J. C. Cooper, in The Dictionary of Christianity, writes that Saint Valentine was "a priest of Rome who was imprisoned for succouring persecuted Christians. " Contemporary records of Saint Valentine were most probably destroyed during this Diocletianic Persecution in the early 4th century. In the 5th or 6th century, a work called Passio Marii et Marthae published a story of martyrdom for Saint Valentine of Rome, perhaps by borrowing tortures that happened to other saints, as was usual in the literature of that period. The same events are also found in Bede's Martyrology, which was compiled in the 8th century. It states that Saint Valentine was persecuted as a Christian and interrogated by Roman Emperor Claudius II in person. Claudius was impressed by Valentine and had a discussion with him, attempting to get him to convert to Roman paganism in order to save his life. Valentine refused and tried to convert Claudius to Christianity instead. Because of this, he was executed. Before his execution, he is reported to have performed a miracle by healing Julia, the blind daughter of his jailer Asterius. The jailer's daughter and his forty-six member household (family members and servants) came to believe in Jesus and were baptized.
