Reading from the Synaxarion:

Tatiana the Martyr of Rome

Saint Tatiana was the daughter of a most distinguished consul of Rome. She became a deaconess of the Church, and for her confession of the Faith of Christ, she endured many torments. As she was suffering, angels punished her tormentors with the same torments they inflicted on her, until they cried out that they could no longer endure the scourges invisibly brought upon them. She was beheaded during the reign of Alexander Severus (111-135).
