Saint Olympias of Constantinople was a 4th-century Christian saint and ascetic who was known for her charitable works and her support of the Church. She was born into a wealthy family in Constantinople (present-day Istanbul, Turkey) and was married to a wealthy senator named Nebridius. However, after the death of her husband, Olympias dedicated her life to charitable works and became known for her generosity towards the poor and her support of the Church.
Olympias was a close friend of Saint John Chrysostom, the Patriarch of Constantinople, and supported him during his time of exile. She also provided financial support for the construction of the Church of the Holy Apostles in Constantinople and was known for her devotion to the Virgin Mary.
Saint Olympias is remembered as a model of Christian charity and is honored as a saint in the Catholic and Eastern Orthodox churches. Her feast day is celebrated on December 17th.
