They were of the Seventy. St Stachys was a helper of St Andrew the First-Called, who made him bishop of Byzantium. He built a church in Argyropolis, and governed his flock with faithfulness and zeal. After sixteen years as bishop, he entered peacefully into rest in the Lord. Amplias and Urban were also fellow-workers with St Andrew, and were made bishop by him, Amplias in Lydda and Urban in Macedonia. They both died as martyrs for Christ the Lord. Narcissus was made Bishop of Athens by the Apostle Philip, and holy Apelles was Bishop of Heraklion in Trachis. Aristobulus, the brother of the Apostle Barnabas, preached the Christian faith in Britain and died peacefully there. He is also commemorated on March 16th.
