St. Chrysanthus came with his wife St. Daria from the East to Rome, some time in the Third Century. They were accused of being Christians, and after suffering many torments their lives were closed by a glorius martyrdom in one of the persecutions, probably that of Valerian, about the year 237. Of them the Byzantine Liturgy says: “Chrysanthus and Daria live in heaven, though they are dead, having been buried alive in one grave. The inseparable pair were entombed on March 19.”
