In Hero-journey
In Joseph Campbell's classic work The Hero with a Thousand Faces, the first encounter of the hero on his journey is with a protective figure who provides him with amulets or magic devices against the dangers he will face. The crone is one of the most common of these protective figures.
| “ | The child of destiny has to face a long period of obscurity. This is a time of extreme danger, impediment, or disgrace. He is thrown inward to his own depths or outward to the unknown; either way, what he touches is a darkness unexplored. And this is a zone of unsuspected presences, benign as well as malignant: an angel appears, a helpful animal, a fisherman, a hunter, crone, or peasant. | ” |
Campbell links the "helpful crone" to the fairy godmother. The wicked fairy godmother sometimes appears in the guise of a crone.
