Lorelei is the name of a feminine water spirit, similar to mermaids or Rhine maidens, associated with river rock in popular folklore and in works of music, art and literature.

The name comes from the old German words "lureln" (Rhine dialect for "murmuring") and the Celtic term "ley" (rock). The translation of the name would therefore be: "murmur rock" or "murmuring rock". The heavy currents, and a small waterfall in the area (still visible in the early 19th century) created a murmuring sound, and this combined with the special echo the rock produces to act as a sort of amplifier, giving the rock its name.[1] The murmuring is hard to hear today owing to the urbanization of the area. Other theories attribute the name to the many accidents, by combining the German verb "lauern" (to lurk, lie in wait) with the same "ley" ending, with the translation "lurking rock".
