An amazing story to be sure. Not much is known about her other than that she left her home to live a life of ascetical solitude in the cell of a Camaldolese convent in Rome where, in 1990, she died after forty-five years of religious solitude. She led a life of astounding mortification, a modern day anchoress, fasting on bread and water and occasional cooked herbs. She spoke to no one but her superior and, once a year, her confessor. The only exception was a visit from Pope Paul VI. She was served through a grill and, through another grill, she attended Mass and received Holy Communion. Her life story was written by Father Thomas Matus, a Camaldolese monk and it is available here from Amazon.
