Mary of Egypt

Mary of Egypt is revered as the patron saint of penitents, most particularly in the Eastern Orthodox, Oriental Orthodox, and Eastern Catholic churches, as well as in the Roman Catholic.

Saint Mary, also known as Maria Aegyptica, was born somewhere in Egypt, and at the age of twelve ran away to the city of Alexandria where she lived an extremely dissolute life. In her Vita it states that she often refused the money offered for her sexual favors, as she was driven by an insatiable and an irrepressible passion, and that she mainly lived by begging, supplemented by spinning flax.
