Saint Aristibule (Aristobulus) is one of the seventy Apostles (Luke 10:10) sent out to preach. He is possibly mentioned by St. Paul and is identified with Zebedee, the father of Sts. James and John. He later became a bishop to the Celts of northern Spain and Britain and is known as the Apostle of Britain. Hippolytus writing in AD 160, the Martyrologies of the Greek Church, (and others) state that he preached in Britain. It is believed he was martyred in Wales although there is no documentation for this.

Troparion of the Apostles tone 5
Let us acclaim Stachys,/ Apelles, Amplias, Urban, Narcissus and Aristobulus/ as a six-stringed harp of the Spirit/ that sings of
God's marvellous gifts to mankind./ As divine apostles they pray for us.
