In her survey of the "Transformations of Circe", Judith Yarnall comments of this figure, who started out as a comparatively minor goddess of unclear origin, that "What we know for certain – what Western literature attests to – is her remarkable staying power…These different versions of Circe's myth can be seen as mirrors, sometimes clouded and sometimes clear, of the fantasies and assumptions of the cultures that produced them." After appearing as just one of the characters that Odysseus encounters on his wandering, "Circe herself, in the twists and turns of her story through the centuries, has gone through far more metamorphoses than those she inflicted on Odysseus's companions."
