Lorelei

Mark Twain wrote in his book "A Tramp Abroad" when he visited the Rhine about the Legend of the "Lorelei":

Lore (two syllables,) was a water nymph who used to sit on a high rock called Ley or Lei (pronounced like our word lie) in the Rhine, and lure boatmen to destruction in a furious rapid which marred the channel at that spot. She so bewitched them with her plaintive songs and her wonderful beauty that they forgot everything else to gaze up at her, and so they presently drifted among the broken reefs and were lost.
