But Polycarp also was not only instructed by apostles, and conversed with many who had seen Christ, but was also, by apostles in Asia, appointed bishop of the Church in Smyrna, whom I also saw in my early youth, for he tarried [on earth] a very long time, and, when a very old man, gloriously and most nobly suffering martyrdom, departed this life, having always taught the things which he had learned from the apostles, and which the Church has handed down, and which alone are true.
He is generally thought to have been martyred in his eighties or nineties, somewhere around AD 155 or so. From his Epistle to the Philippians:
For I trust that ye are well versed in the Sacred Scriptures, and that nothing is hid from you; but to me this privilege is not yet granted. It is declared then in these Scriptures, "Be ye angry, and sin not," and, "Let not the sun go down upon your wrath." Happy is he who remembers this, which I believe to be the case with you. But may the God and Father of our Lord Jesus Christ, and Jesus Christ Himself, who is the Son of God, and our everlasting High Priest, build you up in faith and truth, and in all meekness, gentleness, patience, long-suffering, forbearance, and purity; and may He bestow on you a lot and portion among His saints, and on us with you, and on all that are under heaven, who shall believe in our Lord Jesus Christ, and in His Father, who raised Him from the dead. Pray for all the saints. Pray also for kings, and potentates, and princes, and for those that persecute and hate you, and for the enemies of the cross, that your fruit may be manifest to all, and that ye may be perfect in Him.
