St. Castulus

Saint Castulus (died 286) is venerated as a martyr. According to tradition, he was the chamberlain (or officer, valet) of Emperor Diocletian and the husband of Irene of Rome, also venerated as a saint. A convert to the Christian religion, he sheltered Christians in his home and arranged for religious services inside the palace of the emperor. Among those he sheltered were Mark and Marcellian. He is one of the saints associated with the life and legend of Saint Sebastian. With his friend Saint Tiburtius, he converted many men and woman to Christianity and brought them to Pope Saint Caius to be baptized. He was betrayed by an apostate named Torquatus and taken before Fabian, prefect of the city. Castulus was tortured and executed by being buried alive in a sand pit on the Via Labicana. According to tradition, Irene subsequently buried the body of the martyred Sebastian. She was later martyred herself, around 288 AD. The feast of St. Castulus is kept on March 26.
