“She is Melusina, the water goddess, and she is found in hidden springs and waterfalls in any forest in Christendom, even in those as far away as Greece. (...) A man may love her if he keeps her secret and lets her alone when she wants to bathe, and she may love him in return until he breaks his word, as men always do, and she sweeps him into the depths with her fishy tail, and turns his faithless blood to water. The tragedy of Melusina, whatever language tells it, whatever tune it sings, is that a man will always promise more than he can do to a woman he cannot understand.”
― Philippa Gregory
