Mother Mariana of the Purification (November 5, 1623 in Lisbon – December 8, 1695 in Beja) was a nun of the Carmelite Order of the Ancient Observance who, having been born in Lisbon, Portugal, and lived and professed her religious vows at the Carmelite Convent of Our Lady of Hope in Beja, Portugal, died with the odor of sanctity. During her life, she reported several apparitions of the Child Jesus and left many autobiographical writings with ascetic interest.
