The Account of Her Martyrdom
The surviving account of Pelagia is a hagiographical legend rather than a documented biography. As it is related, the son of the emperor Diocletian fell in love with Pelagia and sought to marry her. She refused, saying that she had sworn to preserve her virginity and was wedded to Christ; in despair, the emperor's son is said to have taken his own life.
Pelagia was then sent to Rome by her pagan mother. When Diocletian himself proposed marriage and was rejected, with Pelagia calling the emperor insane, he ordered her execution. By tradition she was burned to death, some accounts placing her death within a heated brazen bull. The narrative relates that as her flesh melted a fragrance of myrrh spread through the city, and that lions afterward guarded her remains from being devoured. For this reported fragrance she is counted among the myrrh-streaming saints.
Historical Note
Modern accounts observe that there is little historical basis for the embellished legend. In particular, Diocletian is recorded as having a daughter, Valeria, but no sons, which undercuts the central episode of the emperor's son. Scholars suggest the developed story grew up around the commemoration of a genuine historical martyr named Pelagia at Tarsus, whose memory the Church has preserved.
The dataset records her era as Pre-Nicene and her region of origin as Asia Minor, consistent with a martyrdom under the Diocletianic persecution in Cilicia.
Relics & Shrines
By tradition her relics were recovered and honored after the persecutions ended. Accounts associate the bishop Linus with the recovery of her remains, and report that Constantine the Great constructed a church at the reputed site of her burial.
Veneration
Pelagia is commemorated in the Eastern Orthodox Church on May 4 and on October 7 (October 8 in some calendars). She is also venerated in the Roman Catholic tradition, where her feast is kept on May 4.
