She was a Persian noblewoman during the reign of Chosroës II (590-628). Through a vision of an angel, she came to belief in Christ and received holy baptism; her name in baptism was Maria. Her furious husband reported her to King Chosroës, who had her thrown into a foul dungeon known as Oblivion for eighteen years. During these years she was repeatedly told to renounce Christ and was tormented in many ways. She was thrown to venomous snakes, which refused to harm her. Some lawless young men were sent to her cell to defile her, but God made her invisible to them. Many Persians, amazed and inspired by her patient sufferings, accepted Christ. She was finally set free through the visitation of an angel, traveled to Jerusalem and Constantinople, and reposed in peace.
  She is commemorated July 12 on the Slavic calendar. Oddly, she is called a Martyr in all accounts, though she died free and in peace; presumably her eighteen years of cruel imprisonment earned her the title.
