Hermylus was a deacon in Singidunum (modern-day Belgrade) during the reign of Licinius. When he was arrested he joyously welcomed the soldiers who came to seize him. When he confessed Christ before the magistrate, he was beaten, tormented, then thrown in jail. There he prayed to be allowed to partake in Christ's saving Passion, and heard a voice assuring him that in three days he would receive a Martyr's crown.   Stratonicus, his jailer, was a kind-hearted man and secretly a Christian, and wept to see the torments to which Hermylus was subjected. Seeing this, the soldiers began to question him; and, seeing that his hour had come, he in turn openly confessed Christ. For this he was seized, flogged and thrown into prison with his brother in Christ. The following day, both were bound, tied in a net and thrown into the Danube, where they received their divinely-promised crowns. Their bodies were washed up a few days later, recovered by Christians and buried with honor.
