Seven Sleepers.
Seven noble youths of Ephesos, who fled in the Decian persecution to a cave in Mount Celion. After 230 years they awoke, but soon died, and their bodies were taken to Marseilles in a large stone coffin, still shown in Victors church. Their names are Constantine, Dionysius, John, Maximian, Malchus, Martinian, and Serapion. This fable took its rise from a misapprehension of the words, They fell asleep in the Lordi.e. died. (Gregory of Tours De Gloria Martyrum, i. 9.) (See Koran, xviii.: Golden Legend, etc.)
