Saint Bucolus, Bishop of Smyrna, was a disciple of the holy Apostle and Evangelist John the Theologian, and
became the first Bishop of Smyrna (Asia Minor).
By the grace of God, St Bucolus converted many of the pagans to Christ and baptized them. As a wise and experienced guide, he defended his flock from the darkness of heresy.
He died in peace between the years 100-105. He entrusted his flock to St Polycarp (February 23), one of the Apostolic Fathers, who was also a disciple of the holy Apostle John the Theologian. At the grave of St Bucolus grew a myrtle tree, which healed the sick.
