They were all of the Seventy. Stachys was an assistant to St. Andrew the First-called. St. Andrew appointed him Bishop of Byzantium. He established the church in Argyropolis and governed his flock faithfully and zealously. After sixteen years as bishop, he entered peacefully into rest in the Lord. Amplias and Urban worked likewise with St. Andrew, and were ordained bishops by him–Amplias in Lydda of Odyssopolis in Judea, and Urban in Macedonia. Both died as martyrs for Christ the Lord. Narcissus was appointed Bishop of Athens by the Apostle Philip. St. Apelles was Bishop of Heraclea in Trachis. Aristobulus, brother of the Apostle Barnabas, preached the Christian Faith in Britain and reposed peacefully there.
