Melusine (or Melusina) is a figure of European legends and folklore, a feminine spirit of fresh waters in sacred springs and rivers.
She is usually depicted as a woman who is a serpent or fish from the waist down (much like a mermaid)
The most famous literary version of Melusine tales, that of Jean d'Arras, compiled about 1382 - 1394 was worked into a collection of "spinning yarns" as told by ladies at their spinning.
