Melusine is one of the pre-Christian water-faeries {{citation needed|date=December 2013}} who were sometimes responsible for [[changeling]]s. The "[[Lady of the Lake]]", who spirited away the infant [[Lancelot]] and raised the child, was such a water nymph.
A folktale tradition of a demon wife similar to Melusine appears in early English literature. According to the chronicler [[Gerald of Wales]], [[Richard I of England]] was fond of telling a tale that he was a descendant of an unnamed countess of Anjou.<ref>[[Flori, Jean]] (1999), Richard Coeur de Lion: le roi-chevalier, Paris: Biographie Payot, {{ISBN|978-2-228-89272-8}} {{in lang|fr}}</ref> In the legend, an early Count of Anjou encountered a beautiful woman from a foreign land. They were married and had four sons. However, the count became troubled because his wife only attended church infrequently, and always left in the middle of Mass. One day he had four of his men forcibly restrain his wife as she rose to leave the church. She evaded the men and, in full view of the congregation, flew out of the church through its highest window. She carried her two youngest sons away with her. One of the remaining sons was the ancestor of the later Counts of Anjou, their troublesome nature being the result of their demonic background.<ref>Huscroft, R.
