Spanish nun, mystic, theologian and saint who co-founded the Discalced Carmelite Order.
As a child, she became fascinated by stories of saints, and ran away from home at the age of seven to try to become a Christian martyr.
She is known for two important Christian mystical and theological works, El Castillo Interior and Camino de Perfeccion.
She was the daughter of a knight and a highly pious mother, and she grew up with a brother named Rodrigo.
She and Rafael Baron were both Spanish saints and mystics, though they were separated by four centuries.
