St. Viviana is commemorated on December 2.
She is also considered to be as an intercessor for persons with mental illness. She, too, lived before the tragic schism of 1054. She was martyred under Emperor Julian the Apostate.
“With her eyes raised to heaven, she stood motionless during her martyrdom, until her whole body was one mass of bloody wounds, and she gave her unspotted soul to the keeping of her heavenly Bridegroom. According to the tyrant’s command, her holy body was left on the public road, to serve as a prey to the dogs but it remained untouched, until a pious priest carried it secretly away, and buried it beside the grave of her mother and sister.”
Her life is profiled on the website of the Antiochian Orthodox Christian Archdiocese of North America:
