What is a short summary of the story, Doña Jeronima, from the collection, The Woman Who Had Two Navels?

Doña Jeronima is a love story that tracks the making of a fable through time and space, as a woman named Jeromina tries to claim the Archbishop as her lover, as he allegedly made an oath to her years before. The Archbishop does not believe Doña Jeronima, and she even admits that she had acted out of her own pride, and is sent to a cave for penance. However, the Archbishop sees a vision of his ghost traveling down the river to join Doña Jeronima, refiguring a pagan myth about a nymph who would lure men to her cave from the river. Soon after, the Archbishop fulfills his oath after his death.
