Historical Setting

The legend holds that during the Decian persecution of the mid-third century, the seven young men hid in a cave near Ephesus to escape being forced to sacrifice to pagan gods, fell into a miraculous sleep, and awoke, by the story’s telling, generations later — emerging into a Christian empire under Theodosius II that had by then formally embraced the faith they had been persecuted for.
