between the devil and the deep blue sea

A choice between two evils. A term dating back to the early seventeenth century, it referred not to the devil of hellfire and brimstone but to a seam around a ship’s hull near the waterline. A sailor attempting to caulk this seam in heavy seas was in danger of falling overboard and drowning. The term was used figuratively—to mean any dilemma in which one faced danger—from that time on. It became a cliché about the middle of the eighteenth century.
