Polycarp was a disciple of the Apostles, bishop of Smyrna, and a friend of St Ignatius of Antioch. He went to Rome to confer with Pope Anicetus about the celebration of Easter. He was martyred at Smyrna in about 155 by being burnt to death in the stadium. Polycarp is an important figure in the history of the Church because he is one of the earliest Christians whose writings still survive. He bears witness to the beliefs of the early Christians and the early stages of the development of doctrine.
