Member of the Roman patrician nobility. Adult convert who gave away his wealth to the poor. Deacon. Ministered to the Christian slaves who worked to build and staff the baths of Diocletian. Legend says that Cyriacus exorcised devils from Diocletian‘s daughter, Artemisia, who along with her mother, Saint Serena, converted to Christianity, and from Jobias the daughter of Shapur, King of Persia, which led to the conversion of the king‘s family and household. Tortured and martyred with twenty others during the persecutions of Diocletian and Maximian Herculeus. One of the Fourteen Holy Helpers.
