Saint Pelagia of Antioch was converted to be a Christian suddenly. Being only 15 years old, she desired to keep her chastity and threw herself off the rooftop. She died instantly in Antioch, Syria on feast day on June 9th probably during the persecution of Christians of the Roman emperor Diocletian. St Ambrose and St. John Chrysostom celebrated her martyrdom in a homily.
Pelagia lived during the 4th or 5th Century in Antioch, Syria or Ancient Greece which is near present-day Antakya, Turkey. She was a 15-year old Christian virgin who killed herself to preserve her chastity during the Diocletian or Great persecution of Christianity by the Roman Empire - the most severe and last persecution of them by the Empire. Her actions were praised by St. Ambrose and St. John Chrysostom. Her story influences the legends of Pelagia the Harlot and Pelagia Margaret of Tarsus.
