Image of St. Aristobulus

Martyred disciple of Christ, one of the seventy-two sent out into the world by the early Church. He is possibly mentioned by St. Paul and is identified with Zebedee, the father of Sts. James and John. Aristobulus preached in Britain, although no documentation supports this or his martyrdom in the British Isles.
