Christina Mirabilis was a Catholic saint and visionary. Born into a poor peasant family, she was orphaned by age 15. A few years later (sources disagree as to whether she was 21 or 22), she started to experience visions, which were accompanied by violent seizures.
Legend has it that after one such vision, she was believed dead, and astonished the town of St. Trond (where she lived) by suddenly standing up during her funeral, and beginning to recount her visions. She had seen Heaven, Hell and Purgatory and met God, who charged her with a mission to help free the souls atoning in Purgatory.
She lived in extreme privation for her entire life, strictly adhering to her vow of poverty to such an extent that she would seek out sufferings if she adjudged her current lot insufficient.
Despite all this, she lived to the age of 74. July 24, traditionally the day of her death, is now considered her feast day by the Catholic Church.
