Righteous Mariamne "The Apostolic Virgin" and sister of the holy Apostle Philip (November 14), made a vow of virginity and became the companion of her brother Philip and the holy Apostle Bartholomew (June 11), actively assisting them in their apostolic work.
The Church historian Nicephorus Callistus describes their successful preaching in the Phrygian city of Hieropolis, where they were arrested and locked up in prison. They put the Apostle Philip to death on a cross, but St Mariamne and St Bartholomew were set free. St Bartholomew went to preach the Gospel in India. St Mariamne, after burying the body of St Philip, preached the Gospel at Lykaonia (Asia Minor). She died there in peace.
