Agathangelus of Rome

Saint Agathangelus the Martyr was a deacon of the Church of Rome and a disciple of Saint Clement of Ancyra. He received the crown of martyrdom in the year 312, at Ancyra, in the time of the persecution begun by Diocletian, together with his teacher.

Agathangelus met Clement when the latter lay in prison at Rome, confined by order of the emperor Diocletian. He stayed at his side as a disciple and travelled with him back to Ancyra in Galatia. There both were beheaded, in the reign of the emperor Maximian, as the Greek source tells.

Saints Clement and Agathangelus are commemorated together. The Orthodox Church remembers them on 23 January by the old calendar, which is 5 February by the new.
