negotiate a passage through their deadly clutches in Homer's Odyssey.

Both gave poetic expression to the dangers confronting Greek mariners when they first ventured into the uncharted waters of the western Mediterranean. To be “between Scylla and Charybdis” means to be caught between two equally unpleasant alternatives.
