Melusina. The most noted among French fairies. She was condemned to become every Saturday a serpent from the waist downward, as a punishment for having, by means of a charm, inclosed her father in a high mountain, in order to avenge an injury her mother had received from him. She married Raymond, Count of Poitiers, and, having been seen by him during her loathsome transformation - in violation of his solemn promise never to visit her on a Saturday - was immured in a subterranean dungeon of the castle of Lusignan.
