Cecilia was so highly venerated by the ancient Roman Church that her name was placed in the Canon of the Mass. Already in the fourth century there was a church of St. Cecilia in Trastevere, erected on the site where her home had stood. Her martyrdom probably occurred during the reign of Emperor Alexander Severus, about the year 230. In 1599 her grave was opened and her body found in a coffin of cypress wood. It lay incorrupt, as if she had just breathed forth her soul.
