St. Agathonicus was a citizen of Nicomedia and a Christian by faith. With great zeal he converted the Hellenes from idolatry and instructed them in the true Faith. At Emperor Maximian’s orders, the regional governor cruelly persecuted the Christians. The deputy captured St. Zoticus in a place called Carpe. He crucified Zoticus’s disciples and brought Zoticus himself to Nicomedia–where he also captured and bound St. Agathonicus, Princeps, Theoprepius (Bogoljepa), Acindynus, Severianus, Zeno and many others. Securely bound, they were all taken to Byzantium.  As they traveled, Saints Zoticus, Theoprepius and Acindynus died of their many wounds and exhaustion. Severianus was slain near Chalcedon. Agathonicus and the others were taken to Silybria, in Thrace. There, after being torture in the emperor’s presence, they were beheaded, and entered into eternal life and the joy of their Lord.
