During a persecution of Christians under the Emperor Decius, these seven Christian youths hid themselves in a cave outside Ephesus. When they were discovered, their persecutors sealed them in the cave to die; but God instead sent them a miraculous, life-preserving sleep. There they rested for about two hundred years. In the time of the Emperor Theodosius the Younger (408-450), a heresy that denied the bodily Resurrection of the dead began to trouble the people. The Emperor prayed God to reveal the truth to the people. At this time, some shepherds removed the stones blocking the cave in order to build a sheep-pen. They discovered the seven youths, who awoke in full health and told their miraculous story. The miracle was told throughout the empire, and the Emperor himself came to Ephesus and spoke with the youths. A week later, they again fell asleep, this time in death.
